Tuna isn’t just an ordinary dog.

He’s an adorable Chihuahua-Dachsund (Chiweenie for short) who became an internet hit a few years ago, thanks to his pronounced overbite.

With 1.3 million followers on Instagram and his very own line of merchandise, Tuna has taken his world domination a step further with a pictorial autobiography – documenting all his best Instagram moments into a book.

“I was approached last Fall by an American publisher to write a book and they gave me complete creative freedom,” says Courtney Dasher, who adopted him.

“I wanted to create a story that was ‘a day in the life of Tuna’ to give his audience more of an inside look into his life.”

And here’s a glimpse of what to expect…
