I have an Eli male that's a house dog. He's been all go since a pup. Was kinda worried about attempting to make him a house dog instead of a yard dog at first. He's house broken and knows he can chew his bones and nothing else. He can be wild and hard headed in the home. At least 20-45 minutes of exercise a day curbs that and makes him calm. Sometimes exercise twice a day. The more the better. Its important for me to read when he needs to unwind his energy. I don't mind it. We walk/jog together a lot and it keeps me in shape too. He's still young and I'm hoping as he matures he grows out of it somewhat. He's supervised around the kids 100 percent. He's calmer around them. But when I get home from work he gets all crazy because he knows its time to work and release all the energy. Never had a problem with him biting or challenging authority.
