The human world is as confusing as ever for our canine hero. He can't understand why Trixie is getting bigger and bigger, and Rex is getting more grumpy. Then Trixie comes home with another small human! And nobody seems keen on our hero getting very close to him. But he soon finds consolation with the rather attractive lady dog next door who goes through a rather similar transformation to Trixie! A rambunctious dog's eye view of the chaos a small baby brings to the house.
