A dog's ACL (cranial cruciate ligament) tear typically presents as a sudden, severe limp, significant knee swelling, and inability to bear weight on the hind leg, often with a "sitting sideways" posture. Conversely, a sprain usually involves milder, temporary discomfort, allows for some weight-bearing, and improves with rest.
