It's not you, it's your four-legged friend.
If you just got a new puppy, don't be surprised when he starts dressing in all black, writing mediocre and over-the-top depressing poetry, and locking himself in his room to listen to Morrissey.
According to a study out of the University of Nottingham in England, DOGS go through a moody teenage phase just like we do.
And it hits when they're approximately eight months old.
So how do they show it? The researchers say, quote, "Most owners report that previously learned commands are forgotten, their dogs become very impulsive and easily distracted, and their behavior becomes a bit erratic."
On the bright side, it won't last . . . and they should mature out of it pretty quickly.
