I'm honestly clueless... Also, to those who only give a heartworm preventative during the warmer months, how do you do this? I mean, once you start giving the heartworm preventative to them and then you stop for so long (for so many months), don't you have to have them tested for Heartworms to be sure that they don't have them before you start them back on the preventative again? I have always heard that this was necessary after they had been off the preventative as if they WERE to have Heartworms when you started them back on the preventative, it could kill them. |
Some are hesitant to use it because it is a pesticide and can (in rare instances) cause death.
Sometimes vets make their clients test even if the dog is on it year-round since nothing is 100%.
We use Interceptor. Heartworms are way too dangerous to not protect against. I'd rather give her the piill that she does well on then give her arsenic injections if she were to get them.
There are some thtat I wouldn't even consider using though because there are too many reports that they are ineffective. Revolution is one of them.
