 To a casual observer, the Kuvasz may appear similar to a Great Pyrenees, Akbash, a Maremma Sheepdog, Slovak Cuvac and the Polish Tatra Sheepdog, all of which are similar in size, coat color, and general appearance.As with many livestock guardian dogs, the color of the Kuvasz's coat serves a functional purpose and is an essential breed criterion.Shepherds purposefully bred the Kuvasz to have a light colored coat so that it would be easier for the shepherds to distinguish the Kuvasz from wolves that would prey on the livestock during the night.
