Is a Great Dane right for you?

Before making the decision to purchase a Great Dane, ask yourself the following questions:

  • The Great Dane is a giant breed that takes up more room in the house, needs an appropriate sized car to ride in safely and will cost considerably more to maintain than a small breed. Have you taken all this into consideration?
  • A Great Dane, especially a rambunctious puppy, can knock down a small child in play. A Great Dane must never be left unsupervised with small children.
  • A Great Dane can be very destructive to your furniture, woodwork, garden, and personal belongings. Are you prepared to deal with this?
  • Big dogs have big medical expenses and require the same amount of medicine as an adult person. Are you prepared to purchase canine health insurance or face huge bills in the event of a health emergency?
  • A Great Dane MUST be obedience trained to obtain control. Are you willing to put in the time and effort to train your dog properly?
  • The Great Dane is a sociable, friendly breed. Great Danes needs to have human contact, affection, regular socialization with other people and animals, and firm, consistent training. Are you ready to provide this?
  • Great Danes require exercise appropriate to their age. Many do not “self-exercise.” Are you committed to providing proper exercise in all types of weather?
  • Great Danes have good noses and many have a “stubborn streak.” When not on a leash, they need a fenced yard or they may “follow their noses.” Can you commit to putting up a sturdy, appropriate fence?
  • Great Danes can be excellent companions for almost any activity you wish to pursue including jogging, but you *must* wait until after your pup is two years old to avoid damage to growing joints. If you are looking for a puppy, are you willing to wait for it to grow up?

Unless you can answer yes to ALL the above questions, then a Great Dane is not the dog for you.
