Poor Terry sounds very sick. I see that he's a young puppy as well, and I'd be concerned that he doesn't have all his vaccines yet. He could be suffering from parvovirus causing his symptoms. Other causes include a severe GI illness, eating something rotten or toxic, or a foreign body. He sounds sick enough to need veterinary attention now. Please take him into one immediately.
