Thanks so much everyone. I got him from the humane society. They said I could come back and get another dog. I might. I'm not sure right now though. I took him (Rusty) back to the emergency vet.. the one that's open 24 hours a day. The vet put him down at 7:00 this morning. I couldn't stay for it... I really just couldn't do it. So I came home. He's not hurting anymore though. And I am thankful for that. Thanks again everyone.
