Beethoven's 3rd 2000 ( 5.178)

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.
