Robin and Scooby's relationship was very short-lived. In A Change of Heart, Robin asks Ted if she can get a dog. When Ted says no, Marshall advises Robin to get a boyfriend. She then meets Scooby in a park and introduces him to the gang. They notice that he behaves very much like a dog, which they point out to Robin. Later, the gang goes to Ted's apartment to eat "sandwiches". After a while, they wander the streets of New York until they find him peeing at a fire hydrant. In The Exploding Meatball Sub, Robin says that she has broken up with him.
