From everything i used to read about WGSD is that thery were more aggressive, but maybe it was just the trainers at the time diddnt like white? IDK. BUT my Zero is by far the sweetest giant i have ever met, his dad was a king white shepherd who was nice and friendly and his mom was very timid but sweet. he had two other littermates who were very shy and diddnt like new people but Zero greeted me with a wagging tail so he was who i picked, he is very protective of me, maybe a little to much but hes such a cuddle bug that i love it.
