I'm looking at J-Nels SQ Donnie who is ADGA reg. they don't show his sire. Yet according to the breeders site his sire is rosasharn's ss sequoia (so at first I thought maybe he was AGS). When I look on ADGA pedigree under Rosasharn's ss sequoia he is ADGA but under his progeny he doesn't show J-Nels SQ Donnie. Does anyone know why it would be listed that way??
