scabies are under the skin and my vet said the pet is give 3 shots , one per week . And a flea bath or cream will not kill scabies on a dog . I knew someone that got scabies and they gave their dog a flea bath , which was a waste of time and money. The shots for scabies are $10 a shot at my vet , I asked about the scabies shots because a coyote was coming right into yard and a lot of coyotes had to be killed one year because they had scabies .
