Eimear O'Donnell was at home in Leitrim with her brother Seán when their Golden Retriever, Beau, decided to stir up some mischief by stealing Seán's phone.
Seán tried to get it back but Beau took the opportunity to have a little fun.
And a very funny standoff between man and dog began - Seán wasn't that amused but Eimear helpfully got the whole thing on camera, posting it to Facebook with the caption:
“The world’s worst dog… and I still wouldn’t change him."
Her brother tries his best to be stern, chases him, tries to tackle him - but Beau is having the best time and he's not giving up his new toy.
In a second video posted in the comments, Eimear tries to help her brother out, advising him to hunker down and 'entice' him in.
But to no avail, as the dog leads him on a merry chase through a hedge.
Look at that face though! You couldn't stay mad at him.
And he did give the phone up
