Any opinions on Interceptor heartworm prevention?

Question

My vet chose to give me this instead of Heartguard. My dogs have never been on anything but this, however I never really asked her why she chose this instead of Heartguard, which I have heard more about. Any experiences, good or bad, with either?

Answer 1

Actually, Interceptor prevents more than just heartworms. It's an internally-taken flea and tick repellent, too, and after 3-4 months, the dog will not need to take external repellents such as Frontline. It can be difficult to make the dog actually take the medicine, but crushing it and applying a liberal amount of baloney usually makes the job easier.
My dogs have been on both medicines, and did well on both. I find that Interceptor is a bit more convenient in the long run. There should be no difficulty in transition, medically speaking, since the heartworm preventative is basically the same.

Answer 2

Interceptor works well for prevention of heartworms.Your dog needs to be on some type of preventative.
It is more of a hard pill than a soft chew and some dogs do not take it as well as the soft chews.
I think some vets just prefer it to the Heartgaurd. It is the same chemicals just slightly different packageing.

Answer 3

Here's something I've read....

There have been many reports of dogs having very bad reactions to both Heartguard and Interceptor. Giving ones dog doses of poison month after month to kill something which possibly isn't there doesn't make an awful lot of sense to me.

Answer 4

We've used both - never noticed any difference.
