some one a few post back talked about all this info being lost when the old timers are gone . you couldn't be farther off the mark . all these breeders of bulldogs and game fowl have left their info in the form of knowledge that has been passed on in books and is still being taught to geneticist at the college level today . the American game fowl breeders worked hard and long figuring this stuff out and keeping records . of course most fowl breeders had dogs and horses as well these practices they used were heavily documented and preserved . a good read on genetics and breeding is [ the scientific breeding of game fowl ] by Floyd Gurley in it, it contains an 8 generation pedigree of Boudreaux's blind billy plus co-effiancy charts for the dog as well . so this info is out there but it gets deep and takes some studying to understand it lol .
10-4 on that...it is written and it can get complicated and confusing...so the best policy when breeding dogs is to breed the best to the best from within a family/line of dogs...the best defense is a good offense when breeding dogs...
