Recently, Nova has gotten a Hot Spot... My dogs have never gotten one before, so I had to look to a friend to find out what would be best to treat it. She told me Gold Bond Medicated Powder, and so far it's working WONDERFUL!
I know Nova doesn't have allergies, and he's recently been moved from the house to my new building next to the house for the doggies, so I'm thinking it's from a bug bite and a little added stress. But, wow, they are NASTY!
Good luck with Star!
