Their eyes are large, expressive, and typically dark, giving them a soulful look. The ears are set high and are either erect or slightly tipped, adding to their alert and lively expression. Their coat can be smooth and shiny or long and flowing, with a variety of colors including black, brown, and blue, often with tan markings.
