Arthritis in Two Senior Dogs, Different Weights

Two senior dogs in the same house, both arthritic — that's a real management challenge, especially when their weights are different. Most arthritis supplements are either underdosed for larger breeds or overloaded with inactive fillers, and when you're buying for two dogs at once you really need something where the dosing can scale properly to each animal. Before I point you in a specific direction, can you tell me roughly how much each of them weighs, and what you're seeing day to day — morning stiffness, trouble getting up, hesitating on stairs, shorter walks?

That's a really useful picture — they're presenting differently even though the underlying issue is the same. Your Lab's reluctance to rise and shortened walks suggests more advanced joint degradation, which is common in larger, heavier Labradors at 13. The Golden's stair hesitation but relative ease once moving points to stiffness that's still in a more manageable phase. The weight difference also matters: 36kg versus 28kg means the Lab needs a meaningfully higher therapeutic dose to get the same effect. Can I ask — are either of them on any medication from the vet, like meloxicam or carprofen? That affects what I'd suggest.

The cheap supplement not working is almost always a dosing or formulation issue — most budget options use low-grade glucosamine that absorbs poorly and sits well under the threshold that actually does anything clinically useful. For two dogs of this age and size, I'd go with YuMOVE Advanced 360 for Large Dogs. It's a meaningful step up from standard joint supplements — it combines a high-absorption green-lipped mussel extract with collagen, hyaluronic acid, and antioxidants, and it's one of the few products with genuine efficacy data behind it rather than just marketing. Because it's dosed by weight, your Lab at 36kg gets a proper therapeutic amount rather than a token dose, and you can give the Golden a slightly reduced amount that still hits the effective range for her. For the Lab specifically, the collagen and hyaluronic acid component is really important — at his weight and level of stiffness, cartilage support matters more than it would for a smaller or less affected dog. You should expect to give it consistently for six to eight weeks before judging whether it's working — joint supplements need time to build up.

One product and splitting by weight is completely fine here — that's exactly how it's designed to work. Buy the large dog version and dose your Lab at the full recommended amount for 36kg, and your Golden at the amount for 28kg. You'll get through it faster than if you had one dog, so it's worth checking the tablet count before you buy and considering the larger pack size — it works out noticeably cheaper per dose and you won't want to interrupt a consistent routine once they're on it. One thing worth flagging: given your Lab's level of stiffness and the fact he responded to meloxicam, it's worth mentioning the supplement to your vet at his next check and asking whether a low-dose ongoing NSAID alongside it might be appropriate. Supplements and medication work on different pathways — they're not mutually exclusive.

Good — look for the large breed version specifically, and if you see a subscription option it usually saves around 20% which adds up when you're dosing two dogs. Give it the full eight weeks before you make a judgement call, and if you want to track progress it genuinely helps to note down what you're seeing now — how long it takes the Lab to get up, how many stairs the Golden takes comfortably — so you have something concrete to compare against rather than relying on memory. I hope you see a real difference with both of them.
