I was standing at our gate and watched a lady fast walking past me while yelling at this dog. I thought it was hers and was naughty. She said, 'is this your dog?". I said, "no" and then the dog saw me and ran into our property. She then said, 'Well she is yours now"!
She was a farm dog, I thought and she followed me inside. I found a chain that would work around her neck and she sat down on our sunny deck, quite happily! I found out to ring Dog Control and shortly after she trotted happily alongside the lady to the van.
I wish I knew what happened to her.
