Black fly bites are most commonly seen on the abdomen or the inside of the legs, where hair is sparse. They range in color from pink to bright red to almost purple. They are often mistaken for tick bites, due to the “bulls eye” appearance they generally have. Yet, unlike in people, tick bites don’t cause that “bulls eye” effect in dogs.
What should you do if you find a black fly bite on your dog?
Just keep an eye on it! It should resolve on its own in a few days. Treatment is not usually necessary, as long as there is no excessive itching, pain, or swelling.
If you are unsure reach out to your veterinarian who can guide you further.
