A dog was found tied outside Ayr railway station on Friday sitting next to a suitcase full of his belongings including food, a toy and a pillow.
The Scottish SPCA was alerted of the abandoned Shar-Pei crossbreed and went to pick him up.
Inspector Stewart Taylor said: “The dog is microchipped and we were able to find out his name is Kai.
“We contacted the owner registered to the microchip, who stated they had sold Kai on Gumtree in 2013. Unfortunately they could not tell us the address of the person who bought him.
“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.
“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. If anyone can help we would ask them to get in touch as soon as possible.
“Kai is around two to three years old and is a lovely dog with a nice nature. We will look after him until we can find him a permanent and loving home.”
Abandoning an animal is against the Animal Health and Welfare Act 2006 in Scotland and anyone with information should immediately call the Animal Helpline on 03000 999 999.
After Kai’s story went viral, a woman came forward to explain that she and her daughter were going to buy Kai after seeing an ad on Gumtree but the sale turn sour and Kai was left abandoned by both the seller and the buyer.
Kai was taken in by the Scottish SPCA and after a vet check, Kai was scheduled to receive eye surgery thanks to some £3000 raised by concerned donors.
“Kai was suffering from inversion of the eyelids, meaning his eyelashes were rubbing against the surface of his eyes and causing him pain and discomfort,” said senior animal care assistant Alan Grant.
“This is a fairly common condition among shar-peis.”
Kai underwent surgery on Friday and is now on a quick road to recovery and future adoption.
