Had not thought of the basenji 500 as a prewalk calm down! but the few times we have been to friends homes who have a fenced yard (ours is falling down, getting it fixed Soon), and OoZoe calms right down. She will Not wear a gentle leader. Though she has come a long way from the skinny frightened 4 1/2 yr old almost 2 yrs ago! Thank you for the insight!
