A sweet-faced Scottish dog was abandoned at a train station with a suitcase full of its belongings, sparking an outpour of sympathy and numerous offers to adopt him. The dog was tied by a leash to a railing outside the Ayr railway station, southwest of Glasgow, a day after New Year. He was seen sitting next to the suitcase, seemingly waiting for his owner to return. The zipped-up suitcase contained a pillow, a toy, a food bowl and food. The Scottish SPCA, which was alerted about the case, said in a statement that the dog’s name was said to be Kai, a shar-pei cross breed, and that he is two to three years old. “Regardless of the fact Kai was left with his belongings, this was still a cruel incident and we are keen to identify the person responsible,” the SPCA, or Society for the Prevention of Cruelty to Animals, said. The charity said police located a former owner of the pet through a data microchip embedded under Kai’s skin. That owner had sold the dog last year to another person who could not be located.

Unfortunately they could not tell us the address of the person who bought him,” Police Inspector Stewart Taylor was quoted by the SPCA as saying. “This case highlights the potential consequences of selling an animal online as it often leads to the impulse buying of pets that people know very little about,” the charity said in a statement on its website. Kai “is a lovely dog with a nice nature. We will look after him until we can find him a permanent and loving home”, it said. A few of the 1,889 people who read the SPCA’s post on Facebook offered to adopt the dog themselves. A video posted on YouTube showed Kai being cared for and fed by a handler. Kai would lift his paw on the caretaker’s hand to ask for a piece of kibble. Abandoning an animal is illegal under a 2006 Scottish animal welfare act. Offenders can be jailed or be banned from having pets.
