OUR DOG HAS NEW LIFE. This company blows me away. So diligent. So caring. Such passion to help our beloved animals. And RESPONSIVE. And more than fair/generous. We started with the Endurance brace and struggled with the fit at first. When we were getting close we broke it while molding/adjusting it. (Glenn "held our hand" along the way with advice.) We received the Performance brace AT NO CHARGE and tried it out. It's simple as pie to put on. Our chocolate lab, Rocky (11 years old), has regained strength, endurance and, most of all, he has his "happy" back. OK, he's a lab. He has his "happier" back. We're so grateful to Glenn and Animal Ortho Care for helping us so patiently -- not to mention their fine products. We're definite disciples!
