While eye discharges are pretty common among canines, it is important to know exactly when the problem is indicative of an underlying medical condition of a more serious magnitude. In order to ensure timely corrective action, as a pet parent you must learn to understand the various types of eye discharges in dogs and what they actually indicate.Clear, Watery Discharge
While tears play a vital role in hydrating the eye and keeping the cornea nourished with oxygen, excessively watery eyes of your furry little friend might be associated with a variety of medical conditions ranging from common allergies to more serious anatomical abnormalities. Excessive watering in a dog's eye when exposed to excessive dust irritants, pollutants, pollens or smoke is known as epiphora.. However, If your dog experiences constant redness or inflammation in his eyes and appears to be in pain or acute discomfort, you must consult the vet immediately to rule out any chances of any corneal wounds or glaucoma.Mucus With Yellow Pus Discharge
If you notice excessive epiphora along with mucus and pus discharge in your dog’s eyes, it might indicate an affliction of conjunctivitis that has inflamed the inner lining of your dog’s eyes. Among the various factors that can cause conjunctivitis in dogs, tumors, distemper, dry eye, presence of foreign matter, tear duct conditions, birth defects and injuries are the commonest. Your vet will first examine your dog’s condition and then prescribe a suitable line of treatment after ascertaining the underlying cause for the discharge.Sticky And Tenacious Discharge
If your four-legged friend has developed a sticky eye that constantly discharges a thick mucus like substance, he might be suffering from a condition called a canine dry eye. A dry eye occurs when the dog’s tear glands are unable to produce sufficient quantities of tears for keeping the eye cleansed and hydrated. When left untreated, dry eyes can advance to more serious eye infections and eye ulcers due to excessive scratching or chaffing of the eye in absence of enough lubrication.Glaucoma Associated Discharge
Some dog breeds such as Cocker Spaniels, Chow Chows and Poodles are genetically more predisposed to developing glaucoma at some point in their lives. Glaucoma may be classified into two basic categories including primary glaucoma and secondary glaucoma. Common symptoms of glaucoma other than excessive eye discharge include dilated pupils, clouded eyes, bulging of the eyes, sensation of high pressure on the eyes, abnormal blinking and loss of vision. If you notice any of these symptoms in your dog, it might be time for you to pay a visit to your dog’s vet.Reddish Brown Stain Like Discharge
Some light-colored breeds are susceptible to developing reddish brown pigmentation in their fur just beneath the inner eye corners. The reason behind this pigmentation is the presence of a pigment known as porphyrin in the dog tears that transforms into a reddish-brown colour upon prolonged exposure to the atmospheric air. Typically, this condition is a cosmetic concern and does not indicate any serious medical issue.
