There are a lot of not so good ones and there are good ones.
I have a little female who is 5 months old and she is everything a chi should be, sweet, loving, playful, thinks she is bigger than she is, loyal and quick learner. She is a white with grey longhair.
I have been looking on the KC web site at litters on there as I am thinking of buying another. That seems a good place to look.
