Monty was just like any other dog. A scruffy and irascible Maltese terrier, he enjoyed barking at pugs and sniffing at trees. But after yet another dramatic confrontation with the local Rottweiler, Anthony McGowan realises it's high time he and Monty had a chat about what makes him a good or a bad dog.

And they don't stop at ethics. Taking his cue from Monty's canine antics, McGowan leads us on an enlightening jaunt through the world of philosophy.

Will Kant convince Monty to stop stealing cheesecake? How long will they put up with Socrates poking holes in every argument? Do they have free will to pursue answers to these questions? Join the dutiful duo as they set out to uncover who - if anyone - has the right end of the ethical stick and can tell us how best to live one's life.

But there is also a shadow over their conversations. Monty is not well... And so towards the end the biggest questions raise their heads: is there a God? Does life have a meaning? By the time of their last walk together, Monty - and the reader - will find that they have not just solved a few philosophical puzzles, but absorbed much of the history of Western philosophy.
