Grin and bear it: Brave dog takes on polar bear…and wins
This is the moment a brave guard dog took on a giant polar bear – and WON.

The dog barks ferociously at the polar bear
The determined mutt fiercely stood tall when the giant bear approached, forcing it to retreat and trudge into the distance.

Although the polar bear seem unfazed, the dog but a brave show, barking and showing its teeth
Keen photographer Alberto Panizza, 39, captured the incredible moment while visiting Churchill in Manitoba, Canada, earlier this month.

Sensing that the bear was up to no good, the dog warns the bear by barking loudly
The snapper revealed the fiery pooch was approached by the bear and reacted in a startling frenzy as soon as it sensed danger.

Although the dog was chained to a post, it still attempted to take on the huge bear
The dog – chained up to stop it escaping – was owned by a local breeder who claims his dogs, used to pull sleds, are the strongest in the world.
Alberto, from Parma, Italy, said: “The dogs live not far from a town where polar bears often pass through.
“This one seemed to be curious and even though much bigger it was eager to make acquaintances with the dogs.
“Even if they are trained to fight bears, the dogs usually seem afraid.
“But either due to their survival instinct, or pure madness, they sometimes throw themselves at the wild giants like this one did.”
