Well, I'm as sure as I can be of the parentage. I got Koji from a rescue, Georgeanne's Homeless Hounds, in Brookesville Florida. All I really have is her word. I have even called her back and asked her if she was sure about the parentage. She swore up and down with absolute certainty that the breeder she got the litter from ONLY breeds aussies and berners, and there's no question. But really, all I have is her word, and I don't personally know her. I was able to find pics onling of all black aussies, but certainly not berners! It's a bit mysterious! The story behind how and why we got Koji is kind of long and would be boring to anyone but us, I think. He's 17 weeks old now, and is super smart, laid back, and very sweet. His nickname around here is "The Fatness", and I wonder if his belly weren't so big if maybe his legs would look longer! He's growing well and gaining about 2 pounds a week. He's 23 pounds as of a couple days ago. His legs look a bit longer than when I took the photo in the avatar, but he may not end up being the leggiest pup on the planet! I'm curious to see what he ends up looking like, that's for sure! Oh, btw, it doesn't show in the pic, but his hair is kind of medium long and wavy on his back.
