The whole story is a bit of a long one, but in short:
Saturday evening about 7pm I found a stray dog wandering near home. No collar. Very happy & friendly though.
I took him home, phoned the dog warden, and in the meantime my wife put a message & pic on the local community facebook page.
About half an hour later the owner turned up on our doorstep without us giving out our address.
My wife found this quite frightening.
Can you work out an address from Facebook ? The only thing we could think of is that my wife’s profile pic is of our Akita who died last year, he was quite distinctive, so anyone who’d seen him around may have known where we live and put 2 & 2 together. Seems like a stretch though.
