Beethoven's 4th

Beethoven’s family is surprised when their lovable, unruly dog suddenly starts behaving with perfect obedience. The change seems too good to be true, and soon the mystery points to a classic case of mistaken identity. While a well-mannered look-alike takes Beethoven’s place at home, the real Beethoven ends up living with a pompous wealthy family, creating confusion on both sides of the mix-up.
