Mr Happy Face has a reason to smile, his crooked head and hairless body has received a crown

With a tuft of punk-style hair and a tongue sticking out, a dog named Mr Happy Face has been crowned the world’s ugliest pooch.

Organisers say the world-renowned event “celebrates the imperfections that make all dogs special and unique”

The 17-year-old pooch defeated nine competitors to take the top title

The champ was adopted as a rescue last year by a 41-year-old Arizona musician

She says Mr Happy face enjoys “sleeping, snoring, woofing in his sleep and making odd sounds when he is happy”.
