I found this bump on Buster yesterday and took him to the vet today. The vet thinks it's an allergic reaction to a spider bite or other insect bite. Buster got an antibiotic injection and some ointment to put on it. The bump is raised, very red, and feels crusted over on part of it. Is anyone familiar with a spider bite, does this look like one? This is my best picture, I took a lot of them but just as I think I have a good picture, he moves.
