Rover Dangerfield is a 1991 American animated musical comedy film starring the voice talent of comedian Rodney Dangerfield, who also wrote the screenplay and story and co-produced the film. It revolves around the eponymous character, a canine facsimile of Dangerfield owned by a Las Vegas showgirl, who gets dumped off the Hoover Dam and finds himself living on a farm. Critical reception was unfavorable, although its animation received minor praise.

Rover Dangerfield is a Basset Hound living the life of luxury in Las Vegas with his owner Connie, a showgirl. One night, he sees Connie's duplicitous boyfriend Rocky negotiating with a pair of gangsters and accidentally disrupts it by dropping a bone into the meeting. Thinking Rocky is an undercover cop setting them up, the gangsters flee as their boss tells Rocky that he has blown his last chance as he claims that it was a "stupid dog" that intruded.

When Connie goes on tour for two weeks, she leaves Rover in the care of Rocky. In retaliation for ruining his deal, Rocky stuffs Rover in a bag, drives him to Hoover Dam and throws him into the water.

The bag is later pulled out of the water by two passing fishermen, who take Rover back to shore and place him in the back of their pickup truck. Rover regains consciousness, jumps out of the truck during a stop, and begins wandering down the road. He ends up in the countryside, and encounters a farmer named Cal and his son Danny. Danny convinces his father to take the dog in. Cal agrees on one condition: if he causes trouble, he will be sent to an animal shelter. Rover has difficulty adjusting to life on the farm but with the help of Daisy, a beautiful collie next door, and the other dogs on the farm, he succeeds in earning their trust. Rover spends Christmas with the family, and begins to fall in love with Daisy.

A pack of wolves attempt to kill a turkey on the farm. Rover saves the turkey, but the bird ends up dead from shock. Cal mistakenly believes Rover to be responsible for the turkey's death, and takes Rover into the woods to shoot him the next morning. The wolves appear and attack Cal, Rover fights off the wolves, and then rallies the other farm dogs to get the injured Cal home.

Rover's heroics make the papers; Connie discovers Rover's whereabouts and travels to the farm to pick him up and take him back to Las Vegas. Although initially satisfied to be reunited with Connie and his old friends, Rover soon begins to miss his life on the farm. Rocky comes into Connie's dressing room, and accidentally confesses to her what he did to Rover, causing Connie to break up with him. Infuriated, Rocky tries to retaliate, but Rover and friends chase him out of the casino, where he is beckoned into the gangsters' limo. When Rocky thanks them, the Big Boss quotes "This is a set up! Want to see Hoover Dam"? The limo then drives off as Rover waves goodbye.

Sometime later, Rover becomes despondent upon missing Daisy. Understanding that he misses his new life, Connie takes Rover back to the farm to stay, allowing Cal and Danny to keep him. Rover is reunited with Daisy, who leads him to the barn, revealing that he is now a father of six puppies: five of them resembling Rover and one resembling Daisy. The story ends with Rover teaching his kids how to play cards and happily chasing Daisy around the farmyard.
