Dry eye (KCS) in dogs: the Schirmer tear test, lifelong drops and which breeds get it

Signs of Keratoconjunctivitis sicca

The 8 signs to watch for are listed below. Any one of them is a reason to consult your nearby vet; none of them is a diagnosis.

• Thick yellow-green discharge that comes back within hours of wiping
• A dull, dry-looking eye surface that no longer catches the light
• Redness of the white of the eye that does not settle
• Squinting or holding the eye partly shut
• Pawing or rubbing the face against furniture or your leg
• Dark pigment or visible blood vessels creeping onto the cornea
• Both eyes changing together over weeks or months
• A dry nostril on the same side as a single affected eye

Breeds on this site that document this condition

Each breed page below carries the figure for this condition with its denominator and its source. The 10 breeds listed are the ones on this site that document it, not a ranking of risk.

What dry eye is, and how many dogs get it

Dry eye in dogs is a failure of the tear gland, not a failure of hygiene. The medical name is keratoconjunctivitis sicca, and it means the eye does not make enough of the watery part of the tear film, so the surface is inflamed, sore and open to ulcers. In a VetCompass study of 363,898 dogs under UK primary veterinary care, 1,456 had it, an overall prevalence of 0.40 percent, or about one dog in 250 Royal Veterinary College VetCompass.

Read that denominator before you read anything else on this page. The figure comes from electronic patient records at practices covering more than 30 percent of UK veterinary practices, not from a referral eye clinic, so it is close to a real population rate rather than a caseload. The same study found 430 new cases during 2013, a one-year incidence risk of 0.12 percent with a 95 percent confidence interval of 0.11 to 0.13. India has no equivalent dataset, which is why this page publishes the British one and says whose dogs it counted.

The tear film has three layers and dry eye attacks one of them. The lipid layer comes from the meibomian glands in the eyelid margin, the watery aqueous layer comes from the orbital and nictitans lacrimal glands, and the mucin layer comes from goblet cells in the conjunctiva. Quantitative dry eye is a loss of the aqueous layer and is what a Schirmer tear test measures; qualitative dry eye is a loss of the lipid or mucin layers and shows instead as a short tear film break-up time. Almost everything written for owners, including this page, is about the quantitative kind.

The commonest cause is the dog's own immune system. Immune-mediated inflammation of the tear-producing glands accounts for most canine cases, it is lifelong, and it is most often diagnosed in middle-aged dogs Best LJ, Hendrix DVH. The average age at first diagnosis in the VetCompass cohort was 7.5 years, and dogs aged 12 years or over carried 29.4 times the risk of dogs under 3.

The causes an owner can actually act on

Nine causes are documented and several of them are things somebody did to the dog. Distemper infection, certain sulfa-derivative medicines, the anti-inflammatory etodolac, radiation to the head, trauma to the gland or its nerves, congenital absence of tear tissue and surgical removal of the third eyelid gland all appear in the peer-reviewed cause table alongside immune-mediated adenitis. Cornell adds chronic allergy, diabetes and hypothyroidism to that list.

Two of those causes have a clock on them and that changes what you do. Dry eye from a sulfa-derivative medicine typically begins within 30 days of starting it and may resolve in 45 to 60 days once it is stopped, or may become lifelong; dry eye from etodolac is more likely to recover if the drug was given for less than 6 months. So a dog that develops a gummy eye weeks after starting a new medicine has a history worth telling the vet, and the vet, not the owner, decides what happens to that prescription.

General anaesthesia suppresses tear production too, and the number is bigger than most owners expect. Tear production falls significantly for up to 24 hours after a general anaesthetic, which is why eye lubricant belongs in every sedation and anaesthesia plan and should be continued until the dog is fully awake and blinking properly. If your dog is booked for sterilisation or a dental, that is a fair question to ask at admission.

One more group of dogs is worth naming because the rest of this page does not apply to them cleanly. In neurogenic dry eye the nerve supply to the gland fails rather than the gland itself, only one eye is usually affected, and the nostril on the same side is dry as well. The peer-reviewed cause table records it as idiopathic, commonest in middle-aged female dogs, and says some cases resolve on their own. That is the one presentation where a one-sided dry eye is expected rather than surprising.

What dry eye looks like at home, and when the eye needs a vet today

Dry eye looks like a dirty eye, which is exactly why it gets missed for months. The discharge is thick and yellow-green rather than watery, the eye looks dull and lustreless instead of wet, and the white is red. Owners wipe it away every morning, it comes back every morning, and nobody measures a tear film until somebody thinks to.

The reason the discharge is thick is worth understanding, because it tells you why wiping fails. When the watery layer goes, the mucin and lipid layers are left behind without enough fluid to dilute them, so what reaches the eyelid is mucus rather than tears. A severe mucopurulent discharge suggests a secondary bacterial infection on top of the dryness, which is a second problem needing its own treatment.

Then the cornea starts changing, and those changes are the ones that cost vision. Chronic surface irritation produces conjunctival redness, squamous change and hyperkeratinisation of the surface epithelium, and inflammatory cells and blood vessels move into the front of the corneal stroma, laying down pigment, lipid and calcium. Those deposits actually stabilise the cornea and make it less likely to ulcerate, and they can also take the sight. Untreated dry eye progresses to scarring, blood vessel formation and secondary infection, and can end in permanent vision loss.

The pain is real and it is under-reported because dogs hide it. PDSA describes untreated dry eye as extremely painful and quotes the human description of it as having sand in the eye, and says that with treatment dogs with dry eye can live a pain-free, happy life. Eight things are worth watching for at home.

• Thick yellow-green discharge that rebuilds within hours of being wiped.
• A dull, dry-looking surface where the eye used to catch the light.
• Redness of the white of the eye that does not settle.
• Squinting or holding the eye half shut, which is pain, not sleepiness.
• Pawing or rubbing the face on furniture, a rug or your leg.
• Dark pigment or visible blood vessels creeping onto the cornea in longer-standing cases.
• Both eyes going the same way together, since most dry eye is bilateral.
• A dry nostril on the same side as a single dry eye, which points to the neurogenic form.

Why Indian owners in particular wait too long

Three ordinary Indian conditions imitate the early signs and buy the disease months of cover. Dust, monsoon damp and long facial hair all produce eye discharge in healthy dogs, and our guide to monsoon care for dogs in India covers the ordinary version. The page that ranks first in India for this condition opens by describing exactly that trap, an owner wiping away crusted discharge morning after morning and the gunk coming back. The difference is that ordinary discharge clears and dry-eye discharge does not, and only a strip of paper can tell you which you are looking at. Humid monsoon air cuts evaporation from the eye surface, which is the job the lipid layer of the tear film does, so a dog with an early aqueous deficit can look more comfortable through a humid July and worse again in a dry April without the gland having changed at all.

Facial conformation makes the confusion worse in the breeds India keeps. Many of the breeds predisposed to dry eye also carry distichia, a shallow orbit with incomplete eyelid closure and entropion of the inner corner, and every one of those independently causes conjunctivitis and keratitis. A flat-faced dog can therefore have a sore, weeping eye for two entirely different reasons at once, which is an argument for the test rather than for a guess. Our page on entropion in dogs covers the eyelid side of that.

The Schirmer tear test: what the strip measures and what the number means

To diagnose dry eye, a vet folds a calibrated paper strip over the lower eyelid, leaves it for one minute and reads how far the tears have wicked up it in millimetres. That is the whole test. Normal tear production in a dog is more than 15 mm in a minute, and a result below that is what raises dry eye.

The version that matters is the one done without anaesthetic. A Schirmer tear test 1, performed with no surface anaesthetic applied first, measures reflex tear production and is the cornerstone of diagnosing the quantitative disease. The reading is interpreted alongside the clinical signs rather than on its own, which is why the vet examines the eye first and tests second.

A second test usually follows the strip and it is looking for damage rather than dryness. Because corneal ulcers happen secondary to dry eye, the vet commonly applies a fluorescein stain, a dye that sticks to and lights up any break in the corneal surface. Where qualitative dry eye is suspected, the tear film break-up time is timed under a blue light instead, and a normal break-up time is 20 seconds or more, while animals with a quantitative deficiency often break up in under 5 seconds.

Here is the part no ranking page prints, and it is the reason to test early rather than late. How low the first reading is predicts how well the dog will respond. Dogs whose starting Schirmer reading is below 2 mm in a minute respond with increased tear secretion in approximately 50 percent of cases, while dogs at or above 2 mm have approximately an 80 percent chance of responding. Cornell says the same thing in plain words, that dogs with very low or absent tear production at diagnosis tend to respond less well.

That ladder is the whole argument for testing a predisposed dog before anything is wrong. The VetCompass authors put it in their own clinical-significance line, that quantitative tear tests are recommended within yearly health examinations for breeds with evidence of predisposition to dry eye, and that such testing might in future be considered within eye testing for breeding. The Royal Veterinary College's own summary goes further and says veterinarians should test tear production as part of the annual physical examination of all dogs, with predisposed breeds watched very carefully as they approach later life.

Why the test comes before the drops

Testing before treating protects the dog in three separate ways. It separates quantitative dry eye from the qualitative kind, which has a normal Schirmer reading and a different management. It gives a baseline number, without which nobody can tell later whether treatment is working, since the recheck is a repeat Schirmer test rather than an opinion. And it catches the corneal ulcer, because an ulcerated eye and an unulcerated eye are not treated the same way.

The test is also the cheapest thing in the room. A strip costs a fraction of one consultation, takes one minute per eye, needs no sedation and no imaging, and is available to any small-animal practice; in a country where ICAR-IVRI Izatnagar charges Rs 30.00 to register a dog or cat in normal clinic hours, the barrier is not money. The barrier is that nobody asks for it. If you own one of the breeds in the next section, ask for a Schirmer tear test at the annual vaccination visit and write the number in the vaccination card.

Cherry eye and dry eye are the same story six years apart

Cutting out a prolapsed third eyelid gland removes a tear gland, and the tear loss is measurable. When five young Beagles had the gland excised and were followed for a year, the modified Schirmer tear test fell by 37 percent within two weeks and by 60 percent at one year, the tear film break-up time dropped from 24.0 seconds before surgery to 13.5 seconds at five months, and vital staining at one year showed microinjury of the surface epithelium in every operated eye.

A second experiment, published nine years earlier, tested the three options against each other. Eighteen prolapsed glands in 17 Beagles were randomly allocated to being left alone, excised, or surgically repositioned, with Schirmer tests on five consecutive days at eleven time points out to 24 weeks. The control eyes gave a population mean of 22.2 plus or minus 2.1 mm per minute, and the excised group showed a significant fall in lacrimation after the gland was removed. Leaving the gland prolapsed was worse again, with complications in 4 of 6 untreated eyes against 0 of 12 in the excised and repositioned groups together.

So the instruction from those two papers is the same and it is narrow. Put the gland back, do not cut it out, and do not leave it hanging out either. Our page on cherry eye in dogs covers the operation itself, the techniques and what to ask a surgeon; this page is what happens afterwards to the dogs whose gland went in the bin.

The replacement operations, and their tear results

Three published series of gland replacement report what happened to tear production, and none of them reports a collapse. In a prospective study of 30 dogs and 44 eyes using a perilimbal pocket, the success rate was 90.9 percent, tear production and ocular health were unaffected in the 17 eyes followed for six months or more, and there was a statistically significant increase between the before and after Schirmer readings. In a retrospective series of 100 dogs and 122 eyes anchored with a suture around the ventral rectus muscle, there were no recurrences at all, and the 5 dogs that already had dry eye before surgery all had improved Schirmer readings afterwards on surgery plus medical treatment.

The largest and most recent series is also the most honest about the residual risk. A variant of the pocket technique in 101 dogs and 126 eyes operated between 2015 and 2024 repositioned the gland successfully in 125 of 126 eyes, 99.2 percent, at the first attempt, with a mean follow-up of 1,190 days. Additional complications occurred in 14 of 101 dogs, 13.9 percent, including keratoconjunctivitis sicca and ulcerative keratoconjunctivitis of varying severity, and the authors say openly that with that follow-up length and that number of cases they could not tell whether those problems were related to the surgery. Publish that caveat, because it is the honest state of the evidence.

The population-scale proof, from one programme measuring both diseases

The strongest evidence that these two diseases belong together was never assembled for owners, and it should have been. The VetCompass programme measured cherry eye in 905,543 UK dogs and dry eye in 363,898 UK dogs, and the breed ladders overlap where it matters. Three of the five breeds with the highest cherry eye odds also sit among the breeds with the highest dry eye odds, and one breed tops one list while sitting fifth on the other.

Now put the two clocks side by side, because that is the finding. The median age at first cherry eye diagnosis was 0.63 years, and dogs under one year old carried 10.82 times the odds of dogs aged two to under four. The average age at first dry eye diagnosis was 7.5 years. The gland comes out at about eight months old and the dry eye is diagnosed about seven years later, which is far too long a gap for any owner to connect the two by memory. That is why this page and the cherry eye page carry each other's evidence.

The manufacturer of the licensed treatment says something about these dogs that nobody quotes. The filed label for the ciclosporin eye ointment licensed for canine dry eye states in its precautions that its clinical effects have not been determined in dogs whose dry eye is due to surgical removal of the third eyelid gland, alongside congenital absence of tear tissue, sulfonamide use, distemper, metabolic disease and facial nerve paralysis. A dog whose cherry eye was excised is therefore in the one group where the standard first-line treatment has no established effect on the label.

One breed has been measured twice and the second measurement is the blunter one. In the VetCompass study devoted to the breed, random samples of 2,662 English Bulldogs against 22,039 other dogs gave a prolapsed nictitating membrane gland odds ratio of 26.79 (95 percent CI 18.61 to 38.58), the second highest of the 24 disorders the breed was predisposed to, behind only skin fold dermatitis at 38.12. The same paper records that English Bulldogs were younger than the comparison dogs, at a mean of 2.65 years against 4.42, which is the age at which the gland decision is being made. If you own a Bulldog, assume the conversation is coming.

Treatment for dry eye, in general terms, and whether it can be reversed

Dry eye is managed for life rather than cured, and the honest framing is that treatment buys comfort and vision rather than a normal gland. Keratoconjunctivitis sicca is a chronic condition that generally requires lifelong treatment, and in most patients topical therapy is required indefinitely Best LJ, Hendrix DVH. PDSA puts it to owners in one line, that dry eye usually cannot be cured but can often be well managed with treatment from a vet.

Treatment has two jobs and they are different. Tear stimulants try to restart the gland by calming the immune attack on it, and tear replacements lubricate the surface in the meantime. This page names drug classes and what they do; it prints no dose and no application schedule, because the dose is the decision of the veterinarian looking at your dog's eye.

Ciclosporin is the licensed first line and its trial numbers are on the public label. In a controlled field trial run by veterinary ophthalmologists across nine American states, 132 dogs with dry eye were enrolled and 124 were evaluated for efficacy, randomly assigned to the active ointment or the placebo vehicle for 12 weeks. The treated dogs gained an average 8 to 9 mm on the Schirmer test against 3 to 4 mm for the placebo, with most of the gain, about 6 mm, arriving in the first week, and overall improvement was noted in 81 percent of treated eyes. An independent review reports the same order of effect, with 81.8 percent of dogs improving on topical ciclosporin, which blocks interleukin-2 production in the lacrimal gland and also appears to stimulate lacrimation directly.

One line in that label matters more than the headline number. Clinical improvement does not depend on the Schirmer reading going up. Some dogs improved clinically, meaning the conjunctival and corneal disease receded, with no increase in tear production at all, which is thought to happen through suppression of inflammation on the ocular surface. With long-term use ciclosporin reduces corneal pigmentation and blood vessel growth even in dogs whose tear production never rises, which is why treatment is often continued in those dogs. A flat Schirmer number is therefore not by itself a reason to stop.

Tacrolimus is the second line and it is a different legal animal. It has a similar but more potent mechanism, patients unresponsive to ciclosporin may respond to it, and it may reduce the pigmentation of chronic dry eye even where tear production does not rise, though no long-term studies exist. Using tacrolimus for canine dry eye is off-label, so the regulator-approved ciclosporin preparation is the first-line treatment and tacrolimus is reserved for cases that do not respond to it. It is also generally compounded rather than bought as a licensed ophthalmic product, and the formulations vary.

Two other classes appear and each has a narrow job. Pilocarpine is a parasympathomimetic used for the neurogenic form, the cases identified by a dry nostril on the same side as the low Schirmer reading, and it has a narrow therapeutic window. Topical antibiotics are used when a heavy mucopurulent discharge suggests secondary bacterial infection, and anti-inflammatories only in eyes that take up no fluorescein dye, because a dog with dry eye can develop ulcerative keratitis and keratomalacia.

How long before you know it is working

Give it weeks, not days, and know the two published deadlines. Most dogs show improvement within a few weeks, though in some cases signs of improvement take up to twelve weeks. The clinical rule is stricter and more useful: treatment failure on ciclosporin can only be diagnosed after 12 weeks of consistent topical application, with a Schirmer recheck at one month. An owner who stops at three weeks because nothing has changed has not tested the treatment, they have abandoned it.

Surgery exists and it is a last resort with a specific name. After three to six months of medical therapy with no response, parotid duct transposition can be considered, in which the salivary duct is dissected free, mobilised and moved so that saliva lubricates the eye. It is usually done by a board-certified ophthalmologist, it is not always successful, and even when it works patients often still need ongoing topical therapy Cornell University College of Veterinary…. Its own complication list includes duct severance, duct occlusion by scar, white mineral deposits on the cornea, facial dermatitis and excessive saliva.

The treatments being tested, and one that mostly did not work

Two newer approaches have controlled numbers and a page that cites them should print both outcomes. In a Brazilian trial of 66 eyes from 33 dogs in three equal groups, the topical immunosuppressant ointment produced a significant rise in tear production, tear meniscus and conjunctival goblet cell count, while injectable homologous platelet-rich plasma produced a significantly greater fall in conjunctival lymphocyte and neutrophil counts, and the authors concluded the injection is a cheaper alternative or an adjuvant rather than a replacement. A separate trial by an overlapping team, in 22 dogs and 44 eyes with bilateral disease, found the injection worked better still when combined with an oral omega-3 supplement, with significantly higher tear film break-up times from month three onwards and a greater rise in goblet cell numbers.

The stem cell result went the other way and it is the more instructive one. A team at the University of California Davis injected autologous mesenchymal stromal cells into the lacrimal gland region of 4 dogs that met stringent criteria, and reports a high failure rate simply for inclusion. The injections were well tolerated and no adverse ocular events occurred, but the responses varied: one dog held a 5.5-fold rise in tear production, two had small temporary rises of 0.6 to 0.7-fold, one had no detectable rise over six months, and repeated injections did not sustain the response. A review from the Division of Surgery at ICAR-IVRI Izatnagar surveys the same field and reports it as promising rather than proven. Nobody should be sold a stem cell cure for canine dry eye on four dogs.

Which dry eye eye preparations are actually sold in India

India's own drug regulator has approved a ciclosporin eye drop by name for this disease, and has approved no tacrolimus eye preparation at all. The Central Drugs Standard Control Organisation register carries an entry for ciclosporin 0.05 percent eye drops, indicated for treatment of moderate to severe dry eye syndrome (keratoconjunctivitis sicca), approved on 10 March 2003, and a second entry adding a higher strength for ophthalmic use on 2 June 2006.

Read what that register is before you read the rows. CDSCO's list is a register of new drugs approved for human use in India, and India licenses veterinary medicines separately, so an entry proves the molecule exists in an Indian eye preparation rather than that it is licensed for dogs. The rendered register carried 679,155 characters of rows when it was pulled on 24 September 2026, because a plain fetch of the same page returns a 1,451-character JavaScript shell and would have shown nothing.

Now the tacrolimus finding, and it is a clean one. The same register carries eight tacrolimus rows and not one of them is an ophthalmic preparation. Seven are systemic, being capsules, prolonged-release capsules, granules for oral suspension and a lipid suspension for injection, all for transplant rejection or lupus nephritis. The single topical row is a dermatology approval from 7 March 2003, an ointment marked not for children and indicated for dermatologists treating moderate to severe atopic dermatitis. That is a skin product, and our page on atopic dermatitis in dogs covers what it is actually for.

That regulatory gap matches the clinical literature exactly, which is the reassuring part. The peer-reviewed veterinary account says tacrolimus for canine dry eye is off-label and that it is generally compounded into an ophthalmic suspension rather than supplied as a finished licensed product, with formulations varying. So an Indian owner told their dog needs tacrolimus eye treatment is being offered a compounded preparation, which is a legitimate veterinary route and a different thing from a licensed product, and it is fair to ask the vet who is compounding it and to what specification.

The veterinary product, and what could not be established

The licensed veterinary eye ointment does not appear on its own manufacturer's Indian product list. MSD Animal Health sells a ciclosporin ophthalmic ointment indicated for the management of chronic keratoconjunctivitis sicca and chronic superficial keratitis in dogs, and it is the regulator-approved first-line product in the countries that license it Best LJ, Hendrix DVH. MSD Animal Health India's own Products index, Pharmaceuticals list and Companion Animals page were opened on 24 September 2026 and counted at 1,981, 849 and 292 words, and none of the three carries the words ciclosporin, cyclosporine, tacrolimus or ophthalmic.

State that carefully, because a company website is not a marketing authorisation database. What this establishes is that the product is not listed on the manufacturer's Indian site, not that no veterinary ciclosporin eye preparation can be obtained in India. Veterinary ophthalmologists in Indian metros do treat this disease, and an imported or compounded preparation is a normal route. What an owner can do is ask the treating vet which preparation they are prescribing, whether it is a licensed product or a compounded one, and where it is coming from.

What is unambiguous is that a ciclosporin eye drop is on an Indian pharmacy shelf today. A 3 ml ciclosporin eye drop marketed in India by Sun Pharmaceutical Industries was listed on 24 September 2026 at a maximum retail price printed on the page as ₹520 and a selling price of ₹479. Divided by 84.38 that is USD 6.16 and USD 5.68, and divided by 74 it is USD 7.03 and USD 6.47; neither figure lands on a round dollar, so this is an Indian price rather than a converted foreign list. It is a human product, it is prescription-only, and whether it is appropriate for a particular dog is a decision for that dog's veterinarian and nobody else.

What dry eye costs in India, from published government rate cards

Three Indian government veterinary hospitals publish their fee tables online, and this page reads the line items rather than quoting a range from a shopping blog. At ICAR-IVRI Izatnagar, registering a dog or cat costs Rs 30.00 in normal clinic hours, rising to Rs 200.00 after 12:30 PM and Rs 400.00 after 5:00 PM or on holidays, under the rates with effect from June 2024.

The line that matters most on this page is on the same rate card. IVRI's surgical table prices cherry eye at Rs 500.00 for a pet animal, alongside cataract surgery at Rs 600.00, enucleation of the eye at Rs 400.00, entropion or ectropion correction at Rs 250.00, corneal surgery at Rs 300.00 and tarsorrhaphy at Rs 200.00. A government teaching hospital therefore prices by name the operation that this page argues must be a repositioning rather than a removal. Every figure here was divided by 84.38 and by 74 and none of them lands on a round dollar amount.

The southern and eastern comparators are published too and they sit at different levels. At the Madras Veterinary College Teaching Hospital, TANUVAS, Chennai, small animal registration is Rs 100 and is valid for 7 days only, minor surgery is Rs 500, major surgery Rs 1,500, emergency surgery Rs 2,500, specialised surgery Rs 3,000 and haematology, biochemistry, urine or culture Rs 50 each. At the Veterinary Clinical Complex, Bihar Animal Sciences University, Patna, registering a dog or cat is Rs 200.00 in the outpatient window from 9:00 AM to 1:00 PM, valid for 10 days, and Rs 300.00 in the emergency window from 2:00 PM to 8:00 PM, valid for 5 days, with minor operations at Rs 500.00 and major operations at Rs 2,500.00 for a canine or feline patient.

Read the geography of those three fee tables before you use them as a national guide. ICAR-IVRI sits at Izatnagar in Bareilly, Uttar Pradesh, the Veterinary Clinical Complex is at Patna in Bihar, and Madras Veterinary College is at Chennai in Tamil Nadu. Those are the three government veterinary institutions whose published rate cards this site has been able to open and quote. No comparable published fee table was found for a municipal or state veterinary hospital in Delhi, Mumbai, Bengaluru, Hyderabad, Pune or Kolkata, and a private clinic in any of those cities sets its own prices, so an owner in Maharashtra or Karnataka should treat the figures above as the floor a public teaching hospital charges rather than as a quotation.

That geography also shapes who can run the test. All three published institutions are teaching hospitals attached to a veterinary university, which is where an ophthalmology service is most likely to exist in India, and two of the three, Patna and Chennai, price their consultations by a registration window rather than by speciality Tamil Nadu Veterinary and Animal Sciences…. A Schirmer strip needs no ophthalmologist, which is the practical point: it is a one-minute test any small-animal practice can run, and at ICAR-IVRI the visit that would carry it costs Rs 30.00.

Two things are missing from every one of those rate cards, and saying so is more useful than inventing a number. Not one of the three publishes a price for a Schirmer tear test. The strip does not appear as a line item at IVRI, at TANUVAS or at BASU, and no Indian source opened for this page prices it Bihar Animal Sciences University. Nor does any of them price a veterinary ophthalmology consultation separately from ordinary registration. What the rate cards do establish is the order of magnitude: the visit at which the test would be done costs Rs 30 to Rs 200 at a government teaching hospital, which is less than one bottle of the drops.

The recurring cost is the part owners underestimate, and it is the drops rather than the diagnosis. The PDSA page has a heading called Cost and publishes no figure in any currency, saying only that dry eye can become very expensive to treat because it usually requires lifelong treatment. The Indian arithmetic an owner can do for themselves is simpler: a bottle of the approved molecule has a maximum retail price of Rs 520, the treatment is indefinite, and the recheck is a Schirmer test at a clinic visit Best LJ, Hendrix DVH. Budget for the years, not for the first month. Our guide to adult dog care in India sets out the rest of the annual bill.

The Indian evidence that does not exist, and the search that shows it

No published Indian clinical series of canine dry eye was found, and here is exactly how that was tested. Two PubMed instruments were run through NCBI E-utilities on 24 September 2026. The title-and-abstract search, keratoconjunctivitis sicca or dry eye or KCS, and dog or dogs or canine or canines, and India[tiab], returned 0 records. The author-affiliation search, the same terms with India[ad], returned 2 records, and both were reviews from the Division of Surgery at ICAR-IVRI Izatnagar rather than Indian case series: one on mesenchymal stem cell therapy in veterinary ophthalmology, one on platelet-rich plasma in canine medicine.

Controls were run in the same session on the same instruments, so that absence is a finding about the literature rather than about the search. The identical query shape on canine parvovirus returned 40 records on India[tiab] and 84 records on India[ad], including Indian series from Gujarat, Mizoram, Odisha, Kolkata and Chennai. The instrument works. India publishes on canine disease in volume. It has simply not published a dry eye series, so every prevalence figure on this page is British and is labelled as such.

Indian law has not named this disease either, and the precise wording matters. The Prevention of Cruelty to Animals (Dog Breeding and Marketing) Rules, 2017 require in Second Schedule Part III rule 8 sub-clause (10) that breeding dogs shall have been tested for genetic defects, including hip dysplasia, progressive retinal atrophy, night blindness, hypothyroidism, entropion, ectropion and a list of jaw, tooth and cryptorchid faults. The words keratoconjunctivitis and dry eye appear zero times in the whole 14-page gazette, which extracts to 51,953 characters. Because the clause says including, the list is illustrative rather than exhaustive, so dry eye is unnamed rather than excluded. Two eyelid conformation faults that sit right beside it are named, and so is progressive retinal atrophy.

Living with a dog on lifelong eye treatment, and how to catch it early

A dog with treated dry eye lives a normal life, and the work is a routine rather than a crisis. Early and consistent management greatly improves comfort and long-term outcomes, and with treatment dogs with dry eye can live pain-free and happy People's Dispensary for Sick Animals. The two things that decide how well it goes are how early the gland was tested and whether the household keeps the treatment going on the days nothing looks wrong.

Book the recheck before you leave the clinic, because the schedule is published. Dogs diagnosed with dry eye should be evaluated every 6 to 12 months to assess the effect of treatment and the progression of the disease, and the first Schirmer recheck after starting tear stimulation is at about one month. That recheck is a number rather than an impression, which is the point of having a baseline.

Monitor the number rather than the look of the eye, and screen the breeds that need it before anything is wrong. VCA's owner page describes the disease, the signs and the treatment across 2,112 words and never tells an owner to screen a predisposed dog annually or what reading to monitor, while the VetCompass authors recommend exactly that, quantitative tear tests within yearly health examinations for predisposed breeds. Ask for the test, write down the millimetres, and monitor the trend year on year.

Handle the drops as a two-person household job rather than a one-person heroic act. Dogs with dry eye can be more sensitive to the sting of topical medicines, because an abnormal tear film cannot dilute them the way a normal one does, and that is worst with frequently applied preserved lubricants. Preservative-free artificial tears exist, they come in single-use ampoules, and owners generally find the ampoules inconvenient, which is an honest trade-off to discuss with your vet rather than a reason to stop.

Five habits carry most of the benefit, and none of them costs anything.

1. Ask for a Schirmer tear test at the annual visit from early adulthood if you own a predisposed breed, because that is the published clinical recommendation.
2. Write the millimetre reading in the vaccination card each year, since the trend matters more than any one number.
3. Keep the face clean and the hair clear of the cornea, because debris a healthy tear film would flush stays put on a dry one.
4. Report any new medicine to the eye vet, since sulfa derivatives and etodolac both have documented tear-suppressing effects with their own timelines.
5. Hold the dog at its breed weight, because dogs at or above the mean bodyweight for their breed and sex carried 1.25 times the odds of dry eye.

Prevention is breeding and surgery, not drops

There is no preventive drop, and the two real levers are conformation and the operating table. The VetCompass authors conclude that breed predisposition to dry eye suggests breeding strategies could aim to reduce extremes of facial conformation, and the RVC's own summary connects the flat-faced predisposition to the UK Brachycephalic Working Group's advice to stop and think before buying a flat-faced dog. The numbers behind that are the 3.63 times odds for brachycephalic against mesocephalic breeds and the 3.03 times odds for spaniels against non-spaniels.

The second lever is the one an individual owner controls completely. If your dog gets cherry eye, the gland goes back rather than out, and our cherry eye page covers how to have that conversation. If you are buying a puppy of a predisposed breed, ask what the parents' tear readings were, in the same way you would ask about hips; our guide to checking a dog breeder in India covers the rest of the paperwork.

Age is the last factor and it changes the watchfulness rather than the plan. The risk climbs steadily with age, from 3.7 times at 3 to under 6 years, to 11.3 times at 6 to under 9, to 18.9 times at 9 to under 12 and 29.4 times at 12 and over, all against dogs under 3. An older dog that starts producing morning gunk is not just getting old, and our guide to senior dog care in India puts that alongside the other checks that earn their place after eight.
