Conjunctivitis in dogs is an inflammation of the eyelid lining. It is one of the most common eye infections in dogs. It is usually accompanied by a discharge from the eye. The discharge can be clear or watery. It is called serous conjunctivitis. It can be caused by misdirected hairs, foreign bodies, physical irritants such as wind and various allergens. Allergies are usually the major cause.
If the discharge is yellow or green looks like pus and has a thick, tenacious appearance suggest a bacterial problem call parulent conjunctivitis.
If the problem persist for a long time it can become chronic. Your vet may have to do a culture to identify the bacteria to determine the most effective antibiotic to use for treatment. Chronic dog eye infections are difficult to clear up. It can affect the tearing system of the eye. Red eyes in dogs can be a sign of infection. The primary approach to this problem is to cleanse the eye often and use a specific antibiotic determined by cultures to heal the eye.
