A few years back I read alot of material on linebreeding horses. An author "Robert Denmark" wrote a really good book I believe the title is " The King Ranch Horses". Robert Kleberg was trying to duplicate A horse named Ole Sorrel, Real good reading. But a little later I listened to a interview with Tio Kleberg, I believe Red Steagal was the interviewer. He recognized they were carrying it too far. That was when the ranch purchased Peppy San Badger, along with bloodlines of other top horses. I believe this goes to show whether its linebreeding or inbreeding, watched carefully can be a good thing. But the time for the outcross can always be expected. Also and I DON'T know this for sure, but always heard of the King ranch driving herds of bad horses off the ranch. Like I stated I don't know for sure, but it would make sense. Breeding horses in this fashion has always been a good debate and I'm sure it will be the same with dog breeders!
yes they bred old sorrel get every way you could cross them ,i think Mr San Peppy was first that is peppy san badger sire
