Fly Bite Dermatitis in dogs

Biting flies can attack the face and ears of dogs, sucking blood and inflicting painful bites over the tips or bent folds of the ears. These bites are typically scabbed and crusty black, and they bleed easily. German Shepherd Dogs and other breeds with erect ears are most susceptible.

Treatment: Keep the dog indoors during the day until the wounds are healed. If you are unable to do so, apply insect repellant to the ear tips. Products approved for use around horses’ eyes work well, such as Farnam’s Fly Off Ointment. Keep the ears clean and dry to discourage flies. Infected ear tips should be treated with a topical antibiotic ointment such as triple antibiotic.
