I have a worse story, but it was in the days before chipping dogs was common.
BFF was barn manager at a big showbarn close to a suburban area. One day, a very nice looking intact male Lab shows up at the barn and just starts hanging out.
Clearly someone’s dog, clearly purebred, polite and well behaved around the horses.
Doesn’t leave.
BFF calls around to animal control, the local shelters and vets. Tells animal control and the shelters she doesn’t want them to pick him up, she just wants help connecting with his owner if the owner calls in looking for him. (This is where I think it went wrong. I think if she had surrendered him, the owner would have likely found him.) She did also put up found dog signs all around the neighborhood.
Weeks go by, no one contacts her.
Significantly, the dog becomes a happy farm dog, is allowed free range of the farm and doesn’t leave.
BFF then says, okay, guess I’ve got a new dog. Takes him to the vet to be neutered and have his shots. Tells the story to the vet, vet agrees that the dog is abandoned and neuters the dog.
Another month passes.
Angry man shows up at the barn WITH A SHERIFF’S DEPUTY. It’s his dog. Dog escaped from its kennel and found the barn. Angry man claims he called animal control and local shelters. I believe him. I think he called, the told him they didn’t have the dog but nobody remembered to say “Hey, there’s this girl at the local barn who called in about a dog that sounds like yours.”
A friend of his showed him one of the “Found Dog” posters and he showed up at the barn. (Sign had a phone number, but also Contact BFF at Blankety Blank Farm. It was the days before cell phones and microchips, sensible way to post contact info for a farm girl.)
Angry man threatens to sue her for neutering his prize stud dog. Leaves with dog after a lot of threats and posturing.
BFF is crushed. Does not get reimbursed for months of dog care, obvi.
Dog returns to life in a kennel rather than a happy barn dog.
Angry man still angry. No one happy.
