Veterinary Physiologist Interview Question:

Explain me why do my dog's eyes always have discharge/tear stains?

Submitted by: Muhammad

A small amount of clear discharge from the eyes can be normal in some dogs, but this normally does not lead to staining of the hair below the eyes. If your dog has excessive tearing there may be a problem with the eyelids or the eyeball itself. There are many different causes of excess discharge and your dog may need a full eye exam from your veterinarian to determine the cause.
