A dog found in a Sheffield park with a microchip registered to a Spanish address will be passed on to the dog warden if the owner is not found by today.
The male crossbreed, nicknamed Zorro, was handed in to Hunters Bar Veterinary Clinic after being found by a woman in Bingham Park, Sheffield, yesterday.
LATEST- Lost dog found in Sheffield with Spanish address on microchip reunited with owners
He has a microchip but it is registered to a veterinary practice in Spain and the vets have been unable to find the owner.
The clinic is unable to keep dogs for longer than 24 hours and will pass Zorro on to the dog warden if the owner does not contact them by lunchtime today.
The dog could be rehoused - and then would not be able to be found by the current owner - if he is not claimed from the dog warden.
He is wearing a brown leather collar with no tag.
A post by Thornberry Animal Sanctuary to help Zorro be reunited with his owner has been shared more than 1,200 times on Facebook.
Jay Constantine, a receptionist at the Hunters Bar clinic, said: "Ensure that you have microchipped your dog as early as you can do and keep those details up to date.
She added: "Spread the word about this to people who do not have internet access and may not know that microchips are now a legal requirement in England."
