My son has two Shih Tzu’s and they are both very easy going and mellow. Some have a double coat, but many have the single hair like the Yorkie, so finding the right breeder would be helpful. I think they are the perfect dog for a child, who could give them big bear hugs with no problem, and they are on the list of hypoallergenic dogs.
