Pluto falls for Dinah the dachshund; so does Butch. She strings both along, until Pluto very sweetly gives her a bone. But Butch won't let her go, and keeps horning in, much to her annoyance.

Mickey goes into a souvenir shop out west and leaves Pluto with a buffalo bone to chew on. A small dog comes to take it away and runs into a ring of cactus with it; Pluto is too big to enter the same way, so he comes in from above and finds himself stuck inside until the small dog helps.

An owl teaches his class full of birds about melody. It's all around in nature. Only birds and man can sing; man "sings" even when he speaks. We see a quick survey of the stages of life, as captured by songs: the alphabet song for primary school, Here Comes the Bride, The Old Gray Mare, etc. Some inspirations for song are outlined in song: love, sailing, trains, the West, motherhood, etc., but "we never sing about brains." Finally, an example of how a simple melody can be expanded into a symphony: an elaborate version of the simple tune that opened the lesson

Minnie's learning first aid; she asks Pluto and Figaro for help. Pluto keeps throwing Figaro into buckets and otherwise getting him into trouble. Then, when Minnie has Pluto all trussed up in splints, Figaro taunts him.

As a ship's crew is on shore leave, seadog Pluto is left to stand watch. He sees a threatening shape, but it turns out to be a cache of bones. He grabs one and settles in contentedly. A rat sneaks on, and Pluto springs into action. The rat toys with him, until it finds the officer's mess. He bribes Pluto, until he hears an officer approaching. The rat hides, and Pluto gets thrown in the brig, while the rat sneaks off with his sandwich. But Pluto gets even.

Pluto has just finished moving his bones into a spiffy new doghouse when a turtle comes along and starts moving them out. While Pluto is dealing with the turtle, Butch takes up residence. Butch chases Pluto back to his grungy old doghouse, and now it's his turn to deal with the tenacious little turtle. The turtle wins, and he and Pluto become friends.

Pluto is guarding a flock of sheep in the West; a coyote is sneaking up on that flock. The coyote fakes a bad leg; Pluto chases it away, only to have it run back ahead of him and go after the sheep. Pluto gets back and finds the coyote chasing the lone black sheep of the flock, after trapping the rest. The chase ends with the coyote buried under a toppling spire of rock, which forms a coyote of rock on the top.

Mickey's on vacation at Camp Utopia. At first Pluto thinks it really is utopia: trees everywhere and a cat to chase. But the cabin rules are strict: no dogs indoors, and dogs must be muzzled and leashed. Mickey puts Pluto out to sleep, just out of reach of his food, and the cat comes down and taunts him. Pluto falls asleep and dreams of his "Plutopia" with a subservient cat begging Pluto to bite him and catering to his every need.

Pluto is patrolling a beach for the Coast Guard when a baby turtle hatches. The turtle keeps trying to sneak into the restricted zone to swim, and Pluto keeps trying to stop him. But when Pluto stumbles into some quicksand, he suddenly needs help from his foe.

When a pilot has to turn back due to a severe storm, he drops the mail at a remote outpost where it can be delivered by dogsled. The falling mail pouch lands on Pluto, and he sets out to deliver it.

Mickey Mouse sends Pluto to buy sausage at the butcher shop, but Butch schemes to steal it.
