Dry eye syndrome, or keratoconjunctivitis sicca (KCS), affects many dogs. It happens when there’s not enough tear production. This can make dogs uncomfortable and may lead to vision issues.1
Several things can cause dry eye syndrome in dogs. Immune system issues are a main cause, leading to less tear production. Other causes include infections, certain medicines, genetics, and more.2
This condition usually shows up in middle-aged to older dogs. But, it can happen at any age. Certain dog breeds like the American Cocker Spaniel and Cavalier King Charles Spaniel are more likely to get it.1
To diagnose dry eye syndrome, vets use a special test called the Schirmer tear test (STT). It measures how much tear a dog produces. Normal tear production is over 15 millimeters per minute. Less than 10 millimeters means dry eye syndrome.2
The goal of treating dry eye syndrome is to boost tear production and protect the eye’s surface. Doctors often prescribe medications like cyclosporine and tacrolimus. These help make more tears. Keeping the eye moist is also key to treatment.1
In severe cases, surgery might be an option. But it’s not a complete fix and can lead to long-term problems. Serious cases of dry eye can cause major issues. These include ulcers, infections, and even blindness if not treated.3
With the right treatment and ongoing care, many dogs with dry eye syndrome can live without pain. Yet, it’s important to catch it early. Late-diagnosed dogs with a lot of eye damage may not see as well. Seeing the vet regularly and following the treatment plan are key.1
Key Takeaways:
- Dry eye syndrome in dogs is common and results from not making enough tears. It can be uncomfortable and affect sight.1
- Dry eye can stem from immune problems, infections, meds, genetics, and more. Some dog breeds are at higher risk.1
- The Schirmer tear test is a key diagnostic tool for dry eye in dogs.2
- Treatment may involve medications to increase tear production, tear replacement, and more. Surgery might be an option for severe cases.1
- Correct treatment and regular care can offer a pain-free life for dogs with dry eye. Full vision recovery might not be possible in all cases, though. Regular vet visits are crucial.1
What is Keratoconjunctivitis Sicca?
Keratoconjunctivitis sicca (KCS), also known as dry eye syndrome, is a common eye problem in dogs. It causes inflammation of the cornea due to not enough tears. Tears are vital for keeping the eye moist, clearing out dirt, and preventing infections. The tear film is made of mucus, fat, and water. A disruption in tear production leads to dry eye. In dogs, KCS is often caused by immune system disorders that damage tear-making glands. Other causes include infections, certain medications, hypothyroidism, or nerve damage.1
Dogs with dry eye syndrome may have painful, red eyes and thick mucoid discharge. They might squint, blink a lot, and get corneal ulcers. It’s more common in certain breeds like Cavalier King Charles Spaniels, English Bulldogs, and others. This suggests a genetic link to the condition.4
To diagnose KCS, vets use the Schirmer tear test and corneal staining. This shows how severe the condition is. Treatment may involve medication to boost tear production and protect the cornea. Surgery to move the salivary duct might be an option, but it has risks. Dogs with KCS need lifelong care and regular vet visits to avoid corneal scarring.1
Research has helped us understand more about tears in dogs and how to manage KCS. Studies have shown that age, sex, weight, and time of day can affect tear production. They’ve also looked at causes and treatments for tear imbalances. Some work has focused on the effects of canine distemper virus on dry eye. Others have explored treatments like cyclosporine for managing KCS. A large review of cases has tracked the disease’s trends.5
Knowing about KCS’s causes, signs, and treatments helps pet owners care for their dogs. Early diagnosis and proper management mean dogs with dry eye can have a comfortable life. They can keep their eyes healthy with the right treatment.4

Common Causes of Dry Eye in Dogs
Dry eye in dogs, also known as keratoconjunctivitis sicca (KCS), has many causes. It’s crucial to find these causes for effective treatment.
Breed Predisposition
Some dog breeds are more prone to develop KCS. These include the American Cocker Spaniel, Bloodhound, and many others1.
Immune-Mediated Diseases
Autoimmune diseases are a leading cause of dry eye. They attack and damage tear-producing glands, reducing tear production6.
Infections
Infections like conjunctivitis can lead to dry eye by damaging the tear film. This results in less tear production and dryness6.
Medications
Some medications, especially sulfonamide antibiotics, are linked to dry eye. They disrupt the tear film’s balance6.
Hypothyroidism
Lack of thyroid hormone can cause dryness in dogs. It replaces normal tears with mucus, leading to dry eyes6.
Nerve Damage
Nerve damage can affect tear gland function. This leads to reduced tear production and dry eyes6.
Some breeds are more at risk of dry eye. Knowing the causes helps in treating it. Addressing these causes can enhance a pet’s life.
Breeds Predisposed to Dry Eye
| Breed | Breed | Breed |
|---|---|---|
| American Cocker Spaniel | Bloodhound | Boston Terrier |
| Cavalier King Charles Spaniel | English Bulldog | English Springer Spaniel |
| Lhasa Apso | Miniature Schnauzer | Pekingese |
| Pug | Samoyed | Shih Tzu |
| West Highland White Terrier | Yorkshire Terrier |
Clinical Signs of Dry Eye in Dogs
Dry eye syndrome, also known as keratoconjunctivitis sicca (KCS), shows many signs in dogs. Spotting these signs early is key for the right treatment. Look for these symptoms in your dog’s eyes to catch this condition early.
Dogs with dry eye tend to have red and sore eyes. This condition hurts and makes them uncomfortable. When their eyes don’t make enough tears, it leads to soreness and redness.
Another sign is a thick discharge from the eyes. With less tear production, the discharge turns thick and yellowish. This can block their vision and bother them.
Dry eye can also cause corneal ulceration. The cornea, the eye’s clear cover, needs tears to stay unharmed. Without enough tears, it gets damaged easily. This damage can hurt the dog and even scar the cornea, affecting its sight.
There are also other symptoms of dry eye in dogs. They might get eye injuries, ulcers, or conjunctivitis often. It’s common for both eyes to get the condition, but one may be worse than the other.
If you see any signs of dry eye in your dog, don’t ignore them. Early treatment can ease the discomfort and prevent more problems. Talk to a vet if you notice these symptoms for a check-up and treatment advice.

Diagnosis of Dry Eye in Dogs
Diagnosis of dry eye in dogs includes their medical history, looking at symptoms, and testing tear production. The Schirmer tear test (STT)2 is commonly used to measure tear film in one minute. A special paper strip gets placed under the dog’s lower eyelid.
The moisture the strip absorbs tells us if the dog’s tear production is enough or if they have dry eye. Other tests might involve corneal staining2 to look for any corneal ulcers or imperfections, and checking the tear ducts to ensure they drain properly2.
Treatment Options for Dry Eye in Dogs
Treatment for dry eye syndrome in dogs focuses on boosting tear production. It also replaces the tear film to shield the cornea. There are several methods to handle this issue and make life better for your pet.
Tear Production Stimulants
Treatment often involves tear production stimulants like cyclosporine and tacrolimus. These meds are key in increasing tear production for a healthier eye. They’re mostly put directly onto the dog’s eye. Cyclosporine has been proven to really help boost tear production and lessen eye discomfort. [2]
Tear Film Replacement
Replacing the tear film is critical for dealing with dry eye in dogs. We use artificial tears and ointments to substitute the missing tear film. This keeps the cornea moist and healthy. It also lessens pain, cuts down on inflammation, and stops more issues. Combining tear film replacement with stimulants gives the best effect. The application depends on the dog’s needs and the vet’s advice. [2]
Antibiotics and Anti-inflammatory Medications
If there’s an infection or swelling, your dog might need antibiotics or anti-inflammation medicine. These help fight infections and reduce eye swelling for a smoother healing. They’re often used alongside other treatments. Be sure to stick to the vet’s directions on how much and how often to give these medicines. [2]
Warm Compresses and Eye Hygiene
Good eye care also helps manage dry eye in dogs. Using warm compresses can boost tear production and soothe the eyes. Just press a warm, damp cloth to your dog’s eyes gently. Avoid anything that might irritate the eyes further. For the best care tips, talk to your vet. [2]
Staying on top of treatment is vital for handling dry eye in dogs. Your vet might change the treatment based on how your dog is doing. With the right care, many dogs with dry eye get much better and have a happier life.
Surgical Options for Dry Eye in Dogs
In cases where giving medicine is not an option, surgery might be a choice for dry eye in dogs. One surgery involves moving the salivary duct to wet the eyes with saliva. This helps soothe dryness and discomfort by aiming to boost tear production and eye moisture.
This surgical move is often a last choice after other treatments have not worked. It is done by eye surgery experts for animals. They redirect a part of the salivary duct to help saliva reach the eye, making up for missing tears.
But, choosing this surgery comes with big risks and possible problems. It should only be picked after trying all other options, with advice from a vet expert.
Reference1: The most common cause of dry eye in dogs is immune diseases. Surgery might be an option if medication cannot be used, moving the salivary duct to wet the eyes.
If your dog’s dry eye is really bad and other treatments haven’t helped enough, your vet might suggest this surgery. It’s crucial to talk thoroughly with your vet about the surgery’s risks and benefits.
Remember, moving the salivary duct is a complex procedure. It needs a surgeon skilled in animal eye surgeries. It’s very important to find a qualified professional for your pet’s care and advice.
Before thinking about surgery for your dog’s dry eye, look into all less invasive options. New drugs can stimulate tear production and have greatly helped dogs with dry eye. Many can live without pain with ongoing treatment.
Talking to your vet is key to finding the best treatment for your dog. They will look at how bad the dry eye is, your dog’s health, and the surgery’s risks and benefits. Together, you’ll choose what’s best for your dog’s health and happiness.
Prognosis for Dogs with Dry Eye
Dry eye syndrome is common in dogs and needs lifelong care. With the right treatment, many dogs live comfortably. But, severe cases might not see full vision recovery due to corneal scars3. It’s essential to keep an eye on the dog to protect their vision and comfort3. Following the vet’s advice is key for good results3.
Early diagnosis and treatment greatly affect the prognosis for dogs with dry eye7. Starting treatment early is crucial7. Without it, dogs may develop corneal ulcers, needing serious treatment7. Tear stimulant medications are vital for keeping tear production up and avoiding further issues7. Life-long care, including regular medicine, is necessary7. It’s vital for dog owners to stick to the treatment plan7.
If medical treatment doesn’t work, surgery like parotid duct transposition might be an option37. Note that surgery doesn’t cure the condition and can bring long-term problems3. Discussing surgical options should be done with a specialized vet3.
Summary:
Treating dry eye syndrome in dogs well means they can likely keep their vision and stay comfortable. This includes using tear stimulant medications for life. It’s crucial to get an early diagnosis and to follow the vet’s treatment plan closely. Surgery might be considered if nothing else works. But, it’s not a cure and comes with its own risks. Always talk to a vet expert when considering surgery.

Conclusion
Dry eye syndrome is a common but painful condition in dogs. It can be managed well with the right care. Doctors use medicines to boost tear production and replace tear film.
Other treatments fight infections and reduce inflammation. Checking in with the vet regularly helps keep your dog’s eyes healthy.
Research shows dogs with certain test results have a good chance of getting better. Dogs with an STT score of 2-14 mm/min often return to normal tear levels.2But, dogs scoring 0-1 mm/min might not fully recover. Lower scores mean a tough road to recovery.2The Schirmer Tear Test is how vets find this syndrome. A reading under 10 mm means dry eye is likely.2Some breeds, like Yorkshire terriers, are born more likely to get it. This is due to their genes.2Organizations like Bowie Barks Adoptions are helping. They’ve had thousands apply to rescue such dogs last year.2There are treatments like ophthalmic cyclosporine and antibiotics. Some dogs might even need surgery.2It’s key to note, some treatments can temporarily stop tear production. This includes anesthesia or atropine.2Recently, up to 1.5% of North American dogs got dry eye. Dogs get it more often than cats.8Most cases in dogs stem from immune issues. Especially an autoimmune response.8Certain dogs, like spaniels and bulldogs, are at higher risk. It seems to be in their DNA.8Diseases like diabetes can also lessen tear gland function. This leads to dry eye in dogs.8Infections and some viral illnesses can trigger dry eye by damaging the tear gland. And, damage to certain nerves can also cause dry eye.8In summary, it’s crucial to spot dry eye symptoms early in dogs. Quick action and treatment can make a huge difference. Regular vet visits, plus the right medicines and care, are essential. By teaming up with their vet, dog owners can ease their pet’s discomfort and keep them happy and healthy.
