'As with dogs, so with gods - by and large, you should blame the owners.'A particular trait, common to all human civilisations, is the worship of non-human entities with followings of devotees who claim that their reverence can transport them to transcendental heights of complete and unfettered love.Do we mean God? No - we mean Dog. Dogs and other pets we've been keeping and loving since we began walking on two feet. But why do we love God - and pets - so much when their capriciousness sometimes suggests that they don't love us back?In this wise, witty and highly topical book, celebrated cartoonist and novelist Martin Rowson argues that rationally, the whole enterprise of religion is a monumental and faintly ridiculous waste of time and money. But then again, so is pet-keeping.
