Yatzy is my daughter Maria's dog and she knows him best....
For me, he is very much alike his brother Moltas in many ways, but maybe a bit more weaker, which make it easier to handle him and get eyecontact... He is also a bit more balanced in his way to meet humans... More like his mother in temperament, but his outlook is a very good mix of the two.
Yatzy has his own homepage where you can see more photos of him, the text is still only in Swedish though: http://hem.passagen.se/larwass
