Beethoven

Beethoven is the main character in the Beethoven film series. He is a St Bernard dog named after the German composer Ludwig van Beethoven. He weighs approximately 185 pounds. In the credits for the first film, he is credited as being played by a dog named Chris. However, in the second film's credits, he is credited simply as "Beethoven". As of Beethoven's 2nd, Beethoven has a girlfriend called Missy and is father to four puppies named Chubby, Dolly, Tchaikovsky and Mohawk (known simply as "Mo" in the film).

Backstory
At the beginning of the first film, Beethoven is a puppy who is stolen from a pet shop by two thieves named Harvey and Vernon, who work for the nefarious Dr Varnick, the film's main antagonist. With the help of a Jack Russell Terrier (later named Sparky by the Newtons), Beethoven manages to escape from Harvey and Vernon's van, but is then left to fend for himself after the terrier runs off, chased by Vernon. The next morning Beethoven wanders into the Newton household and his story unfolds from there.

Family and friends
Even after Beethoven grows into an adult dog, he is shown to still be friends with the Jack Russell Terrier who helped him escape from Vernon and Harvey as a puppy. He brings him food, as he is apparently living on the street and helping a hobo gather tin cans for unexplained reasons. When Vernon grabs the terrier by the scruff of his neck during the film's climax, Beethoven breaks out of his cage and chases Vernon, causing him to drop the terrier, showing that he is protective of his old friend.
