A hiker attacked by a brown bear in a forest in Slovakia has been rescued by his dog after it bit the bear on the backside.

The 42-year-old man, who was not named, was hiking in the Lower Tatra area, east of Bratislava, accompanied by his dog when the fully-grown bear burst from the bushes and bit him.

But the bear was forced to let the man go when the dog sank its teeth into the animal's rump.
