My little man will be 15 in December. He had a birth defect on his left foot / leg and has had a minor surgery. His defect compounded with old age arthritis had him feeling down. I was noticing him limping and requiring pain meds more often. I’ve had him on one (1) canna-pet small dog for several months now. His mobility is improved and requires very little pain meds. Woohoo! Thank you for a great product.
