Waiting for Doggo by Mark Mills
Dan’s live in girlfriend Clara abruptly leaves him without a trace after four years. She leaves her dog, named Doggo, that she rescued from the shelter. Dan is pretty distressed. Doggo is an extremely ugly dog. Dan tries to return the dog the shelter but changes his mind and takes him back home.
Dan is between jobs but his reputation is good and he gets a great offer. He will only accept if he is allowed to bring Doggo to work with him. The boss makes the unpopular decision to allow this as long as Doggo behaves.
Dan is happy in his new job. Doggo seems happy too.
This is a light, funny read with dastardly co-workers, a dog that seems smarter than he looks and enough of a story to satisfy.
