Glad he's ok also Tink. Had the same thing happen to our shepard, as she was older and could not see well and fell in twice. Once DH left her out and I didn't know, he forgot, we went grocery shopping and on returning heard her barking, she was half in half out, but couldn't get all the way out, her fur on top was all frosty and frozen, I was so glad she warmed up fast, and didn't have problems because of it.
