Beethoven’s 4th

Richard Newton Judge Reinhold checks in with his two children, Sara Newton and Brennan Newton before the school day begins, while the rest of the family remains occupied with Beethoven, the beloved St. Bernard that the kids are caring for on behalf of relatives. The parents, Reginald and Martha Sedgewick, would rather be rid of the dog, but the children adore him and find joy in his playful, faithful presence. The morning routine is a mix of warmth and tension as the Newtons balance love for their pet with the parents’ practical concerns about keeping him in the house. The children’ s attachment to Beethoven is clear, even as the adults weigh the pros and cons of a pet that seems to complicate their day-to-day lives.

The plot thickens when the family enrolls Beethoven in an obedience training program led by a former army sergeant, Art LaFleur. Meanwhile, Brennan forms a budding crush on a girl named Hayley, adding a lighter, hopeful note to the busy routine. In a surprising twist, Beethoven’s natural talent emerges almost instantly: in just one day, the dog bulldozes through the obstacle course, and in a rush of chaotic humor, even knocks the army sergeant to his knees with a wagging leash. The scene blends mischief with affection as the dog’s energy reveals itself in unexpected—and sometimes inconvenient—ways. The family dynamic becomes more complicated when the same dog’s uncanny intelligence and mischief begin to blur the lines between their two households.

Across town, the pampered yet identical-looking dog Michelangelo belongs to the wealthy Sedgewick family: Reginald Sedgewick and Martha Sedgewick own a perfectly trained, impeccably behaved canine that seems to live in a sparkling, controlled world. Their daughter Madison Sedgewick is friends with the real Beethoven’s look-alike, creating a recurring mix-up between the two dogs. A crucial turn comes when the real Michelangelo is mistaken for Beethoven and is grabbed by their butler, Johnnie Simmons, pulling the family into a web of mistaken identity and social contrast. The Sedgewicks’ home feels refined and orderly, yet the dog’s presence exposes cracks in their carefully curated image.

Dinner routines reveal further quirks. Michelangelo wipes his feet on the welcome mat and neatly folds napkins with his teeth at the table, a curious display that signals a shift in behavior that does not go unnoticed by the family. The Sedgewicks attribute these subtle changes to the dog’s uncanny habits, while the real Beethoven’s more endearing traits—like his instinct to comfort Madison when she dreams badly—also surface in quiet moments. The obedience class becomes a stage for revelation when Michelangelo astonishingly finishes the new obstacle course, prompting astonished reactions from the sergeant and the attendees. It is a moment that underscores how appearances can be deceptive and how differently a dog can adapt to training depending on its surroundings.

A key conflict erupts at a tense dinner party when a man named Nigel Bigalow attempts to dognap Beethoven. The situation triggers a cascade of observations from a therapist, who points out that the “symptoms” observed in Michelangelo may reflect Martha’s self-centered tendencies rather than a mutual bond with her family. The therapist’s insights push Richard to mirror Beethoven’s behavior in a misguided bid to provoke mischief, leading him to drink toilet water and chase the mailman, among other antics. In a reversal of roles, Michelangelo begins to imitate Beethoven’s authentic, unfiltered energy, further muddying the boundaries between the two dogs and their owners.

The heart of the movie lies in the evolving bond between humans and their canine companions. The two dogs become focal points for family love, jealousy, obligation, and the desire for belonging. The Sedgewicks start spending time with Beethoven—playing fetch and swimming together—while the Newtons find themselves drawn into a broader, more chaotic world of dog-related adventures. The tension crescendos when Nigel kidnaps Beethoven and holds him for ransom, forcing a dramatic, clandestine escape. Beethoven manages to switch places with Michelangelo at the obedience graduation, a swap that goes undetected by all but the most observant eyes.

The aftermath resolves with two critical arrests: Simmons and Nigel are taken into custody by FBI agents, and the real Beethoven is discovered by the Newtons, who celebrate the dog’s graduation and confirm the joyful bond they share with him. Yet the two families—Sedgewicks and Newtons—meet at a fork in the road, a symbolic moment that leaves them with a choice and a lingering sense of mystery: they never learn the full truth about the swap between Beethoven and Michelangelo, but their paths have undeniably intertwined through laughter, loyalty, and the unmistakable presence of a dog who brings people together in unexpected ways.
