London, UK - Kai the golden retriever loves nothing more than a good cuddle, so it's no wonder he got so disappointed when passengers on a train rudely forgot to pet him!

A video posted by his owner on TikTok shows the handsome hound lounging on the floor of his compartment, getting increasingly frustrated by the lack of cuddles.

"My golden retriever everytime someone walks by us in the train and don't pet him," the caption reads, as people walk by without giving poor Kai the attention he deserves.

"Honestly how can you walk past him without petting him," the pooch's human asks, and it's a fair question.
