Uplifting true tales of remarkable seniors.<br/><br/>Puppies are wonderful, but there is something truly special about an old dog. It's the grey muzzle and salt-and-pepper eyebrows; the face that says 'been there, sniffed that.' It's the plodding gait; the long naps in the sunshine; the undiminished wonderment at the beauty of the world. And more than anything, of course, it's the lifetime of love, laughter and licks. Most dog lovers wish their four-legged friends could live forever, and yet senior canines are surrendered to shelters and rescue groups in heartbreakingly high numbers. For some people, it seems ageing is an inconvenience rather than an achievement to be celebrated. But every day, all over the world, elderly dogs are doing incredible things. From saving lives and breaking records to leading online movements and surviving against the odds, stately seniors are wringing every ounce of joy and adventure from their lives. In Extraordinary Old Dogs, meet the geriatric tail-waggers proving there's plenty of life in the old dog yet.
