My initial go to is always a trial period of crate rest. If things get worse, then it's vet time. If things stay the same after a few days, I monitor for a few more. If it still doesn't start to improve, vet time. I have yet to have to take a dog to a vet for a joint injury using this protocol.
If you need equipment to maintain control of your dog, understand you’re hanging on to your dog’s body because you’ve lost his mind!
