Adorable St. Bernard puppy escapes from dognappers and wanders into the home of the Newtons, who, over dad's objections, adopt him. Beethoven grows into a huge, slobbering dog who sorely tries dad's patience. To make matters worse, two sets of villains also wreak havoc on the Newton's lives. Evil veterinarian Dr. Varnick plots to steal Beethoven for lab experiments, and yuppie couple Brad and Brie plot to take over the family business. Enjoyable cast, particularly Grodin as dad and Chris as Beethoven enable this movie to please more than the milk and cookies set. Followed by "Beethoven's 2nd."
