My 12-year-old lab, Princess, has responded very well to your product. She was once a lab that acted her age with aching hips and slowly walked to and from outside. Now, she is spunky and wants to play. She even decided recently, after taking the supplement for about 6 weeks that she wants to run when we go for a walk. What a pleasant surprise. She also loves the taste as she gets even more excited than a lab usually does (if that’s possible) when it is time for a meal. Great product!
