Easily trained, these are guardian dogs by nature. They descend from a mastiff-like breed and have been used, throughout history, to protect estate and carriages. They usually are friendly with children and other pets, but some individuals may be stubborn. It is important to give great Danes obedience training at a young age to make them somewhat manageable at later stages in their life. Some dogs of the breed can be aggressive towards unfamiliar dogs. They are playful with children and protective of their families.

 Great Danes are large dogs and shed light, but they need open spaces for the full development of their personalities. When they are puppies, they like to be free and to be able to roam around. They eat a lot, so be prepared to spend a considerable chunk of change on their diet. These heavy droolers come in a range of colors: black, blue, fawn are some of them. They have long necks just like their bodies, but their body is more muscular than the neck. You can either get their ears long and floppy or short and erect. Owing to their large bodies, they are prone to life-threatening problems like bloating, which is the building up of gas in their stomachs that leads to twisting the stomach.    

They do not have high threshold endurance or high amounts of energy. They are playful amongst children but won't go out of their way to do silly and cute things like some other dogs.

They do not require heavy exercising daily, but 10-20 minutes of walk or some other physically engaging activity is necessary to keep them fit.
