Ever walked past a parked car with an angry dog waiting inside it to scare the living daylights out of you?

Well this video reminds you why you shouldn't tease the beleaguered pooch - and that karma catches up with you.

The animation is from Birdbox Studios in London, and recently competed against the excellent Irish short (and viral sensation) 'The Missing Scarf' in the Encounters Film Festival in Bristol. 

If you haven't seen Eoin Duffy's award-winning animation already, check it out here:
