I've had one for 5-6 yrs now. Have to train them reallllly early for potty train. And if the get excited or whatever no matter what they will piss on the floor lol. Mine will bark for a bit then i just open the door, he runs outside, handles his buisness and runs back inside . Very good with children and very playful even after many years I swear mine is a cat sometimes. If he was a she I would be all over that Yorkie. $450 is an awesome price for this puppy.
