Excessive tearing can be caused by many variables, including food, mineral content of water, allergies, sickness, clogged tear ducts, teething and even fleas.
Just like humans, it’s normal for your pet’s eyes to stay moistened with tears; however, your pet’s tears collect in the fur surrounding the eyes and the area becomes a breeding ground for bacteria thus causing stains. Left untreated, it can lead to itchy irritation and even infection.
