Pet dog ruins owner's birthday surprise by pawing at her cake

This is the hilarious moment a pet dog ruined its owner's birthday surprise by pawing at her cake.

Video shows the seven-year-old pooch named Roger sniffing at the woman's cake as she held it close to his face in their house in Khon Khaen province, Thailand on December 14. Unfortunately, excited Roger inadvertently dropped the cake to the floor when he swiped at it with his paw.
