My dog's hot spot problem was getting to the point where we were going to have to invest in another vet visit (last one for this was over $200!) That was last spring about this time and we wanted to avoid the expense again if at all possible. I was using the hydrocortizone lotion and benedryl and it was improving but I ordered Missing Link anyway just to try it.

Well, by the time it came, he had stopped scratching completely and the sores are healing. Sooooo - I guess it doesn't have to work - you just have to buy it. I am putting the package in the freezer unopened until he has another problem with hot spots. Hopefully it won't be until next spring.

I decided against Dinovite because of negative comments and the price.
