No matter how cute they are, dogs who won't stop barking will eventually get on your nerves. Especially if you're a cat.
Chazz the puppy was a new addition to this couple's home, and they decided to film him while they were away at work to see how noisy he was. Sure enough, he started barking just after they left one morning, probably annoying the neighbors - until Greyscale the cat got fed up and shut it down.
I love how the cat gets in the startled puppy's face like a stern babysitter scolding a child, starts to walk away and then turns back and glares like "What did I just say?" when the puppy seems to think about barking some more.
