I was getting the beef joint chews, however they have become more difficult to get now and are always out of stock. Not an issue for my dog as it was choice, and not due to an allergy of any kind. I have just started my old chihuahua with luxating patella in both back legs on the chicken ones, she is taking them with her food no problem. She has been taking the beef joint chews for a few months with drastic noticeable improvement. She has been running around like a puppy in the house, and walking further on her walks instead of not wanting to walk at all. She also has focal seizures, these have not affected her seizures in any way, which is fantastic as they seem to be helping her mobility a lot. I highly recommend trying your dog with these, if they may help. I am aware they may not work for every dog, but so far they have been a miracle for my girl, and I hope they continue to help her to live her best life.
