I haven't used it but I have heard that it doesn't protect againist heartworms as well as the heartworm pills. My roommate is doing her clinicals in vet school and the vets there will not recommend Revolution. I have no idea if this is true or not, but just thought I would pass it along. I would like to use it because I hate drenching my 2 lb baby with enough flea and tick meds for a 22lb dog, but my vet, and other vets around my area, do not recommend it, or even sell it... |
