Is HeartGuard the best heartworm prevention medicine?

Answer by  my2cents (264)

Your vet can recommend the best brand for your pet. Different sizes of pet require different dosages etc, and only a vet can give specific advice. As I understand all of the medicines contain the same drug, dosage is by size of pet, not higher in one brand.

HeartGuard is an okay brand, but the best ones are quite expensive and can only be purchased from a practicing veterinarian. Most over the counter heart worm preventions do more bad than good. They are very harsh treatments and take a toll on the immune systems of dogs. Before starting any treatment, always talk to a veterinarian.

As far as which is better then the other, some animals work better with one medicine over another. Same with your vet. They may like one brand over some others.

Yes it isn't a cure and if the animal already has them it will be a process to get through but as far as prevention yes that's the best your money can buy.
