Learned something new today

The White police horse dropped one right outside our turn style just as we were going in .
I jokingly asked " why do you not need to pick that up "
She was obviously a jobsworth and took the nip. Translated from Scots, took the huff.
She replied "this is a working animal so they are exempt"
Anyone got a spare sheepdog I can borrow, just to test this like!!!!!!!
