Cranial cruciate ligament tears are very common in dogs. Learn how these injuries happen, and what you can do to try to prevent them.
A cranial cruciate ligament injury in a young, healthy dog is typically an athletic injury. In older dogs, it is usually an injury of chronic wear and tear. This explains why its so common for a dog who has damaged the CrCL on one side to then tear it on the other side. When you take one back leg out of commission, the work load shifts to the other, increasing the strain on the ligaments of the good leg.
