1. I WAS using Interceptor for heartworm before they discontinued it. Now I use Sentinel for heartworm which I believe includes med for fleas. If it's just a flea prevention you're looking for an not include tick, maybe Sentinel is something you can consider.
2. Is your puppy eating really fast? I think I read that might cause the tummy to bloat.
3. I think this is a matter of training of which I'm sure a lot of members can recommend.
