Conjunctivitis is one of the most common eye conditions in dogs. It involves inflammation of the conjunctiva, the membrane that lines the inside of the eyelids and the surface of the eye. Although it rarely endangers the animal's life, it requires veterinary attention to avoid complications.
Types of conjunctivitis in dogs
There are several types depending on the cause:
- Bacterial: caused by bacteria such as Staphylococcus or Streptococcus. Produces purulent yellowish or greenish discharge.
- Viral: associated with diseases such as distemper or infectious canine hepatitis.
- Allergic: related to environmental allergens (dust, grass, mites). Causes intense itching and watery discharge.
- From irritants: dust, smoke, chemicals or foreign bodies.
- Dry (keratoconjunctivitis sicca - KCS): insufficient tear production, very common in some breeds.
Symptoms of canine conjunctivitis
- Redness and excessive tearing
- Eye discharge (clear, yellowish or greenish)
- Abundant eye crust, especially in the morning
- The dog rubs its eyes with its paws
- Swollen eyelids
- Photophobia (sensitivity to light)
Most predisposed breeds
Some breeds are more prone to conjunctivitis due to their anatomical characteristics. The Cocker Spaniel, the English Bulldog, the Labrador Retriever and the Toy Poodle are particularly vulnerable. Brachycephalic breeds (short snout) often develop chronic forms due to the anatomy of their eyes.
Treatment
Treatment depends on the cause. The vet may prescribe antibiotic eye drops or ointments, antihistamines or anti-inflammatories depending on the type of conjunctivitis. Regular eye cleaning with specific products is important to maintain ocular hygiene.

When to see the vet?
Consult the vet if the discharge is abundant and purulent, if the eye is closed or very swollen, if symptoms persist for more than 48 hours or if the dog persistently rubs its eyes, as it could injure the cornea.
