My dog did not go out of the yard and is now limping lame on one of his hind legs
Anterior cruciate ligament rupture in dogs
Often time vets are confronted with this situation in veterinary clinics. As far as the owner knows their dog would not have been subject to any trauma, yet they can hardly take weight on one of their back legs. There are many possible causes but by far one of the most common reasons for this situation occurring is a tear of the major small ligament inside the knee.
