Spaniels definitively fall into two types: ones that seek prey in water and others that seek it on land. Spaniels are the oldest class of gundog in existence, going back at least to the late Renaissance. Flushing spaniels combine hunting, flushing, and retrieving skills. Flushing spaniels that are used in the modern field include the Brittany, the English Springer Spaniel, the slightly smaller Welsh Springer Spaniel, and the field bred American and English Cocker Spaniels. The larger two chiefly are used for retrieveing and flushing game in thick grass or mild underbrush, with the Brittany having working habits closest to later developed pointers. Cocker Spaniels are generally used for thick prickly brush that they can duck, dive and dodge in pursuit of smaller game like rabbits, and Clumbers, Sussex, and Field Spaniels are preferred for their slower, methodical hunting pattern.
The American Water Spaniel, Irish Water Spaniel, Kooikerhondje, and the Boykin Spaniel are noted for their water work and do very well in temperate water, with the last being adapted to subtropical swamps. They fall into the water spaniel category. Many of these breeds vary their game according to the desires of the hunter: American Water Spaniels are known to be able to go after animals as big as a large goose in the water or the much smaller prairie chicken out of the water. Boykin Spaniels have a coat more closely adapted to the warmer temperatures of the American South whereas Irish Water Spaniels are adapted for cool, damp conditions, hence the curly coat and whiplike tail of the latter.
