Great points, it is correct to say that P.Patrick dogs have played a role in the history of our breed. I must add that the blood is not as potent as it once was coming from his yard. And now after them NUTS eliminated a great majority of his dogs and puppies for that matter. However them cats at Imperios kennels are have a good amount of success with the blood. And Ca Jack is correct by adding the blood to Chinaman/Frisco blood is more like back to the future, without the De Lorean(did I spell that right?)
