In temperament it is eager, cheerful and intelligent, keen to work and affectionate with its family, though it can be reserved with strangers. It remains an uncommon breed.
It is a sturdy spaniel with a broad head and a dense coat that ranges from uniform waves, known as marcel, to close curls, in liver, brown or dark chocolate. The moderately long tail is moderately feathered and carried in a gentle rocker-like curve, and the eye colour tones with the coat rather than appearing yellow.
The American Water Spaniel took shape as a working gun dog for hunters on the rivers and marshes of the upper Midwest, and its story remains closely tied to Wisconsin. Its ancestry is not documented, though the Irish Water Spaniel, the Curly-coated Retriever and the extinct English Water Spaniel are often suggested as contributors. In the late twentieth century Wisconsin adopted it as the official state dog. It was bred as an all-round hunting companion. It was compact enough to ride in a small boat, and it retrieved waterfowl from cold water and flushed and retrieved upland game on land.
