I tried to join Photobucket, but when I went to download pics, it just said downloading 0%, and never moved! So I dont' think I can. It started out as a flesh colored bump, then rapidly turned into a scab, so I'm hoping it's either a food allergy or medication allergy. He is acting normal, not in pain or anything. I'll know more after I take him to the vet on 6/4. Thanks for your concern.
