To the chap above ^^
Don't use the word 'we' so liberally. I wouldn't condone allowing people to own these dogs and am all for hosing them if they attack someone.
My next-door neighbour lets his dog out at midnight and beyond sometimes and I have to listen to it barking. While he's probably the minority, he's a great example of why dogs should be 'uninvented'. Along with guns, I suppose.
