It cost me $200 to test Max (22 lb dachshund). Our vet had no idea what was causing Max trouble either and that's why he suggested the test. It was kind of a last ditch effort for us. We had tried all the other things and nothing had helped.

The $200 got us the test and the first set of medicine. There were two vials in the kit. One was a higher dose to desensitize him and the other is a maintenance dose. We did all this last spring and I still haven't had to refill the maintenance dose yet.
