Stile for Wychnor dogs

A special stile for dogs in the countryside is a new one to me. This one, by the canal at Wychnor, means that the dog in question does not have to clamber over the stile, nor be carried over it, nor slip through some other way..
It works quite simply. You see the red handle on the left? It is attached at its end to a 'paddle'. When you raise the handle, up comes the paddle, and the dog slips through the hole.

I'm vaguely amazed. I was aware that we now have man-made under-road ramps to enable hedghogs to cross country lanes safely, but ... stiles for dogs ... Never seen those before.
