My 12 year old Schnoodle, Liberty, had great success with the Woundwear A-Trac Dynamic Brace after tearing her ACL. We ended up saving so much money and Liberty isn't dealing with the aftermath of an unnecessary operation. Our vet assured us she would have problems if we didn't operate. But with a few months of your brace, she is doing great. No limping even after a 2 mile run. It's so great to see my little girl live life again! I would highly suggest the Woundwear A-Trac Dynamic Brace to everyone!
