Whilst I wasn't at Shrewsbury (and not a dog owner although I grew up with a dog always in the family) I'd like to say that even the best behaved and even tempered dogs can snap when surprised or stressed. Many young children (and not so young) almost seem to think that a dog is like a teddy bear: you can play with it how you like with impunity. A dog owner, even with the dog on a lead, cannot prevent every child pulling or treading on the dog's tail for example.

I'd vote for dogs on leads at all times and not allowed in concert/dance venues (and perhaps muzzled?)
