He threw up repeatedly and he hasn't this morning but he acting weird. He won't move much he had his parvo shot he is only 3 months he is an blue fawn pit bull mixed with an German rottweiler

There are other things out there besides parvo that can kill your puppy..

Puppies go down hill quickly... To be safe, you should really take him into the vet.

And for puppies to have any type of immunity, a series if 3 shots need to be given. Your puppy with just one parvo shot is still at risk.
