Emi with cruciate injury

Just found this photo from 1999 just after we adopted Emi. She collided with two labs playing ball. We found out she had really weak cruciate ligaments. The vet at the time thought she may have to be operated on, however with some tlc and giving her glucosamine for a while she is fine. Her back legs have always been weaker than the front and she bunny hops sometimes but she can still run like the wind for her ball even though she is 13.
