I bought this product for my son's golden retriever, who has been suffering from hot spots on and off for a couple of years. After many expensive vet appointments and trying all kinds of OTC stuff, I purchased this for him to try. He is quite the skeptic and really didn't want to try it, but lo and behold the dog got a new hot spot and he finally used the product. It worked great and instantly helped the situation. I'm ordering another set to keep at my house in case he breaks out on my watch!
