Corey just finished eating a treat I set up for him. Soup (beef stew type thing) that I had left over from lunch and dog food. He came in and sat next to my feet where I noticed him shivering uncontrollably and panting. When I called him up onto the couch he moved slowly as if he didn't want to jump up. He just jumped down and headed over to his crate. I'm a little worried about him.
