They'll work the heaviest cover and have decent noses as a breed. They handle the cold well and are good swimmers; they have an undercoat and webbed feet.
They're a typical German breed...hard-headed but not difficult to train, and they are a reasonably intelligent breed. As a house dog, they have a distinct odor.
If you give them frequent baths don't send them into cold water. That odor is from oils that insulate them.
