One time my cat got fleas really bad and the vet gave her a pill that killed them all within hours of taking it. It was a long time ago, I wish I could remember the name of it. I know that it is for dogs too. That might be a solution to your problem when it's time to go home, but I don't think it would help you during your stay. I'm sorry your not enjoying your vacation! At least your dogs are having fun
