"My dog was diagnosed with torn ligaments in his knee. The vet wanted to operate on him. I read about this product and tried it instead. Within 2 weeks, and with limited activity, I noticed vast improvement on his leg. Now 5 weeks later and he is totally back to normal!"

"Wonderful product! Made all the difference in my dog. When she quit going on trail rides with me I realized that I had to do something. After just 2 weeks she was a completely different dog...and we are back to our 2 mile trails! Thanks Cox Vet Labs!"

"My 13 year old lab has had arthritis for some time and limped frequently. I was already impressed with the results from using the equine Acti Flex for my horse so I decided to try the canine product. I experienced the same results with my dog. She has a pep in her step, can run to the house from the barn for dinner and her limping is minimal."

"My 120 pound Boerboel injured her patella and I doubled up on this for a couple of months and her luxated patella completely healed and she hasnt had any symptoms of the injury. Its amazing stuff! She couldnt run or cut without the knee popping out of joint which left her leg dangling. Now you would never know she ever injured it."
