This is the heroic moment a brave pet dog chased two bears away from a garden.

Footage shows the protective Golden Retriever barking at the beast intruders attempting to scale a metal gate at a property in Tibet, China.

One of the young bruins can be seen struggling to climb the railing, repeatedly slipping down during its attempts on May 26.

Moments later, it finally manages to clamber up the wall while its sibling waits nearby.

Meanwhile, the determined canine barks persistently, chasing the animals off without making physical contact.

The cubs eventually climb back down the concrete barrier and leave unscathed.

The homeowner said the bears likely wandered into the compound in search of food.

He added: 'When our dog saw them, he suddenly charged at the bears, protecting us.'

Golden Retrievers form strong bonds with their human families. While they are not aggressive by nature, their loyalty means they will instinctively step in if they sense a family member is in danger.
