Q: Our dog (or cat) frequently has yellow or green or dry "stuff" at the corners of her eyes. Is this a problem and do we need to do anything about it?

A: This is a common occurrence, especially in the spring and summer. Most of the time the little duct that drains tears (the nasolacrimal duct) from the eye has become clogged secondary to allergies.

This means tears run into the corner of the eye and pool there on the skin.

This is usually not a problem for the pet, but there are some instances that can mean medical attention is needed.

Corneal ulcers, ocular foreign bodies and severe allergic reactions are a few of the things that do need treatment.

The safe plan is to have your pet checked out if you have never seen this happen before. If your veterinarian does determine that mild allergies are the cause, he or she will discuss long-term management options with you.

If there is something more serious happening, you will be thankful you came in!
