I had a dog that was bred by Blue Sky. He was a good looking dog. Can't say anything else good about him though... I don't know if he is a representative of what Blue Sky produces, if he was a product of his upbringing, or if he was just a cull. I bought him as a 3-4 year old dog, I hunted him for a solid year, saw virtually no improvement, then sold him back to the guy I bought him from. He was dog aggressive and would not hunt out past about 30 yards....but did I mention he was good looking
I have a much different opinion of how to handle that type of dog today, than I did back then. Today, that dog would have been put down, or at the very least neutered so that he could not pass on those traits.
