If snatched up in the air, it maintains the basic crouched posture. Most owner manuals advise dog ow^ners to use nose contact, circling and pivoting as clues for a "forthcoming accident" (Wilm- hurst, 1955). The other situation involves "turning around in a circle" several times before lying down to sleep. Darwin referred to this behavior, citing it as an instinctive action performed "in Vacuo," without any obvious function. Konig (cited in Trumler, 1973) reported that the amount of circling is positively correlated.
