Courageous bulldogs charge at black bear

You may think you're brave, but you're not this brave.

Two bulldogs have been filmed barking at and chasing away a massive bear that wandered onto their family farm in the US state of New Hampshire.

The two dogs are heard growling and barking on the veranda as the inquisitive black bear sniffs at the seeds in a birdfeeder dangling from a tree.

But this intrusion is not welcomed by the pets, who race up to the bear as it stands on its hind legs, confronting it from mere centimetres away.

Despite their courage, the size difference between the animals is absolutely overwhelming.
