We raised dalmations for about 10 yrs. Don't recall the bloodlines anymore as it was about 12-13 yrs ago. We'd have the occasional puppy with a blue eye, which supposedly went with being def. Never did have any def ones though, must have been lucky I guess. We used to get a few that would have a solid black patch on their eye or a solid black ear. It's funny that when we started raising them, the brokers wanted the ones with the black patches, then they remade the 101 dalmations movie (which by the way had several with patches) and then the brokers claimed they couldn't sell them. I think it was all a big hoax.
Anyway, of the 3 males and 4 females we had through the years, we never had a dumb one, and we never had an aggressive one. Always had other dogs running with them, so I can't really say that they were territorial either, as they always got along. They are fairly high energy dogs (some people mistake this for dumbness). They are obsessive tail waggers and will catch you off guard with a hard slap to the thigh every once in a while with their tail. Ours were alway good guard dogs as well. Well maybe not guard dogs, but they'd let you know if someone pulled in the driveway long before they pulled up to the house.
One more short story. 2 of the females that we raised pups out of, we got from another breeder down the road. Somewhere in their lineage they picked up the "smiling" gene. The UPS man would not get out of his truck because he thought they would bite him, but they were just smiling. They'd run up to his truck, tail wagging and show all their teeth in a big ol smile, never growled or anything. We were a caught of guard the first time they did it to us too, but then we got to where we could talk to them and get them excited and get them to do it when we wanted them to. It was great entertainment, and I don't know how many of my friends were scared to death of our dogs until I told them what was going on. :lol:
