To tell if a dog has a torn cruciate ligament (CCL), look for limping (mild to severe), holding the leg out to the side when sitting, stiffness getting up, trouble jumping/stairs, swelling around the knee, or a "toe-touching" stance, with complete tears often causing sudden, non-weight-bearing lameness after an awkward movement. A vet diagnoses this with a physical exam (drawer test) and sometimes X-rays, looking for instability and pain in the knee joint, notes woodgreen.org.uk and vetmedbiosci.colostate.edu.
