The Scapula (shoulder blade ) muscle configuration is somewhat complicated and all we have to remember that correct angulation and layback of shoulder ensures the muscles are of the correct structure, e.g. short upper arm and upright scapula leads to bunchy shoulder musculature. The scapula is sandwiched at the top by two muscles: the trapezius...that the Bull-type head must of necessity be carried with a Bull-type neck, accompanied by a body built to carry it, and that, in turn, on four well-boned legs. This all goes to make weight, and when our maximum is 38 lbs., we have to be very sparing in size and build to obtain this....It is absolutely imperative that it be understood that the alignment of the bones from the center of the shoulder blade, when viewed from the front, to the center of the foot must be in one straight line, but it is not a vertical line. The same applies to the hindleg when seen from behind....The breed standard clearly defines ideal size, proportions, and substance which essentially tells us the proper balance between bull and terrier. Make no mistake; there is little room for personal interpretation of those descriptors, “deep,” “broad,” “wide,” “rather far apart.” The parameters of balance are handed to us in objective language, and our personal understanding...Symmetry is “balanced proportions.” It brings something into a pleasing arrangement. Dog judges with an “eye” see the dog as a whole. “Filling the eye” means no one thing out of place. Therefore, when the eye is drawn to a particular part of any animal such as rear, coat, front, or head, it usually incorrect…documented; suffice to say that straight stifles are undesirable and produce the all too common stilted action and invariably are a cause of knee and hip joint problems. Over angulation is also detrimental and places undue stress on the knee and hock joints, and results in the ‘bobbing up and down’ action and ‘crabbing’ movement....Sideways, the foreface is about as deep ast is wide. This type of head, with a good stop and set with neat rose ears, is the ideal. It can be quick to punish, with ease of movement. The circumference of skull should be about the approximate height at the shoulder. This should also coincide …”
