Poor Boi! Arthritis can feel worse in cold weather, which is likely why he won't leave the dog house. If possible, I'd bring him inside. He'd be warmer and more comfortable in the house. I'd take him into the vet to check out that sore on his butt, the fact he's getting weaker, and he can't put on weight. Those last two things make me think he is sick, and that should be checked out by a vet promptly. Best of luck.
