Where does this color come from, when I look back at old school dogs I haven't come across any trios. My boyfriend thinks that it was bread in to the bully breed with rotts, but I don't know any thing about the color. Does any one know where the color came from in this breed? Also does any one know what a lilac trio is? I've seen people advertising them but they had no pics. It sounds pretty but no pics make me think there probly just blue trios, can any one show me a pic if it is a real color?
