Salmon oil alone isn't enough for dog joint health — what to add

Your vet is right — omega-3 from salmon oil is a useful anti-inflammatory foundation, but it doesn't provide the glucosamine, chondroitin, or joint lubrication components that directly address cartilage structure and synovial fluid quality. It's part of the picture, not the whole picture. How prominent is the stiffness, and how long has he been on just the salmon oil?

A year on omega-3 only — the anti-inflammatory foundation is there, which is actually useful. Rather than switching everything, I'd add YuMOVE Senior to what you're already doing. The green-lipped mussel in YuMOVE Senior overlaps partly with salmon oil on the omega-3 front, but it adds the glucosamine and hyaluronic acid that the salmon oil doesn't provide. The two together give you anti-inflammatory action plus structural cartilage support plus synovial fluid quality — the full stack. You can continue the salmon oil or reduce it, but YuMOVE Senior at the correct dose for his weight is the main event.
