I have found that the best way to cure (and I do mean CURE) hot spots in dogs is in the form of a poultice, rather than a liquid. Liquids can be too easily licked off, and once they dry, they lose effectiveness. I had dogs with hot spots, came up with a poultice, never used a cone, and they stopped worrying it immediately. It also went from most of a toy poodle's back to a 1/2 inch strand left in two applications, over 4 days. PLEASE consider the comfort of your animal... liquids sting, poultices soothe!
