Watery Eyes and Excessive Tearing

Determine whether your dogs tears are normal or if there is an underlying problem.

There are 2 types of tears: baseline tears and reflex tears. Baseline tears are produced constantly and keeps the eyes lubricated. Reflex tears are produced when there is an infection, allergies, or irritant in the eyes.

Read below for the symptoms to watch out for and know if your dog’s eyes are producing more tears than normal, and schedule a trip to the vet for check up.

Symptoms of excessive tearing

Animals with excessive tearing have wet or moist fur below their eyes and may have other findings based on the underlying problem. If the tearing is chronic, animals develop a reddish brown stain below their eyes. The area may also be moist and their skin may become red and irritated.

What causes excessive tearing?

1. Increased production

Increased production of reflex tears may occur at higher volumes to “flush” an irritant away. In some animals, excessive tearing can be due to this increased reflex tearing.

2. Impaired drainage

When excessive tearing is caused by impaired drainage, it is called epiphora. Tears normally drain via the tear ducts and ultimately empty into the nose. If there is a blockage anywhere along the course, tears will overflow.


So why does the lacrimal drainage system become blocked? Blockage can occur due to trauma, inflammation, medications, and rarely tumors. In certain breeds of cats and dogs, the problem is their anatomy. Breeds with flat faces (brachiocephalic) such as Boxers, Bulldogs, and Pugs, can have epiphora due to their flattened facial anatomy.
