These spots appeared on Loki (my darling sweety that just turned a year on July 4th, true American Pitbull) at about 8:00 PM on Sunday, July 8th. I gave him 25mg of Diphenhydramine HCl (generic Benadryl) at about 9:30 PM thinking that it was just an allergic reaction but they have since gotten worse and spread. If anyone has seen these before I would appreciate any advice you have. I have scheduled a vet appointment but the next available appointment was not until wednesday so any help I can receive on how to relieve/eliminate these protrusions would be so greatly appreciated.
