She loves them

I got these for my dog who had knee surgery because the ones at the vet were expensive. She loves these and she seems to be walking and playing around more.

I was considering buying these treats for my two dogs that have Hip Dysplasia, but too many bad or so-so reviews. For those who did not like the treats, thought they were too expensive, or their dogs did not like them. You may want to try Dasaquin supplemental treats. They were recommended to me by my Vet.

My nearly 14 year old shepard mix seems to have a little more energy and ease of movement since I started him on these. If it were't for his partial blindness and deafness, he's like a new dog.
