Though they will rarely bark unnecessarily, they will not hesitate to be vocal if a threatening situation (such as the presence of an intruder or trespasser) presents itself. The Leonberger is eager to please and responds well to training. Its temperament is suitable for children of all ages, and unlike many larger dogs, it will not normally dominate people or other animals. The Leonberger will do well in an apartment if it has plenty of opportunities to exercise or play in a large yard.

Its coat color should be golden-yellow to red-brown, with a black or dark mask on the face. The coat will require weekly brushing and Leonbergers should only be bathed when necessary. He is a seasonally heavy shedder, and while shedding, it should only be brushed and combed once daily. Its coat should be medium-soft to rough in texture and long, sleek, and not too wavy. Although waviness is allowed, the coat should never be curly. The Leo has a beautiful mane, which will develop between the ages of two and three.
The mane and feathering on the fore- and hind legs and the underside of the tail may be lighter but should blend well with the main color. The color of the tail should be the same color as the body coat and “badger-colored” tails are allowed.The Leonberger is a big dog with few drawbacks for those who enjoy big, fun-loving, active dogs.
