Roger is a very dedicated breeder... I am sure you will end up with a good dog. He's also a wealth of knowledge in how to raise and train a dog. Make sure you get his DD Puppy Manual. I don't have DD's, but thought his book was extremely helpful for anyone who is getting a dog bred in a JGHV based breed club. Very helpful in understanding the importance and process of testing the pup next year in VJP and HZP.
Good luck with your pup.
