My lil guy, Diesel, is a 7 mont old white bully with ongoing skin issues. He had a rash around his private area a few months ago, after a bloodtest, skin scraping and multiple follow up visits, he was put on antibiotics, topical cream and an anti-septic shampoo. Those bumps went away after this but now I've noticed the skin on his back becoming pinker and pinker and then a couple of days ago he obviously scratched so hard that he started bleeding. I don't know if this is the same outbreak that he had earlier, but I've treated it with the leftover cream & shampoo and it seems to have gotten a bit better. I was wondering if any of you have had this with your bullies. Any help/ advice/ suggestions would be very much appreciated. Picture is attached. Other changes before the rash appeared: we curently feed him cooked food "meaty muffin" - and we did change the main protien ingredient to beef (prior to that he was having turkey and chicken); he also had his rabies shot a couple of days before the rash started.
Many thanks in advance
