Started using for a hunting dog that had strained his hip and had an ACL repair. He has a Benefab matt on his Orthobed, but within a few days of wearing this was noticeably better. He didn't walk with a hitch in his gate and was using his body as he should instead of favoring the one leg. Highly recommend for all dogs. We will use this the night before hunts to help warm his joints for those long days in the marsh.
