Beethoven's 4th

A father checks in with his two children before school. The family includes a girl, boy, artist father, and campaigning mother, and a St. Bernard (dog) dog named Beethoven (film), who they are keeping for a relative family. The children love Beethoven, but their parents do not, and want to get rid of him. So the children begin taking the dog to Obedience Training led by a former army sergeant. Brennan falls in love with a girl (Hayley), while Beethoven literally destroys the obstacle course in one day. To top it all off Beethoven hits the army sergeant in the groin with a leash causing him to kneel over in pain.
