Its not always a parasite, my pups get unset when they eat other animals poo or get into the trash and eat foods they shouldn't. And yes, sometimes medications too, so it could be possible that your pup is having a reaction to the Heart guard med but be sure to ask your vet abut it and do not discontinue it unless you have a back up.
I have hear of some people giving the tablet in two parts. One one day the other the following day. Maybe this will help your pup if this is the issue but it is important that she get the entire chew.
