Thanks for all the support everyone. Even though the dog is not mine I spent a lot of time with him over a long period of time.

Unfortunately the old boy had more serious problems than I envisioned, and he had to be put to sleep. Beyond just being out in the cold, he had a cracked rib and lung issues. The vet thought perhaps he had been bitten (crushed) by a big dog. I think he was either kicked or hit by a car.
