Hero dog rescues 'drowning' owner

This dog doesn't hesitate in jumping into the water to help his owner who is pretending to get into difficulty.

When this dog sees his owner 'drowning', he wastes absolutely no time in jumping in and pulling him to safety.

And although his owner was in no real danger - he was just pretending to get into difficulty in the water - it's amazing to see the dog's protective instincts kick in.
