Supplements for 3 dogs at different life stages

Three dogs at completely different life stages is a genuinely tricky supplement situation — and honestly, the supplement market is enormous and mostly unnecessary. Most healthy dogs on a complete commercial diet don't need anything added, and when they do, it's usually something targeted rather than a broad daily multivitamin. That said, a 12-year-old is a different story to a 1-year-old. To give you useful advice: what's prompting the interest in supplements right now? Is it the senior dog showing signs of stiffness or slowing down, general preventative thinking, or something else entirely?

That's really helpful. Morning stiffness and slowing down in a 12-year-old mixed breed is classic age-related joint change — it doesn't necessarily mean arthritis, but the joints are almost certainly feeling the years. A joint support supplement with glucosamine, chondroitin, and green-lipped mussel is where the decent evidence sits for older dogs. The honest answer on the 'one product for all three' goal though: what your 12-year-old needs, your 1-year-old genuinely doesn't. Giving a young dog a joint supplement isn't harmful, but it's also just money out the window. Is the simplicity goal about cost, routine, or both?

Understood — and that's a fair trade-off to make consciously. Here's what I'd actually do in your position: get one product that's genuinely useful for the 12-year-old and won't harm the other two, give it to all three for simplicity, and accept that only the senior is really benefiting from it. The product I'd point you to is YuMOVE Joint Care for Dogs — the standard adult formula. It has real evidence behind it, it's well-dosed on glucosamine and green-lipped mussel, and it's one of the few supplements that actually has clinical trial data in dogs rather than just borrowed human research. It comes in chewable tablets, which most dogs take readily. The 1-year-old and 5-year-old won't be harmed by it and frankly at 5, a bit of early joint support does no harm either. Your 12-year-old is who this is really for. You might see a difference in her morning stiffness within 4 to 6 weeks — if you don't, it's worth a vet conversation about whether something more is going on.

Yes, they have a few: the standard adult, a Senior formula (YuMOVE Senior), and a more concentrated PLUS version. For your household, I'd go with YuMOVE Senior for Dogs — it has a higher active ingredient dose than the standard adult formula, which is appropriate given your eldest is 12 and actively showing symptoms. It's safe to give to the younger two at the senior dosage. The PLUS version exists for dogs with more advanced joint problems and is noticeably more expensive — you don't need to start there. Pick up the Senior, give it consistently for six weeks, and reassess. It's widely available on Amazon UK in tub sizes that make sense for three dogs.

Good luck with it. Keep an eye on your 12-year-old specifically — if the stiffness is severe or she seems uncomfortable rather than just slower, it's worth getting a vet to check her joints properly before you rely on supplements alone. But for what you're describing, this is a reasonable first step and a genuinely useful product.
