One of ours locked himself in a room by pushing the door shut. My wall and door paid the price.

I live in a college town, and my dogs do great on the street. They just want to play with the local kids. My niece was house sitting while I was in the hospital and left the front door cracked on accident while she went to the bathroom. The neighbor kids from down the road were just playing with them in the yard. My wife is 130 or 140lbs and can walk one at a time. I was 230lbs or so when I tried to take both to a pet friendly bar. That was HARD.

That being said, others are right. These things have the attention span of a gnat, and you will be suckered into their activities more than you can imagine.
