My grand niece was given a Shih Tzu when my nephew (not her father) had to down size.
The dog is very noisy, barking loudly at all noises he thinks might be caused by strangers.......including my car, every time I drive up. He barks at all delivery vehicles, until the driver gets out. Once strangers get close enough to touch, he loves everybody.
In the house, he gets to the highest place he can, and lays there. The back of the sofa nearest the front door is a favorite perch.
Thar is so funny. Our Shih Tzu doesn’t bark - EVER. It will yip/growl when I play with it, but otherwise never makes a sound.
