My vet called me yesterday to say she got a call from the radiologist...he said he didn't see anything in the lungs...the heart was a little rounded, nothing real bad I guess. Some tracheal collapse. The thing is, the vet said lets watch him a little bit. Well, this morning I notice when he sleeps for any length of time and gets up, he gets up with his back hunched up and walks real slow, head bowed some. His neck has a twitch. Has anyone seen a dog with their back hunched. He also doesn't shake as hard as he used to to get the rain out of his coat...he is real careful. I can't help to think he is in pain from his spine? I don't know. Any ideas would be great. I left a message for the vet for this Monday.
