Channel 4 must have come up with every bizarre documentary idea that's ever existed at this stage. Dogs on the Dole... like, what? The one-off special looks at the world of dog ownership on Britain's housing estates, revealing how, as their popularity has grown, so has the number of strays, especially in areas where money is tight. It will follow the work of canine charity Dogs Trust, which hosts open days across the UK, educating and encouraging owners to look after their pets properly, and offering free veterinary care with no questions asked.
