Query: Great product and a great price!

My vet recommended this product for my 9 yr old golden retriever. She has bone cancer and is 3 weeks post amputation. Due to more stress now on 3 legs, I have been giving this to her everyday since. Vet charged $50 for this same product, yikes! My dog will not take it as a treat, so I have to break it up and put it in her food. She has no problems eating it now :) She seems to be less stiff and much more mobile.
