water dog

dog used to the water, dog that is trained to catch waterfowl (Zoology); small floating cloud that indicates rain; old salt, experienced sailor, veteran mariner; one who enjoys being in water, water rat

Water dogs, once called Water Spaniels, are a type of gun dog and count among their number some of the oldest dog breeds. With the advent of kennel clubs many water spaniels were accepted under the names including the designation retriever rather than water spaniel. As the name implies, water dogs were bred to flush and retrieve game from water, often serving the waterfowl hunter. Strong swimming desire is a characteristic of these dogs.
