Dwayne Johnson My Bulldog Pup Sank Like a Rock

Dwayne 'The Rock' Johnson had a scary Labor Day weekend ... one minute playing with his new puppies, the next minute he's diving into his pool to save their lives. 

The Rock got 2 French Bulldog pups, Brutus and Hobbs. He let them loose in his backyard and they beelined it for the pool. Hobbs went into doggy style mode, but Brutus sunk like a rock.  

The action hero did what action heroes do ... jumped in and saved Brutus.  

At least he didn't have to make a Hobson's Choice.
