Kanobi was treated for a skin condition with Clavamox for 14 days about 2 weeks prior to us adopting him. The scabs cleared up and he was fine. About 6 weeks ago I had him on NV Salmon and the bumps slowly started to return. I took him off the Salmon and put him on NV Rabbit thinking the bumps were an allergy response. He rotated to NV Beef and Lamb and the bumps remain. I treated him for 10 days with Clavamox and all but the bump on his head disappeared. The bump on his head is about the size of a nickel, gets crusty, bleeds and then scabs over but hasnt shrunk at all.
any ideas on what his condition might be prior to going to the vet?
I'll try to get a pic posted today.
