The American Water Spaniel was developed in 19th-century Wisconsin as a compact hunting companion that could work from a small boat, flush birds and retrieve from cold water. It's Wisconsin's state dog and still an uncommon sporting breed. Males run about 30 to 45 pounds and females 25 to 40, with a curly or marcel-waved coat in liver, brown or chocolate. The oily double coat sheds water well and sheds moderately, with heavier seasonal periods.
In Denver, that stamina and water-loving streak mean a dog that wants more than a lap around the block. Many are affectionate with family, reserved with strangers and sensitive, so calm, reward-based training works best. Some bark at hallway noises or visitors, which matters in apartment buildings. They mature slowly, often taking two to three years to settle.
