Bacterial blepharitis is a condition in which the eyelids become thick, reddened, inflamed, and encrusted. Mucuslike pus may adhere to the lids. Blepharitis in puppies occurs primarily in association with puppy strangles. In older dogs it can be associated with various skin diseases, including canine atopy, demodectic mange, autoimmune diseases, and hypothyroidism.
Staphylococcal blepharitis occurs in both puppies and adults. It is identified by small white pimples on the edges of the eyelids.
Treatment: Blepharitis is treated with oral and topical antibiotics. To remove adherent crusts, use a washcloth soaked in warm water as a daily compress over the eyelids. Three or four times a day, apply a topical ophthalmic ointment or solution containing neomycin, bacitracin, or polymyxin B. Your veterinarian may prescribe an ophthalmic ointment that contains corticosteroids.
Blepharitis is difficult to cure. Some dogs require long-term treatment. Dogs with chronic blepharitis should be checked for hypothyroidism. Any primary cause will need to be treated.
