I hate to pile on, but I also witnessed a Pit Bull lock up on someone. We were at a neighbor’s house when I was a kid and their very friendly and nice pit was just chillin when one kid started chasing after the dog owners kid (just playing tag or something) and the pit sprang into action and latched onto the kids leg. It took a good minute to beat the pit off the kid and he had to be rushed to the hospital. The Pit was just trying to “protect” his owner, but it goes to show that you can’t look at these types of animals and assume they know the difference between play time and kill time. I would not let my kids around a Pit. No way.
I don’t see us ever having a dog or any kind of pet as we are just not home enough to give them the attention they need. I do like playing with my friends dogs though!
