When I stop at the services, my first thought is: where are the toilets? Followed by how do I find my way out of this hell?
For a small dog, a service station is an alien planet of noise, feet and flapping crows raiding the bins. We'll never know why Bonnie (left) slipped her collar and vanished at Reading services west-bound, but she would have been more nervous than most as a rescue dog from Eastern Europe.
Her adoptive owners have mounted an epic social media campaign, gathering more than 1,300 followers on Facebook who watch and comment on the search as if it were a live soap opera. But, so far there's no sign of her.
It's a terrifying lesson for dog owners everywhere. If you're taking your dog on a long journey where you may be stopping at the services, consider putting them in a harness-type lead, and hold on tight.
And if you're in the area, watch out for Bonnie.
