I use Interceptor for heartworm, but all heartworm meds work the same, it's just a matter of preference. I used to be a vet assistant and Interceptor is the only thing my vet sells. I just got used to using that.

Frontline and Advantage only prevent fleas, where Advantix prevent fleas, ticks, and mosquitos. I have heard bad things about Advantix, such as lots of side effects, loss of hair, and someone at my dog training club, lost her dog because of it. This has been a few years back, but I still don't use it.
The bad thing is, is that fleas can develope an immunity towards flea products over time. Advantage may work for some dogs where as Frontline may work better for others. If you look at the back of a Frontline box, it says it is safe to apply once a week, safe to use on nursing bitches, and is water proof...
I have never given my girls flea products or heartworm while PG and nursing.
