"Let's just remember this thread was started because a child was bitten at Shrewsbury Folk Festival and needed seven stitches.

It was a bit late throwing the owner out and the dog out at that point wassn't it? "

But I will say this again:

The question is where does it start. How many bites, infections or traumertised children before a ban? One, two, ten, a hundred? Make a reasonable decision.
