we've recently moved into a neighborhood where there are tons of big dogs. I can walk by the big dog's house and they just sit in the window or on the grass and do nothing. my dog, the miss priss that she is, will bark at those dogs. She will bark at most people walking by our house, she will bark at our neighbor when he walks into his back yard. I need to know if this is just my dog, or yorkies in general, or even a tiny dog thing??? any input would be great! thanks so much
