"Our German Shepherds are much more active and act much younger with a daily dose of this. I have teased about trying it myself. "

"Our German Shepard has bad hips and once we started giving this to her, she acts like her younger self again. The other two dogs are not so happy. She likes to kick their butt, even though she is the smallest."

"My small -30lb- 12yr old dog has had 3 acl tears and had 3 surgeries. She was very limited in her movements. This k-9 Actiflex has made a huge difference. Within 2 weeks she was a different dog."
