Tadhg left his car to close the gates and Otis, a miniature Dachshund, stepped on the 'lock all doors' button beside the driver's seat, leaving Tadhg outside.
"I came home and left the car running while I went out to lock the gates and Otis stepped on the “Lock Doors” button," Tadhg told us.
"I actually couldn’t believe it and there he was sitting in the seat looking up at me. So as I was thinking of a way back in the cows from the field next door heard all the commotion and decided to pull up and watch.
"You actually couldn’t write it like...So I ran back and forth calling him to see if he’d press the button again with his paw and eventually he did."
Tadhg filmed his attempts from outside the car to get Otis to unlock the doors, and they are hilarious.
