i pulled this off an other fourm
dont know how true it is or acurate but he read for your self !
As for long haired dogs, most I have seen or heard of have Red Machine as the common denominator in the peds, and rumor has it JDJ used a St. Bernard in place of Red Machine in later breedings. I have also heard Red Machine himself was part St. Bernard, but not sure that is true, because some families down from him don't seem to throw long hair. JDJ's reason he couldn't have used St. Bernard was because there were none in his area at the time, yet there were (the place was crawling with St. Bernards), and one person on the JDJ board said maybe JDJ just didn't know what a St. Bernard was. Also, there is a tape floating around with a St. Bernard on JDJ's yard. I think that was early 80s. If anyone has that tape, I would love a copy.
