I have Hungarian lines..Sue mentioned Durrer (not sure if she thought they were Hungarian, cant' tell by the post), Durrer is a Canadian line. My Foster is out Mandy and Sultan, He's my Hungarian/Canadian boy!
You can go to mywebsite and see Mandy and Sultan and Foster.
As for selecting lines. I have to say, you want to select the Yorkie for it's structure and representation of the breed not 'line shop'. Don't buy something because of the 'lines'. They can be a bonus but not the sole purpose for buying the Yorkie.
Good luck!
