I use Interceptor, not Heartgard; that is what my vet suggested when I got Sugar, my first bichon, almost 4 years back.

With the prescription meds, I don't find the online pricing much better either, and just get it from my vet. I do get the flea and tick stuff on line and the savings is there.

See this chart:

Interceptor covers many intestinal worms, so you most likely will never need to do a deworming.

Also, from things I have read, folks just don't seem to get good results with Revolution for dogs.

Revolution for cats is great, and I use that, also my vet's recommendation.

For my dogs, since I use a topical flea tick treatment to kill any that get on them, PLUS garlic to try and repel them in the first place, I really don't need a heartworm pill which will also address fleas. You will see on that chart, some of them do. It is just a matter of preference, I think, as to how you want to go about getting which parasites. Some are more prevalent in one area of the country than another, so that may alter a person's choice too.
