That is what I mean when I say the standard is a mess.
Some are born with a tail, some without. Those born with a tail usually have it docked where that is allowed - talk to a breeder and they can certainly accommodate your desire for a “Australian” (that isn't really) with a tail!
Some have brown eyes, some have blue, and one blue and one brown is also fairly common.
Blue merle with black points, red merle with copper points, and just about any other color scheme is perfectly acceptable.
They are super great dogs, although some are “too smart”.
Dogs can’t be too smart. It’s the smart ones which are the most fun!
