If y'all have an older dog, that's starting to move a little slower, I found some things that might help. My wife found some OTC glucosamine/chondroitin chews, Pet Armor Joint Health Supplement, years ago. They worked so well, and dogs don't get a placebo effect, I started taking a glucosamine/chondroitin supplement; for humanoids. Our current old dog, Black Lab/Blue Heeler mix, developed a limp, even with the OTC supplements. The vet prescribed Meloxicam, an anti-inflammatory. It works well, and is very inexpensive.
The OTC supplements allowed our 14 year old mutt to go from walking around like a 14 year old dog. . . . to actually running and jumping in to the back of my truck. He lived another four years comfortably. It's a maintenance med, and takes a couple of weeks to kick in, but well worth it.
