Just bought these today after a nice lady at Petland in Cold Lake, Alberta recommended Mojo Pet Supplements to us. We have an 8 year old Maremma (large dog) and she’s experiencing some bad arthritis, to the point where she was dragging her feet and kind of two stepping like a toddler learning how to walk down stairs. After only a half hour after giving her a Mojo Pet Supplements, I noticed a difference in the way she walked. She was lifting her feet up properly again! we’ll see how these chewable tablets work in the long run:)
