I fully agree with that, my dog is always leashed when outside and I keep an eye on her whenever someone new comes over. She is well socialized, not even the least bit aggressive with dogs of either sex smaller or larger than she is. She also is good with kids, I have a couple friends who regularly bring their small children over and they pull on the dogs tail and wrestle with her and she is gentle as a lamb.
I'm sure there are some here though that think she should be put down just because of her breed though.
If you maintain control at all times, fine. Too many owners don't. I never let my Lab loose except in the fenced backyard with me or wife watching her. She loves children too much. At 75 pounds she could seriously injure a child just running to greet them.
