Joint supplements for 12-year-old Boxer

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 12-year-old Boxer coming out of a vet check-up is a very specific case, and getting the right supplement matters more than just picking something off the shelf. What's his or her weight roughly, and what are you noticing day-to-day — morning stiffness, slowing down on walks, hesitating on stairs?

That's a really clear steer from your vet, and 28kg with moderate arthritis at 12 is exactly the profile where supplement quality makes a noticeable difference. Boxers are prone to joint issues anyway, and at this age the cartilage is thinning rather than just inflamed, so you need something that addresses both. Can I ask — has she been on any supplements before, or is this the first time?

Your vet gave you a good shortlist — glucosamine and green-lipped mussel together is exactly the right combination for moderate arthritis in a senior dog. Green-lipped mussel adds omega-3 fatty acids that reduce joint inflammation, which glucosamine alone doesn't cover. For a 28kg Boxer at this stage, I'd go with YuMOVE Senior for large dogs. It's formulated specifically for older dogs with existing joint stiffness — it has a higher active ingredient concentration than the standard YuMOVE range, includes green-lipped mussel, glucosamine, and hyaluronic acid, and the dosing is calibrated for dogs over 25kg. It's one of the few supplements with genuine clinical trial data behind it, and it's widely stocked on Amazon UK. You'd give her two tablets a day for the first six weeks, then drop to one as a maintenance dose. Most owners see a difference in morning stiffness within four to six weeks.

It's very well tolerated — Boxers rarely have issues with it. The one thing worth watching: if she's on any blood-thinning medication, mention the green-lipped mussel content to your vet, as it has mild anticoagulant properties. Otherwise, the main thing is consistency — it works cumulatively, so skipping doses in the first few weeks slows the results. On the weight side, if you want to tighten up her diet to support the joints, that's a separate conversation worth having, but the supplement is a solid first step on its own.

Perfect choice. Give it six weeks before you judge it — the first signs are usually easier mornings and a bit more willingness to move around after rest. If you want to revisit the diet side once she's settled on the supplement, come back and we can work through that too. Hope she's moving more comfortably soon.
