The Black Dog Institute has launched a campaign to promote "Exercise Your Mood Week" from September 12 to 18.
Created by production company Jungleboys, the ad focuses on a man followed by the "black dog" of depression. As he hauls himself out of the house and embarks on an early morning jog, the dog reduces in size until it's a puppy.
The ad was based on research that showed regular exercise could be as effective at treating mild to moderate depression as medication.
