Miner has a hitch in his giddy-up

While out on our walk/run this morning, Miner started limping a little. So I turned us around at the bike path and headed back. It got progressively worse and he was putting as little weight as possible on his right foot. I wound up taking him to the vet. She thinks it's probably a sprained shoulder. He can't move his right leg the same as his left. Doggie Advil and rest for two weeks. If it doesn't improve by Monday or Tuesday, I'll take him back in for X-rays. :( Poor boy. He has to be shut in the guest room when I leave, so he's not hoping up at the back window or doing much wandering around.
