Abstract
Fly-bite dermatitis was diagnosed in 35 dogs, accounting for 0.4% of the canine dermatology cases and 0.1% of the canine hospital population over an 11-year period. Labrador retrievers appeared to be over-represented. Three different clinical presentations were recognized, and may be associated with the bites of Simulium spp. (black flies), Chrysops spp. (deer flies), or Stomoxys calcitrans (stable flies). The dermatoses occur during fly season in dogs that go outdoors.
