Great story. Dogs are amazing. I know that sinking feeling first hand.
Last year I went out back to lock up the hen house for the night, and it was dark so I didn't realize my bulldog followed me through the gate to the back pasture. I came back and closed the gate behind me, and went in the house to watch some TV, all the time thinking my bulldog was just hanging inside the fenced yard around the house. But it was unusual for him to stay out more than an hour, so after a couple of hours it occurred to me he hadn't scratched to come back in. I went out into the yard and called and searched. Nothing. He wasn't in the yard.
That's when it occurred to me that he must have followed me out back to lock up the hen house. He must have tried to get back in, but couldn't get past the gate.
Now, there's also a fence around the back pasture, but not one that would be any trouble for him to get out of, so he likely gave up on the gate and started to find another way out, which took him to the streets. I drove around and around, heartbroken. Couldn't find him. Finally gave up, and went home, thinking first thing in the morning I'd call all the vets and shelters.
Well, just then I got a text on my cell phone from an all night vet clinic saying they tested him for a chip, found it, and called the number on it. They had him. They said a cop brought him in. So a cop must have seen him wandering the neighborhood, called him into the truck, and drove him out there to be chipped.
So I can well understand the sinking feeling that guy had when he realized his dog was gone. I thought I'd never see him again.
He's the one on the left.
