My sister in law took it in and then got pregnant. SIL quote a while back when I expressed my concern was "We take all precautions...we don't even trust the dog with our new baby".
When we went to visit with our 2.5 year old boy and 10 month old, my little boy kept saying "Look dad, there is bad dog" (I had coached him on staying away).
My SIL was pretty pissed that I had taught my son to fear that dog and call him "Bad dog".
I had told her that the gun I brought to CA was not for protection, but to kill her dog if it so much as growled at my children. I had told her to board it or let someone take care of it while we were out there for a week, but she kept coming up with excuses on why no one would take it in for a few days.
Anyways, Lesson learned. We will stay at hotel from now on when visiting her relatives. I was dead serious that I would kill that dog without blinking an eye if it did ANYTHING hostile towards my children.
My wife and I had a stressful visit simply keeping vigil on where that dog was at all times.
A friend of my dad's owned a pitbull. He had it for years, then one day the thing attacked him without provocation and clamped its jaws over his face. They had to kill it to get it off him.
