It also means the caravan park owner found the dog, didn’t really check around too much for NB (as the phone wasn’t found) took the dog to the SCHOOL, who then called PA. Who instead of thinking, oh the dogs managed to pull a fast one, I’d best go get her and give NB a ring let her know I’ve found her, calls the police, who instead of telling him to go look for his own girlfriend because finding the dog loose doesn’t mean much of anything, go to the river and find her phone.
All of that sounds… asinine.
