I don't mind when my boys bark to alert me to something, as long as they stop when I want them to.
I do mind when they play their barking game in the car. It's like "spot the license plate." They bark at school buses, motorcycles, UPS trucks, and large trucks. The problem is Max could win a contest for loudest, sharpest Yorkie bark on the planet.

He knows the power of his big voice, and he loves showing off.
I'm thankful that Max doesn't bark all day because he is way too loud.
