Well, I am interested in hearing some of the responses to this, as my 2 year old yorkie female is not nice to other dogs. She has had labradors cowering on the ground. I want another dog, a small yorkie (she is 9 lbs) but I am afraid that she will hurt it. I think eventually she will play with it. My sister in law has a daschund, and they recently got a chihuahua. He was very mean to it for about 3 months, and avoided it like the plague, now they play together very well. Good luck, and I say don't listen to the psychic.
