Yes, a dog can physically bend its knee with a torn ACL (cranial cruciate ligament, or CCL in dogs), but they often avoid doing so due to severe pain, instability, and inflammation. Instead of normal bending, dogs with a torn ligament often show stiff-legged movements, limp, hold the leg up, or sit with the leg out to the side.

How can you tell if a dog tore their ACL?

Symptoms of a torn ACL (or CCL, cranial cruciate ligament) in dogs include sudden or gradual limping, refusing to bear weight on a hind leg, holding the leg up, "toe-touching," stiffness, swelling around the knee, difficulty jumping or rising, and sitting with the leg extended sideways. An audible "pop" or "click" during activity can also signal a tear, with severe cases involving constant lameness.
