We have just aquired a dog in complicated circumstances. She has fleas. I took her to our vet this morning but they absolutely refused to give me anything without her records from her previous vet, and even if we can get them (it's complicated) they can't see her til after Easter. By which time we will be Flea Central. And she will have had another miserable itchy week. And she badly needs grooming- she's in a bit of a state. But presumably the groomer won't do her if she has fleas? Is there anything over the counter thwt works? Or does anyone have any clever ideas?
