The other side of the ‘ gentle giant’ coin is that wolfhounds thrive on attention and affection. They do best when they have status in a pack and a human family is a pack to a wolfhound. So, it is greatly preferable to allow them into the house and also to sleep inside like the rest of the pack. If they have to be left outside for part of the day they must have suitable shelter, such as an outside room or shed with bedding and, preferably, a canine companion.
Wolfhounds do not cope well with being left outside full-time. If this is your intention, another breed would likely suit your lifestyle better?
