The Newton family live in their comfortable home, but there seems to something missing. This "hole" is filled by a small puppy, who walks into their home and their lives. Beethoven, as he is named, grows into a giant of a dog... a St Bernard. Doctor Varnick, the local vet has a secret and horrible sideline, which requires lots of dogs for experiments. Beethoven is on the bad doctor's list.

Beethoven is back -- and this time, he has a whole brood with him now that he's met his canine match, Missy, and fathered a family. The only problem is that Missy's owner, Regina, wants to sell the puppies and tear the clan apart. It's up to Beethoven and the Newton kids to save the day and keep everyone together.

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.

The family is pleasantly surprised and puzzled when Beethoven suddenly becomes obedient. Turns out it's a prince and the pauper scenario, with the real Beethoven now living with a pompous rich family.

When Sara takes Beethoven to spend summer vacation with wacky Uncle Freddie in an old mining town, the mischievous canine "digs up" the missing clue to a legendary hidden fortune of Rita and Moe Selig. Now everybody wants to be the dog's best friend as his discovery unleashes a frenzy of treasure hunting among the community's cast of kooky creatures. With help from Uncle Freddie and Garrett (a friend or maybe more), Sara and Beethoven try to help uncover a secret that has been in the crazy little town for years.

A Christmas elf accidentally takes off in Santa's sleigh, crash lands in a small town, and loses the magic toy bag. Beethoven must rescue the elf, recover the bag from greedy crooks, and return the sleigh to Santa in time to save Christmas.

Eddie, a struggling animal trainer and single dad suddenly finds himself the personal wrangler for a large and lovable St. Bernard whose fabulous movie "audition" catapults the dog to stardom. However, a trio of unscrupulous ne'er-do-wells have plans to kidnap the famous dog and hold him for ransom.

After everyone's favorite St. Bernard gets fired from a movie, Beethoven begins the long journey home with his trainer, Eddie. On their way, they become stranded in a small coastal town where the beloved canine befriends a young boy who is searching for buried treasure.
