Jingle Barks: It's Dogs Barking 'Jingle Bells'. Hilariously. (VIDEO)

Yes, we know it's an advert. Yes, we know it's trying to sell us dog food.

But... we don't own a dog, so we're not likely to buy dog food. And if this YouTube video makes us go out and buy a dog so we can then feed it the dog food it's promoting, well... it's a bloody good advert.

But we're not going to go out and buy one. Because a dog's for life, not just for Christmas - right, kids?

Instead, we're going to watch this video over and over again, and marvel at just how daft and gullible (and well-trained) dogs are compared to cats. Enjoy!
