Beethoven’s 4th (2001)

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.
