Things have gotten really hairy for Ashton Kutcher on Two and a Half Men!

First, the star found himself in bed with a very engaged Miley Cyrus, and this week, he’s dealing with a Great Dane.

On Thursday’s episode, Kutcher’s character Walden Schmidt gets a very big canine for his girlfriend’s daughter – but he isn’t at all prepared to report for dog duty.

The brown pooch, which stands tall at Kutcher’s waist, starts wreaking havoc around Walden’s bachelor pad, tearing the living room apart.

In real life, Kutcher knows what it takes to keep a handle on furry friends. He acted as pack leader of five dogs when he went on a hike with ex Demi Moore’s daughter, Rumer Willis, in January.

Two and a Half Men airs Thursdays at 8:30 p.m. ET/PT on CBS.
