We have a 14 year old Yorkie named Oliver. He was an avid runner believe it or not for a good 10 years of his life. He tore his left hind leg ACL 2 years ago. He sustained a similar injury just 2 months ago on the right side. He takes one capsule in his last meal of the day. It noticeably reduced his anxiety and he sleeps better when taking his Canna pet. Recommended by our veterinarian, we feel blessed to have this product available for Oliver…Thanks Canna-Pet !!!
