Kids, don't try this at home. My brother has a pitbull boxer mix and while I love him to death, I call him DBD which stands for "dumb butt dog." He's done many dumb things in the time that my brother has had him (and while I had him while my brother was in Iraq as a fire fighter), something tells me he would do something like this. In case you can't tell, this is an old swing set that has some sort of rope hanging off of it and the dog REALLY wants to swing. Since pits have such strong jaws, once he gets a hold of it, he can swing for hours. Like I said kids, don't try this at home. You don't have a mouth like a pitbull! lol
