My opinion is that no reputable breeder intentionally breeds mixed breed dogs. There is just no purpose to it. When breeding purebred dogs, you are breeding to a written standard. When breeding mixes, there is no standard to breed to - you are just sticking a male and female together and letting them create puppies and who knows what the puppies will turn out to be like. These "designer dog" breeders are not trying to create a new breed - they are just breeding two dogs together - creating a new breed takes years and years of work, knowledge of genetics, and a lot of planning when breeding - you have to know what qualities you are looking for and breed toward that (basically breeding to a standard).

That being said, I have seen two full grown yorkie/shih tzu mixes recently. The first was probably about 9lbs. she was a reddish-golden color with a silky coat - very fine hair texture. She had floppy ears but they were pointy like a yorkies and not round like most floppy ears are so they looked a little funny. She had a longer muzzle more like a yorkie but you could see the shih tzu look to her face. The second one was a smaller dog - probaby 5-6lbs. She had a short muzzle (not as short as a shih tzu - the "baby doll" face like some yorkies have). She didn't really have a "shih tzu" look to her face. Her hair was more cottony in texture and she was also a reddish-gold color. I can't remember right now what her ears were like but this one was a cuter dog than the first one. With a mixed breed - you just can't be sure how they will turn out to look.
