Book excerpt: Based on the popular series of articles appearing fortnightly in the Telegraph, Ed Stourton muses on the meaning of life and all things canine as he walks his dog Kudu. Along the way he finds himself exploring much bigger subjects; war, bravery; office politics, current affairs, all given sudden levity and a new sanity when viewed through the prism of walking the dog. Funny, touching and surprisingly revealing, this is a sparkling source of amusement and comfort for dog walkers everywhere.
