I have a pure white, 40 kilo (all muscle) boxer. I won't place a pic', I've been tempted to have him as my avatar on a number of occasions but it's just too much information.
They've banned the pit's over here a while ago now, under the dangerous dogs act. Still plenty of them about though, and cheap. Thing is that the breed is so hard to define, most owners get away with it by claiming them to be irish staff's, things like that.
