"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."

"I love k9 actiflex it has done great things for two of my dogs. One has had knee surgery on both knees and moves much better while on this product. I had tried glycoflex with her before and was not impressed but this product has been great. My other dog is three legged so she tends to have some pain and stiffness in her back, this product has also done great things for her. She is much more comfortable while on this product."
