thank you all for your help adnd yes ginger899 kerosene was a bad idea lol
Whatever originally caused the irritation is hard to say. But the kerosene could have caused some burning of the skin, and I think by far the best option is to take him to the vet.
It may be Benadryl cream would help. But take him to the vet anyway.
I remember when I was a child, people used to swear by Coal Tar soap for clearing skin problems. I hated the smell of it! It never worked anyway! I suppose that is related to your fiance's uncle's idea that kerosene might help.....but bad idea I think. Never mind, what's done is done. Now that skin needs to get some right medication and heal.
My chow did the same thing.And my vet suggested that we take beef out of his diet. After we did that and about a week of antibiotics we had no problem. It might be a beef allergy. To be on the safe side take him to the vet. But give that a try.
