Reviews
"Perfect for seniors"
Posted byMarion16th Sep 2026Both my senior dogs have enjoyed the benefits of Tandem Bone+Joint for quite awhile ago for their arthritis and general wear and tear of their old bodies, and I can say, it is the best way to give your dog (or cat) extra support for their joints and bones. Mixed with some wet food for fussy eaters, its easy to measure correctly without going through several different supplements separately. And it does not smell strongly like green mussel powder sometimes does!
"Both cat and dog love this. "
Posted byKellyon4th Sep 2026We've not long been using this but both pets love the taste. Looking forward to seeing some change in my cat's arthritis symptoms soon. I wish he could tell me if it's helping.
"My cat loves this "
Posted bySarahon10th Aug 2026My fussy senior cat loves this. I add it to a little bit of water to hydrate her biscuits or to her wet meat (so she doesn’t get food boredom).
"Dog’s mobility "
