thought i would add something else: my grandma has a shitzu, Tia. whenever tia decides she wants to take a poo, she will turn around and around and it seems like it never ends lol...i remember one time we took her for a walk, and we counted, and it took her 23 times before she finally just went to the bathroom lol...then she looked all proud of herself...funny little strangling dog...anyone else seen something like this?
