Dave,

"And has anyone else noticed - none of these perfectly-behaved-dogs-with-extremely-responsible-owners-that-go-to- folk-festivals-and-are-loved-by-everyone - none of them - not one - ever barks?"

It's true, paragons of dogism I'd say. As for foxes we only have Urbane Foxes in Manchester and they wouldn't be seen dead at a Folk Festival on the grounds of dress code alone.
