Beethoven’s 3rd (2000)

Everyone’s favorite St. Bernard returns in this family film about man’s best friend. Richard Newton, his wife Beth and kids Brennan and Sara shove off in their camper for a road trip. Along the way, they gain a new passenger: slobbery Beethoven. The Newtons plan to return Beethoven to his owner — but not before he turns hero when a pair of thieves enter the picture.
