My family is raised in the Mid Coast area of Maine. This is where I live with my Danes and occasionally children. My dogs play area is situated behind the house. It's a 30x60 fenced in area with a 10x15 dog condo for protected rest or play. They can also enjoy the covered back porch to rest on, or enjoy their huge fenced in area to play in, but most of the time they like the couches in the living room of our home.
Consistency,Training and Socialization makes a Great Dane...even Greater.
