Anyone ever experience any type of skin sores with their dog? Ace has these sores popping up on his chest area, belly and crotch. I thought it was flea reaction but I put flea medication on him and they arent going away. They are now causing him to limp because they are bothering him. I first thought he hurt his leg but he shows no sign of discomfort on any legs when i move them or put pressure on them. So im guessing these sores in his "armpit" area are causing discomfort. I think im gonna go ahead and get him an appointment for the doc on Monday or Tuesday cause it seems to be getting worse. Anyone ever seen anything like this with their dog?
