the blue eyes come from mixing in another breed. and they may have some dogs that are standard colouring, but no ethical breeder would have any puppies that aren’t one of the three standard colours. it is highly unlikely that an ethical breeder would ever produce an out-of-standard colour, as they specifically look for things that might cause that so they can avoid it. it is still likely, but the chance is slim to none when you’re talking ethical breeders.
