When attempting to put crestie back in his cage my dog got ahold of him. I picked him up and while holding him he was shaking and his mouth was opened really wide. His tail also looks as if it was seizing. He's been trying to move around and he'll drink some water, but not eating. He can't move his back legs, I'm not sure if it's his spine or just the legs. I don't live near any exotic vets. I'm not sure what to do. Please help!
