A man near us had a collie cross he said never needed a lead, as he wouldn't do anything without the owner's say so.
Poor dog was killed crossing an 'A' road near his home.
Another purebred Border Collie was being walked by a man after the dog's owner died- the Collie was walking up an alleyway but took off and ran into traffic.
I so often see off lead dogs on pavements- it's sheer arrogance on the part of the owner- the local veterinary hospital say it's always the so say ''well trained'' ones that bolt into traffic.
Trying to catch a bolting horse is hard- reaching for a flying rein is a sure fire way to make the horse spill your arm out of it's socket plus injure it's mouth-
This is an old video, but it shows how horses react when one bolts.
The idiotic screaming and whoooooooping and waving of arms does nothing productive.
The bolting horse wants to join his mates in the middle of the arena..it's carnage.
