We use Heartguard Plus. Our vet also said the Revolution was not recommended for dogs only cats. He won't even sell it to a dog owner. But for those that only use Heartworm medication part of the year, don't you have to retest them and get the negative result back before you restart the meds? That is what our vet said if we ever lapsed in used the Heartguard . Being a week or so late is probably okay, but over that, you are supposed to retest is what I have been told by the vet.
I have heard of using the flea protection only part of the year, just not the Heartworm meds. |
