Output: Simpleton bachelor Fred Chaney Goldthwait inherits a bucktoothed horse named Don and one half of a stock brokerage firm from his dead mother. He discovers Don is a talking horse who can also speak the language of several other animals that belonged to his deceased father. His stepfather Walter Sawyer Coleman offers to buy out Chaneys share of the business for a paltry sum, but Chaney refuses. Instead Chaney returns Don to his talkinghorse family in the countryside and claims his place as partner at the firm. Chaney takes over an office and begins working as a broker, much to the chagrin of Sawyer. Don the horse overhears a stock tip and calls Chaney, presumably using his teeth to dial the phone. Chaney acts on the investment advice and becomes wealthy overnight. Chaney rents a fancy penthouse apartment and buys a sports car. Don the horse returns to the city and feigns illness. Chaney feels sorry for him and the two become roommates in the apartment. Dons father dies, but not before impressing upon Don the importance of producing an heir to the chosen line of talking horses. Conveniently, Don meets a beautiful white horse named Satin Doll at the stables soon after and develops a crush on the mare. Inconveniently, Satin Doll is a recent gift from Sawyer to his girlfriend. Chaneys successes continue, and Sawyer asks his secretary Allison Madsen to find out Cheneys secrets. She and Cheney go on an awkward date where a smitten Cheney naively reveals that Don is the source of his investing prowess. She assumes he is being facetious. Cheney insists Don can speak and returns to his apartment with her. Don refuses to talk. Don throws a wild party at the apartment with several species of animals in attendance; the apartment is damaged. Chaney becomes angry with Don and their relationship begins to sour. After eating delicious oats, Don suggests Chaney buy stock in the company. Despite being upset, Chaney takes Dons advice once again. The stock tip is a bust  the oats are contaminated and Don becomes ill. Sawyer learns of the oat companys impending collapse before Chaney and locks Chaney in the office bathroom before he can unload the doomed stock. Chaney is financially devastated. Allison learns of Sawyers actions and quits her job in protest. As she leaves the office, Don speaks to her for the first time. Realizing Chaney was telling the truth about Don, Allison transports the horse to reunite with Chaney. The three work together to get revenge on Sawyer. The plan is to enter Don in a horse race against Sawyer. Chaney goads an arrogant Sawyer into betting his horses against Don. Victory will win Cheney all of Sawyers prized equines, including Dons love interest Satin Doll. Unable to find an adequate jockey, Don having entered the race from the Pepperidge Farm Stables will be ridden by an inexperienced Chaney. While having second thoughts the night before the race, Don is visited by his father who has been reincarnated as a horse fly. Despite informing Don that it sucks being in his new form, Dons father delivers a rousing peptalk and Dons confidence is restored. Don is slow out of the gate but miraculously catches up to his competitors. He then fasttalks all but one of the other horses into abandoning the race through a series of ruses. The exhausted Don now trails a final challenger named Lord Kensington, the horse of Sawyer. Chaney struggles to motivate Don to overtake the leader. Finally, Chaneys promise of getting Dons teeth cosmetically capped spurs extra speed out of the horse and Don wins in a photofinish. The judges note that Don stuck his teeth out over the finish line to come in first. Sawyer is humiliated. As winners both Don and Chaney get the girl Satin Doll and Allison and the film finishes happily.
