My best friend, 13y.o. super arthritic lab, Sunny has now been using C.H.O. Pet tincture for 6 weeks. When I first started using it, I saw a huge transformation in my dogs anxiety level. Her excessive barking and forearm licking decreased by 75%!!! And then little things start happening, she began to play again and do her wild dog run (very short busts as she is pretty old). She also was more willing to get up and start begging for food again. Her sleep also appears more restful. I feel in her senior years, C.H.O. has provided her with the comfortable quality that she deserves. She is now a really happy old girl and it makes my heart happy!!!
