This our 13 year old Dusty, she has never had good hips and we have done everything we can do to help her deal with the discomfort. We have been using Rimadyl and other supplements. Recently we decided to try Canna-Pet and saw that she appeared to be in less pain. After a couple of weeks we have reduced her Rimadyl to just one a day and it seems she has no ill effects from the change. Our goal is to eliminate the meds. Very happy to have given this approach a try.
