My RB Charmin had hot spots and she chewed her paws to the point where she would cause blisters the size of golf balls. My vet tried everything he could think but finally he told me to put her paw in hot water w/Epsom salts. That caused the blister to break and drain and the Epsom salts also helped it to heal. Of course, in the beginning, she fought me but once her paw was in the water, it felt soothing and she relaxed and left it there. Unfortunately, my RB Daisy got hot spots on her chest, abdomen and the top of her head. Not much help there, obviously. She lost the hair there and it never grew back. But the paws are doable. Hope this helps.
