A Fierce Glitch Upon Reality, Book 1 of the Good Boy Ascension series

When the System glitches and enthrones dogs as Earth's ruling species, mild-mannered accountant Ben and his spoiled corgi, Sir Barksalot, are thrust into a tutorial designed for hounds. To succeed, Ben and Barksalot must master the Language of Treats and Loyalty Skills, while Barksalot leverages his new genius intellect to exploit game mechanics for power, infinite belly rubs and premium kibble. Humanity must confront its role in a new world order where a dog's bark is is just as, if not more, important than anything a human has to say. And it tuns out that the System glitch was not an accident. Earth has been under surveillance and is a viral sensation across the galaxy.
