I found a strange bump/boil looking thing on my 4mo GSD puppy today. He had a rash (I posted about that a few days ago) and changing his food has taken that rash almost completely away (THANK GOD!). This spot was on his front right leg when he had his rash. The vet did not think anything really out of the ordinary of it. He is on an antibiotic, so if its bacterial it should go away, but we have no idea what it is. If anyone has any knowledge of what this could be that would be greatly appreciated!
