What are some traits of Harlequin Great Dane puppies?

Harlequin Great Dane puppies have a marbled coat of black and white, floppy ears and a fast growth rate. A Harlequin coat is white with torn patches of black that may cover a large amount of the coat, or the coat may be mostly white, according to ChromaDane.

When young, Great Danes are a boisterous breed and are prone to jumping up in excitement when their owners come home, according to yourpurebredpuppy.com. They require a moderate amount of exercise, but too much can damage their growing bone structure. This can leave them with an excess of energy which can turn destructive if they become bored.
