ArthroFlex Perna K-9 is a powdered dog joint supplement built around green-lipped mussel (Perna canaliculus), a natural source of glycosaminoglycans and omega-3s. It is sold as a 16 oz tub that mixes into food, aimed at older or stiff dogs and larger breeds that need ongoing joint support. Compared with chewable glucosamine tablets, it is a food topper rather than a treat, which suits picky dogs but demands a dog that eats wet or mixed food. Owners generally report easier movement in senior dogs, while the main complaints are the mussel smell and the need to measure each serving.

Owners of senior and large dogs most often describe better mobility after several weeks of daily use, especially on stairs and rising. The recurring complaints are the mussel odor and the fuss of measuring powder into every meal.
