The Irish Water Spaniel is the tallest of the spaniels, easily recognized by its coat in small, tight curls and its thin tail, called a "rat tail". It is an excellent swimmer, a diligent and brave hunter and a playful and affectionate dog at home. Wikipedia says that it is also called the "clown" of the spaniel family.
