As the owner of a large extremely well behaved labrador/Rhodesian ridgeback cross, I heartily agree with GUEST,not a dog owner. There is absoutely no excuse for bringing an unruly dog into a public area and especially not if there's a risk of it biting someone. And yes, dogs should be kept on leads at all times in confined spaces and away from places where food is being served. That is called responsible dog ownership.

But the vast majority of dogs are well behaved and friendly and do not make nuisances of themselves. Would anyone seriously consider a universal ban on people at festivals because a small minority cause offence by getting drunk?

Rather than banning dogs per se, why not ban the owners of any dogs who are seen not be controlling them properly?
