Wilfred and Adam enter a competition with each other to decide who is the happiest.

Sarah takes Adam home to Nambour to meet her family and get nude while Wilfred rekindles hostilities with his old man.

Arthur continues to bully Wilfred until they partake in a particularly vicious game of force 'em backs from which only one dog will emerge alive.

Sarah goes away for her last piece of pre-wedding freedom and Wilfred takes the opportunity to bully Adam and eat-up a storm.

A holiday to the snow takes a bad turn when Wilfred, Adam and Sarah meet sexed-up Swedish couple Lars, Hilda and their dog Annika. Wilfred suffers performance anxiety.

Wilfred is romancing, Caddy, one of the local dogs, while Adam and Sarah receive a visit from Adam's extraordinarily good looking and clever brother, Spencer, with the expected consequences.

Sarah's annoyed that Adam still doesn't have a job. Wilfred sees a dog that looks like him on a television commercial and decides he wants to be a dog star, asking Adam to manage him.

Adam needs to find some money for the rings as Sarah is adamant - no rings, no wedding. Wilfred reckons he'll be able to earn the money by taking part in an illegal dogfight on the mean streets of Richmond.
