If you get a pup. make sure you condition it to the idea of you leaving the house without it. The old man babysat a yr old 'pup' for 6 months for a friend of 'ours' and it cost him a fortune in custom made draperies and window blinds amongst other furniture etc. lol
The people that left it with him had not tried to train it whatsoever and it would rip the drapes AND rods right off the wall to see out. It also had a mind of its own... if it wanted you to go somewhere in the house, it would bully and push you to the place it wanted. (pup at 70+ lbs)
It was lovable tho and seemed to get along with his kids pretty well. The main thing that *I* didn't care for, was it would rest its head on your leg when you sat down and slobber all over ya! Yuck.
If I had to decide on a dog like that, I'd vote no. We have a half newf, half shepard that is HUGE, but he's been well trained and isn't a problem. Its costly to get that much training as well.
He's our backup to our backup alarm system.
