My baby had the fast heartbeat too.
It settled down after an hour or so and the vet didn't it was "connected" to the shot.
That's her first and last dose of that stuff.

Our mastiff puppy had it, didn't have any reaction whatever. I guess we'll have to do the monthly thing, though...

Yeah, I agree, we are gonna stick with monthly pills too. Our vet did admit that the fast heartbeat and other symptoms were directly connected to the shot. As far as your baby, hope there won't be any lasting ill effects from it.
