Does a dog's torn ACL heal on its own, or is surgery needed?
Hello, and thank you for using Petco Pet Education Center, formerly Petcoach. I'm sorry to hear about Jaeger's injury! Unfortunately, a torn ACL will not heal, as ligament tissue cannot re-grow. So, he does need surgery in order to maximize his ability to use that leg. With that said, there are certainly plenty of dogs (and humans!) out there who do not have their torn ACL surgically repaired, and instead manage the injury with pain meds, anti-inflammatories, and rest as needed for life. But, without surgery that stifle ("knee") will remain unstable. Additionally, dogs who tear one ACL are at increased risk of tearing the other, which in my opinion adds another reason to pursue surgery, so if that happens Jaeger wouldn't have *2* unstable stifles. I hope this helps - you're welcome to request a consultation if you'd like to discuss Jaeger's injury in more detail!
