The owner of a dog found travelling alone on a train in Swansea is being sought by staff at RSPCA Cymru.
The sandy-coloured Chihuahua was discovered in a carry case by a guard on the Arriva Trains service from Manchester Piccadilly to Carmarthen yesterday afternoon.
RSPCA workers believe the dog to be elderly, but otherwise healthy.
Inspector Nic De Celis said: “There could be someone out there who is missing this dog and is frantic with worry and we’d really like to reunite them with their pet. But at the moment the reason why this dog was left alone on the train is a complete mystery.
“We are keen to speak to anyone who has any information, whether they noticed the dog while travelling on the train or if they know of someone who is missing a Chihuahua”.
Anyone with information is asked to call 0300 123 8018.
