Their rear legs are fairly rigid and sturdy. The front legs are loose and flexible, with only muscle attaching them to the torso. The dog's muzzle size will vary with the breed. Dogs with medium muzzles, such as the German Shepherd Dog, are called mesocephalic and dogs with a pushed in muzzle, such as the Pug, are called brachycephalic.
The double suspension gallop is a leaping gait, with the hind legs first propelling the dog into the air and then followed by the front legs propelling. The shoulder muscles, the ham muscles and the back muscles are the engines of this motion. [2] Although speed is gained by animals using this gait, endurance will be sacrificed.
This dog's stifle joint is labeled 12. The stifle joint (often simply stifle) is a complex joint in the hind limbs of quadruped mammals such as the sheep, horse or dog. It is the equivalent of the human knee and is often the largest synovial joint in the animal's body. The stifle joint joins three bones: the femur, patella, and tibia.
One rear leg will flex while standing. Over the next few months, it will begin to affect the other rear leg. Eventually, the dog is alternatively flexing and extending each rear leg in a dancing motion. Dancing Doberman disease progresses over a few years to rear leg weakness and muscle atrophy. No treatment is known, but most dogs retain the ...
Stifle injuries are one of the most common causes of lameness in rear limbs in dogs, and cruciate ligament injuries are the most common lesion in the stifle joint. A rupture of the cruciate ligament usually involves a rear leg to suddenly become so sore that the dog can barely bear weight on it. [7] How a rupture can occur:
A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).

Fetlock is the common name in horses, large animals, and sometimes dogs for the metacarpophalangeal and metatarsophalangeal joints (MCPJ and MTPJ). Although it somewhat resembles the human ankle in appearance, the joint is homologous to the ball of the foot. In anatomical terms, the hoof corresponds to the toe, rather than the whole human foot.
