So I had my guy in the yard with me today. This evening, while brushing him, I noticed 3-4 red spots on his belly/chest area. I called the after hours vet. The receptionist said they have been getting a lot of calls about these spots, which are caused by black flies. She asked me to email pictures for her to show the vet. I will call his regular vet in the morning. Meanwhile, has anyone had this issue before?
