We have never had a flea issue in our house before, but this year seems to be crazy with fleas. My daughter's dog is having a flea allergy reaction. She's scratching herself bloody. We are keeping it clean, and tried to cover it with gauze, but she goes insane. It hurts her so much. We muzzled her and tried again, but she hurts herself by pulling and twisting away. Every time it starts to heal she scratches again, and we can't cover it. My daughter gives her dog benadril, and that seems to help, but we can only give her one a day as she's a small dog. Any advice would be greatly apprecaited.
