The cruciate ligament of dogs is similar to that of humans. It is called CCL (Cranial Cruciate Ligament) in English, or ACL (Anterior Cruciate Ligament). When the cruciate ligament is injured or torn, there is no connection between the two leg bones, and the lower leg bone is displaced forward.
Unlike humans, which are usually torn due to external force or injury, cruciate ligament damage in dogs is almost a consequence of long-term use, so dogs that are more active in daily life and love to run and jump are more likely to be injured before middle age. According to Vet, after the injury, the tear is only a situation sooner or later.
Are cruciate ligament injuries common?
Very common and can be injured in dogs of any size, especially dogs that are more active on a daily basis, as well as St. Bernard, Ronaway, Labrador, Akita, American Staffordshire Terrier, Mastiff, Medium-to-large dogs such as the Newfoundland have a genetic predisposition to tear the cruciate ligament more easily than other dogs.
The initial injury may be only a partial tear, and the symptom is lame leg, especially when lying down and standing up. It is normal after a little stretch or activity, so it is easily ignored by parents. After a complete tear, the hind legs can't touch the ground, especially the calf, the dog can hardly control it, it's just implicated by muscle tissue.
Can a cruciate ligament injury heal on its own?
cannot. Ligaments, unlike muscles, skin, and bones, cannot repair themselves because they have no blood vessels.
