My Toy Fox Terrier had fleas terribly last year no matter how much frontline I put on her. My vet said the fleas have become resistant to the topical kind of flea prevention, and to use Comfortis. That took care of it almost right away. I don't know if Comfortis is okay for such a small dog or one with pancreatitis, though. If you do give it to them make sure to give it with a meal, or else they get sick. |
