Could be parvo...
I'm not a vet. And this is probably not the place to ask advice. This is the place to ask questions about the business (it is not a vets office) In my non-professional opinion it sounds as if your dog has ingested something that is making him sick. You need to call an emergency vet/animal hospital
Take him to the Vet ASAP he could have gotten poisoned!!!
