I have gotten several dogs from Dan, and also traded a dog with him that was a horseback dog that my dad couldn't keep up with, and my dads dog he got on trade was the best pointer pheasant dog I have ever hunted over. He is a solid guy, a good trainer, and knows what he is doing with his breeding program. That video on his puppy page is of my pup when she was 10 mos old. I knew him back when he was in the business world and breeding as a side business, solid guy back then in the mid 90s from a business dealings perspective as well. From what I have seen, Rock Star Andy crossing with his various matrons seem to be throwing off fast starting, smart pups.
PM me if you have any specific questions.
