My dog's left eye keeps having more eye discharge than usual on & off for the last week. But only one eye. Do you think he may have an eye infection? Pet's info: Dog | Yorkshire Terrier | Male | unneutered | 6 years and 8 months old

Eye infection is one of the possibilities. However, conjunctivitis (viral or bacterial) usually affects both eyes. Excessive discharge from one eye can be related to trauma or scratch to the eyebulb, blocked up tear duct, third eyelid problem etc. If Rocco has had the discharge for the last week, you should take him to your local vet to have a full examination of the eye. That will show what is going on and the right treatment can be recommended.

Oh no, poor Rocco! Eyes are very delicate structures and can be damaged very easily. Excessive itching can quickly worsen an existing issue, such as a corneal ulcer, and can even lead to eye rupture in severe cases. Unfortunately, the only thing that you can do at home is make sure that Rocco is wearing an e-collar (cone) so that he does not damage his eye further. A vet will need to examine Rocco to determine the cause of his eye issue so that he can be appropriately treated. I hope that he feels betters soon!

This could be due to a corneal injury or ulcer. I always am concerned about eye problems and recommend an exam soon. The veterinarian will stain the eye to check for an ulcer and make sure there is nothing in the eye. Then depending on the findings they will prescribe eye medication. Generally when treated right away eye problems usually heal quickly. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Rocco.
