I have a 2 year old female fawn boxer. Her name is Chaos. The other day I got her a duck toy from Petco. It is a duck head on a loop. Well I was walking her and got tired of picking up the duck head, so I attached it to her leash... She was walking with the duck in her mouth. Anytime she would drop it she would do a circle trying to catch it again. I believe I have found the easiest way to walk her.
