Ellie is a show dog that Brian meets and falls in love with during a trip to the vets in "Boy (Dog) Meets Girl (Dog)".
When a depressed Brian eats a box of Valentines chocolates and is poisoned, Brian meets Ellie at the Quahog Veterinary Clinic. Smitten with her, they go on dates but his physical impulses are rejected as he finds that Ellie is under contract to breed with the winner of a dog show. Enlisting Stewie's help, he enters the competition and wins, but is unable to perform when he finds out that it will be in front of the entire audience so the honor is given to the runner-up.
Ellie is voiced by Amanda Seyfried.
