A common eye infection in dogs that is caused by an inflammation of the conjunctiva. The conjunctiva is the coating that covers the eye and lining of the eyelid. When Conjunctivitis is present you will notice several symptoms on the dog such as rubbing at the eye, red and swollen eyes, and a discharge. Treatment involves several steps including flushing the eye, and possibly a prescription of both an anti-inflammatory eye medication and an antibiotic eye cream. In some cases surgery is required as well.
