I handed the dogs into the RSPCA.
They ascertained the owner through their microchips, then they knocked on their door, rang on their bell, and tapped on their window too. All to no avail. The owner did not respond to the RSPCA’s efforts to contact them, so after the statutory period, they were officially classified as surrendered.
To cut a long story short, the old boy, going on twelve and the younger but not young girl, going on nine, couldn’t be rehomed together.
Rather than separate the dogs, I’ve taken them both in and given them a retirement home. After a good cleanup and with some ongoing geriatric veterinary care, I think Feral and Cheryl can now look forward to a few good years.
They’ve settled into my place as if they’ve lived there all their lives and seem to be happy and comfortable. Thanks to everyone who cares.
