Sometimes, the watery discharge or yellow-green pus from the eyes is a sign of conjunctivitis. It is an inflammation in the border of your pet’s eyes. Conjunctivitis can be caused by various factors such as injury to the eye, severe allergies, tear duct obstruction, birth defects, dry eyes, tumors, or a foreign matter could be lodged in his eye. To determine whether your pet is suffering from conjunctivitis or not you should also look for signs like red eyes, increased frequency of a blinking eye, inflammation, crusty eyes, squinting eyes, keeping eyes closed or pawing at the eyes.

Treatment for conjunctivitis

The best way to treat the condition is by finding what caused it in the first place. This elimination process is somewhat depending on the cause of conjunctivitis. It might include pain relief medication which reduces the irritation and soothes the area. However, to clear the infection, antibiotics or saline washes can be used. If allergies are the ultimate cause, then antihistamines and other medications might be the solution. All of these scenarios require you to consult with your local veterinarian to resolve and treat.

Epiphora (excessive tearing)

It causes watery and teary eyes in dogs. Other signs include stains on the skin and also smelly skin or fur. In some cases, it also causes infection of the skin. This can be the outcome of various conditions such as allergies, inflammation, abnormal eyelashes, corneal ulcers, etc. If the medications do not work, then it might be eye pain or a tumor.


The treatment is based on the cause. The conventional treatment includes using topical antibiotics, to treat tear duct inflammation. Steroids can be used if the cause is cornea damage followed by topical medications and antibiotics to clear up the symptoms. In cases of ulcers, abnormal eyelashes or duct obstruction, surgery is a reliable option.

Dry eye

Dry eye occurs when the eyes are not able to produce sufficient eye-cleansing tears. This leads to a sticky eye discharge in dogs followed by inflammation. The eye discharge could be the result of injury, a hit on the head where the tear-producing gland is located, distemper, or the immune system is working against the tear gland tissue. If the eyes are infected, then your pooch might be suffering from severe pain and inflammation in the eyes. Ulcers on the surface of the eyes should also be taken seriously as the absence of the lubricating tears leads to scratching on the eyes by eyelids. It is painful for your pet to open and close their eyes in this situation.


The treatment for this condition depends on its severity. If the eyes are mildly dry then artificial tears can be used for weeks. If the infection is in the second stage, then antibiotic eyedrops can be used to reduce the pain. Surgery is also an option when the condition is severe and immunosuppressant drugs are also helpful in developing a stronger immune system.


There are few visible symptoms of glaucoma, such as bulging in the affected eyes. If both the eyes are affected, then it can be seen in both eyes. Cloudy eyes are also a sign of glaucoma, which is mainly caused when the eyes are under excessive pressure. This ocular pressure can be reduced using medication, but in many cases, surgery is the best option.

Is it your dog’s breed that makes it more prone to eye discharge?

Dogs of certain breeds are at higher risk of developing eye-related conditions. Dogs with a flat face, such as pugs, boxers, bulldogs, and Pekingese are at higher risk of suffering from eye discharge. These dogs have shallower eye sockets and protruding eyes.

Eyelids in dogs that roll inward that are brachycephalic breeds are also prone to developing eye discharge. These dogs have more prominent eyes and the lashes cause a significant level of irritation in their eyes. Some dogs are not able to close their eyes entirely and for this surgery would be the best option.

Dogs that have loose facial skin are also at higher risk of developing this condition. Such dog breeds are Beagles, Bloodhounds, Saint Bernards, etc. They are also more prone to the disease called” cherry eye,” where the gland in the eye falls from its position. Some vets offer antibiotics, but surgery is required to solve the problem.

These are the main reasons that cause eye discharge in dogs. Eye-related problems in dogs and cats are also caused by brain injury or nerve injury. There might be other severe problems which could be the root cause. It is crucial for you to ask your vet to determine the root cause of any eye discharge in your pet and give treatment accordingly.
