We’ve all seen it. The eye a Border Collie gives sheep when he or she is working them. The breed is famous for that “eye,” but there is one other thing (two, actually, when you count their wicked smarts) for which the Border is known, and that is the low-crouch-to-the-ground position.
This “stalking” motion really gets the attention of sheep because it mimics predatory movement, but not every herding breed can do this for a simple reason: If a Border Collie is built correctly, there is more space between the tops of his shoulder blades than in other breeds.
Let’s review. A dog’s scapula, or shoulder blade, doesn’t articulate with any bones at its top, but is attached by four muscles to the spinal column at a number of places. At the most forward and lowest part of the scapula is a shallow socket, and this area is called the “point of the shoulder.” The highest point of the shoulder blade is the withers, and the space between them in a correctly built dog is usually about the width of a human finger. In a Border Collie, however, that space is more like two finger widths, and it is this that allows a Border Collie to crouch and lower his head while he moves.
It is a marvel to behold in action. See for yourself:
