Move over, Grumpy Cat, there is a new grumpy pet in town! Meet the new internet sensation, Earl, the grumpy puppy. This five month old Puggle (Pug and Beagle mix) rocks a mean under bite that gives him his grumpy appearance, but according to his owner, Derek Bloomfield, he is as healthy (and as cute) as ever!

Earl's face went viral after Bloomfield posted a picture of his puppy on Reddit, which inspired him to create a Facebook and Instagram for Earl, called "Earl the Grumpy Puppy". Earl now has more than 18,000 followers.
