What if the dog isn't at all bothered by the 'noisy environment'? I always took a dog with me when going alone to Oxford, Wolverhampton, Peterborough, Coventry or Leicester. None of them have ever shown the slightest concern about noisy motorbikes, in fact quite the opposite as they just went to sleep on a blanket while the match was on. Border Collies too that are supposed to be lively.
