Opie has issues with arthritis. He would take a long time to get up (I would usually have to help him) and when he was up it would be at least 2 or 3 minutes before he put any weight on his leg. After being on Canna-Pet for about a week or two he was able to get up on his own without help and actually walk around a lot better. He was able to put weight on his leg and was as good as a 15 year old mini schnauzer could be! I am more than satisfied with the results. Thank you Canna-Pet!
