Here is my experience with this. Many years ago I bought a teacup poodle from a lady from Germany that had showed these little dogs for years. She bragged about the breeding (inner breeding) saying it kept the line pure etc. My little Tia was a cutie but I think she was crazy! I didn't know any better at that time that it could do things like that. I ended up having to put her down by the time she was 8, I should have done it earlier but I loved her and put up with her until I just couldn't anymore! She had really odd behavior and would do things like lick the air. She would try to bite people when they came in then would love and kiss them a minute later, then try to bite again. I DO think her odd behavior came from the inner breeding.
