Yup - I think once "dog people" find their breed, that is IT for them. My brothers and sisters ALL have something different (I have 4 - 2 brothers, 2 sisters)
One sister is into Westies, she has EVERYTHING Westie and is learning how to breed. My brother is into Poms and one of his had her first litter a couple of months ago (sadly, only one survived

), my other brother loves his mutts, he keeps offering me insane amounts of money for Sandy! -- my other sister loves her simease cats! My parents WERE Yorkie people, but switched to Lhasos after they retired.
And I am carrying on the Yorkie tradition and hope to be the first in our family to show dogs
