Dog arthritis supplements for Weimaraners

Most arthritis products for dogs are either underdosed or poorly matched to the dog's specific situation — size, age, and severity all change what works. A giant breed like a Weimaraner at ten years old with confirmed early-stage arthritis needs something genuinely therapeutic, not a token joint chew. What are you noticing day to day — morning stiffness when he gets up, reluctance going up stairs, or is he just slower to get going on walks than he used to be?

That morning stiffness that eases once he's moving is really classic early-stage arthritis — the joint fluid warms up and things loosen off, but the underlying inflammation is still there. At 32kg he needs a proper therapeutic dose, not something designed around a 10kg spaniel. The vet endorsing supplement support is a good sign too — it means the joint damage is real but there's genuine room to slow progression. Can I ask — has he been on any joint supplement before, or is this the first time you're looking at this?

Good — starting fresh means you'll have a clear baseline to measure against. For a confirmed-diagnosis, large-breed dog like yours, I'd go straight to YuMOVE Advanced 360 for Large Dogs. It's the step up from standard YuMOVE, and that matters here. It contains a higher concentration of ActivEase Green Lipped Mussel — the omega-3 source that has the most evidence behind it for canine joint inflammation — plus glucosamine, chondroitin, and hyaluronic acid at doses that are actually sized for a dog his weight. YuMOVE is the UK's number one vet-recommended joint supplement, and the Advanced formulation is specifically designed for dogs that already have a confirmed diagnosis rather than those just starting to show early signs. You'd give him two tablets daily with food. Most owners report visible change in mobility within four to six weeks, though some see it sooner. It's available on Amazon UK, typically around £30–35 for a 60-tablet pack. Given his age and the confirmed X-ray findings, this is the one I'd start with.

Definitely tell the vet — not because there's any conflict, but because it's useful information for his records and they may want to factor it into future check-ins. In terms of what to watch for: green lipped mussel is very well tolerated, but occasionally dogs get mild loose stools in the first week as their gut adjusts. If that happens, just give it with a bigger meal for a few days and it usually settles. Keep a simple mental note of where he is now — how long the morning stiffness lasts, how far he walks comfortably — so you have something real to compare against at the six-week mark. If you're not seeing any improvement by eight weeks, that's worth raising with the vet to discuss whether a prescription anti-inflammatory is needed alongside.

Great choice. He's in a good position — early diagnosis, vet on board, and a supplement with real evidence behind it. Give it the full six weeks before judging it, and keep those morning warm-up walks gentle so he can move without overdoing it. I hope you see him bouncing out of his bed before long.
