Boisvert found a safe place to pull to the side of the road and got out his rescue equipment, which, apparently, no animal lover leaves home without.

"I ran down to the ditch and pretty much did a jump and scooped her up in my arms quick - before she even had a chance to know I was onto her," he says.
