Quite possibly the most expressive dog you'll ever see, this 18-month-old Great Dane from Finland, could certainly never be accused of having a poker face!
Mutka, who lives in Finland with his human Krista Aalto, has been pulling funny faces ever since he was brought home at eight-weeks-old.
"He has always been an energetic and active dog; he's always happy and loves everyone and everything," she explains. "I am sure he must be one of the happiest and goofiest dogs in the world!"
Luckily for Mutka his human is a keen photographer, which means that his many faces have been well documented.
