I'm sure our domestic pets (dogs, and cats too) haven't really left their instinctive behaviours behind, it's very near the surface. A farmer we know demolished an old rundown barn on his land, with the help of his two sons and numerous terriers. The rats apparently were streaking out from the debris in their dozens, but the terriers went wild with excitement and got the lot within minutes.

At the Norfolk Show, they always have a lovely turn where an entire Hunt comes into the arena, about thirty foxhounds, and huntsmen/women in red coats mounted on beautifully-groomed hunters. They sound their hunting horns, and the Whip controls the pack while they bay all round the ring. I know foxhunting is cruel and I'm glad it's been banned, but that is always a lovely sight at the Show!
