My weirdjack experience is very young. I got a pup from the source. He is 6months and is the most confident, intense, focused, strong & workaholic pup I ever seen. Plus he is smart with beautiful confirmation. I became interested in this line from researching and finding out that their key traits were finish, power and athleticism. They are extremely early starters too, so you have to be very careful with them. But all in all, so far, so good!
