Very wide through the eyes, giving a soft round appearance, angles are blurred. Good width across the wedge, eyes tend to be rounder Moderate wedge has pleasing lines.  Eyes are oval or tear shaped.  Not round. Not almond. Narrower through the eyes, eyes start to tilt, change to almond shape Little difference in angle between muzzle plane and cheekbone plane, eyes often small
Notes:  As the width of the top part of the wedge widens, the muzzle also broadens in order not to create an exaggerated, pinched look.  When the head is too broad, the width in the muzzle adds to the rounded appearance and all angularity appears lost.  When the top part of the wedge, narrows, the eyes start to change shape and to tilt rather than being level set.  The muzzle either narrows to a point in order to maintain differentiation between cheekbone and muzzle planes or the two sets of planes start to blend together providing the appearance of a straight line wedge.
