Puppy With Green Eye Discharge After Visiting the Dog Park

Green-yellow discharge with red, watery eyes in a puppy who goes to the dog park could be allergies, irritation from dust or plant material, or an infection. If he also starts coughing, sneezing or seems unwell, kennel cough viruses and other infections are possible, and distemper is a concern in an unvaccinated puppy.

Please have him examined, especially if his vaccinations aren't complete. Benadryl may help allergies but won't treat infection. Keep him away from the dog park until he's checked.

Our page on conjunctivitis in dogs explains when pink eye can spread between dogs.
