Barking mad: The moment a fearless guard dog took on a polar bear more than twice its size… 

This is the moment a fearless guard dog took on a giant polar bear more than twice its size and won by scaring it away.

The huge bear approached the working dog, who is used to pull sleds through the snow in Churchill, Canada.

But rather than running away in fear, the determined dog stood its ground by baring its teeth and growling at the polar animal in a startled frenzy.

The curious bear seemed to approach the dog eager to make friends with the smaller animal.

But eventually the bear, who is considerably larger than the dog, was forced to make a retreat and trudge away into the distance from the fiery animal.

The incredible moment was captured on camera by photographer Alberto Panizza while he was visiting ɱaпitoba in Canada earlier this month.

The dog’s owner claims that he breeds the strongest dogs in the world and they someᴛι̇ɱes do throw themselves at the bears to scare them off

He revealed that the fearless dog was also chained up to stop it from escaping and went into survival mode when he saw the bear approaching.

The 39-year-old also said that the dog’s owner, a local breeder, claims his pets are the strongest in the world.

Mr Panizza, from Parma in 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 someᴛι̇ɱes throw themselves at the wild giants like this one did.’
