Amazingly, with such size and power they are reserved and gentle, well adept to living among people, small children and other small animals.   Tall, muscular yet streamlined, powerful and graceful, the Great Dane breed dog is a real attention getter. The Great Dane breed dog thrives as a family member, always up and alert participating in the families day-to-day routine. Looking for a back-yard beast to keep people away, Great Dane dogs are not for you. The Great Dane breed dog bonds with its human companions, is energetic outdoors and requires minimal exercise. Usually a few times a day in the yard and then back inside to watch TV or lay at a sunny window. A Blue Merle is not breedable or showable.
