I'd call the vet first but a thought that came to mind is if it is an irritation Baumex works great. It's made for a baby's bottom for diaper rash, but I use it for irritation when I shave my bikini and I also use it for burns, etc. It really really is wonderful and what I like about it is that it doesn't get hard and clumpy like destitin does. Best of luck. Elaine |
