I started my 12 year old pit bull Jewels on Canna Pet Advanced Max Liquid because she has very bad arthritis in her hips and knees. The results were remarkable. She has been so much more agile and is able to enjoy her walks again. It only takes 6 drops a day, and she has responded beautifully with no side-effects. I feel that the quality of her life has been vastly improved. She can enjoy the things that she loves like walking and even doing a slow jog. She can handle the colder weather with much less discomfort. Thank you for this amazing gift.
