Four teams remain and this week the teams learn that they will each receive a new teammate - a-four-legged one. Once everyone selects their dog of choice, the guys are sent to a dog park, where they must try to get as many girls' phone numbers as possible. Meanwhile, the girls put their handy work to the test when they must build a home for their furry friend. Back at the house, a beauty realizes one of the guys is more than just a geek. Two teams go to the elimination room, but only one team goes home.

The final two teams are shocked when they learn of unexpected visitors who could jeopardize the competition. They prepare themselves for the big elimination by showing each other a side they've never seen before and one teammate makes a personal sacrifice that turns the competition upside down.
