“Our 10 year old Keena loved going for hikes and climbing up on rocks until about a year ago and she just lost her “pep.” I saw the ad for K9 Rx and was excited for her to try it. It took about 2 weeks for us to see the difference in her step. She is more agile and is able to hike for five miles or more with us and Keena loves the flavor it gives her food. Thanks for giving us our hiking partner back.
