What physical conformation detail allows the Whippet's stifle for long reach in stride?
Answer
The stifle (knee joint) should be well bent
For the Whippet to achieve the long, free, and elastic stride characteristic of its efficient gait, the structure of the hindquarters is paramount. Specifically, the stifle joint, which corresponds to the knee joint in humans, must exhibit a significant bend. This well-bent stifle allows the powerful rear assembly to achieve a maximum reach when driving forward. When the dog is in motion, this structure ensures that the hind legs track parallel to the forelegs, promoting straight tracking and minimizing lateral deviation. A straight stifle would severely limit the extension needed for covering ground rapidly.
