I bought this for my 12 year old arthritic rotti. She absolutely loves them and is convinced I'm not giving her enough. I am however anaphylaxic to shellfish and I realized quickly not to handle them (my fingers went instantly numb and I had to wash them off quickly before more reaction happened), but I just sorta shake them onto the floor for her and she would fight a cat for them (that's saying alot !). I will absolutely buy more. It helps her move so much better its not insane expensive like some of the other products I've tried, and although I'm severely allergic to the main ingredient, the way the container is, I can simply just shake out the amount she needs and she gobbles them up. Very happy with it. Completely recommend.
