You may be referring to "ProHeart 6". At one time it was removed from the market due to the number of adverse reactions. It is back on the market and is supposed to give 6 months of protection. It is a very risky choice. No matter what the vet says DO NOT LET YOUR DOG GET THIS INJECTION.
There really are some very heavy duty adverse reactions to this drug. Plus, it should not be used in dogs with allergies, including food allergies, atopic dermatitis, and flea allergy dermatitis. Since Labs and Goldens are over-represented in the population of dogs affected by Atopy, this really doesn't sound like the best choice of preventative for most of us.
Sadie has been on it for a year and a half. I spoke with her vet about it--risks and all--and I feel OK giving it to her.
Haley thinks Heartguard is a special treat and come running when I start to open it!
Charlie used to be on Sentinel and he wouldn't take the pill without me hiding it in something. When my new vet (we moved) switched him to Heartguard (they don't use Sentinel) I took one look at that pill and thought, "Oh my, how am I ever going to get him to take that!" But I just break it into pieces and like the others have said, he eats it right up like it is a treat!
