My dogs love these, they get excited whenever I ask them if they want a vitamin. My dogs are small dogs, so don't think only big dogs enjoy these. I can't say how effective they are, my dogs don't have any joint problems yet, I'm just being proactive by giving these treats. But the ingredients are supposed to be good for joint problems, even in humans

These pill treats are junk. The dough is dry and hard; they tear and crack when inserting pills. They are difficult seal. About a third of the pills in the several pkgs I bought were squished and flattened to the point of unusability. The manufacturer would not answer my email and Sam's Club customer service just recommended returning them but I needed a receipt.

I give my labs 4 of these a piece every morning!!!

Very good. My dogs like them.

Every time I give my dog one of these, she gets sick and throws up.

My dogs will actually eat these!

So hard my dog just spits them out! Wouldn't recommend.

My Lab loves these treats & she walks & gets up much easier after only a few months!!

Summer 2019 my pet was so allergic to this he was so allergic and miserable ??? I finally took him off and it all cleared up. Buyer beaware

My dog absolutely loves this!! She loves the taste, and I love giving them to her as treats knowing they are helping her!
