I give these to my two dogs for joint stiffness and early arthritis. They both like them and there's no side effects.

The biggest factor in my glucosamine search has been trying to find the most palatable option for my picky dog. I love him to death, but he's a stubborn sh-t. And he will actually eat these! They don't smell too horrible or leave my hands feeling gross either. For my dog's size, he's supposed to start with 3/day, but my biggest complaint of these is they're very expensive. At 3/day that would be almost $50/month. I've been doing just one so far and am expecting results similar to any other glucosamine/chondroitin product. If you're looking for a palatable option for a picky eater, then I definitely recommend these!
