Einstein (portrayed by Freddie in the films and voiced by Danny Mann in the animated series) is Doc Brown's pet Catalan sheepdog. He later becomes one of the main characters in the animated series as the Brown family's dog.
In the first film, Einstein is placed in the time machine and successfully travels through time. Later, Doc has him placed in a suspended animation kennel when Marty travels to 2015. After Biff alters history, Marty and Doc leave him behind to correct their future.
In the animated series, Einstein becomes anthropomorphic and smarter, helping Doc with his inventions for traveling to the past and the future.
