A torn ACL (cranial cruciate ligament or CCL) in dogs typically presents as sudden rear-leg lameness, "toe-touching" while standing, knee swelling, and reluctance to rise or play. Watch for a "lazy sit" (leg extended to the side) and hear for a clicking sound from the knee.

Can a dog heal from a torn ACL without surgery?

Yes, a dog's torn ACL can heal without surgery, especially for small dogs or partial tears, through conservative management like strict rest, activity modification, physical therapy, bracing, anti-inflammatory meds, and weight control; however, surgery often provides better long-term stability and function, particularly for larger, active dogs, as non-surgical recovery might lead to chronic issues like arthritis. A vet must diagnose the tear and determine the best approach based on your dog's size, age, and activity level.
