He is adorable!! You must be having so much fun!!

I also used Frontline on Dale and we used Interceptor for the heart worm pills, b/c it also kills whipworm. If he has a yard of his own then Heartguard would probably be fine, but if he is going to be at a lot of dog parks, and places where there are other dog's fecal matter ( sorry) , then i would use interceptor, b/c he could get whipworm from stepping in poop, or (eating) it, soory again Dale had whipworm before we put him on Interceptor (Heartguard doesnt't have a preventative in it for whipworm) and it was no fun for me or for poor Dale...

BTW~ Interceptor is more of a hard vitamin (Dale wouldn't chew it, so I had to show it down his throat every month, but Heartguard is chewy, so he ate that right up)...anyway, i am sure your vet will lean you towards which one you should use...

Anyway, lots of luck with him, he is a doll!!
