Marley has an auto immune disease, not exactly sure which one, no blood work done yet. He has had acne spots before that I was able to clear up at home using hebiclense. I noticed the other day that he has a big (bout the size of a dime) patch of acne under his chin. I've been cleaning it for about 4 days now and it is about half the original size, but it still looks pretty nasty. Do you think this is something the vet needs to care for?? I wanted a vet visit to be last resort becuse last time he got shots that make him mopey for 2 weeks!!! and it cost me $100.00!! How long should I give it to clear up?? Is a week too long? He doesn't scratch it or anything, but he doesn't like me to clean it...Im sure it hurts to be touched. TIA
