Thank you, HB. Turns out he "blew" out his knee, just like an athlete only he lays around the house smile) He has to have surgery on 7/1. Crate time until then. I was so worried it was something the Vet wouldn't be able to fix, and he'd suggest putting him to sleep. He is 9-1/2 years old, so I was expecting something like that to start. Fortunately, it can be fixed although expensive, but he is my baby and I'm grateful there is a solution to his injury.
