"Kako's Puppy!" is an episode of Oobi from the first season.
Oobi learns that even though puppies are cute and cuddly, they are also a big responsibility. With Grampu's guidance, Oobi learns to feed, walk, and bathe the puppy. He finally gets to play with the puppy, too! — ABC Television
Oobi and Grampu are in the backyard when Kako walks up to them with his pet puppy. Oobi takes an instant liking to the dog and plays with it. Kako asks Oobi to watch his puppy while he is away for the day. Kako walks off, leaving Oobi with the assumption that both he and Grampu are going to be taking care of the puppy together. Grampu tell him that Oobi is in charge of the puppy, not both of them. He tell him that he has to walk him, feed him, and wash him before he can play.
Grampu begins by telling him to walk the puppy by setting up its leash. Oobi does this, albeit after refocusing his attention on walking the dog, as he was playing with it instead of working. After walking the puppy, Oobi must feed the dog by preparing a bowl of food for it. Grampu brings out a bag of dog food, and Oobi pours out some food for the puppy to eat. This makes Oobi hungry as well, so he feeds himself a saltine cracker.
After their snack, they then go wash the puppy in a small tub. He tells him to add shampoo, wash the puppy, and then rinse it off. Oobi adds the shampoo, but then forgets what to do next, so he asks the viewers for help. He then washes the puppy by lathering the shampoo into his fur, and then they rinse him off. The puppy jumps out of the tub, leaving Oobi with the assumption he is done, but Grampu says he isn't. He then picks up the hose and starts chasing Oobi around with it, saying HE needs a rinse.
Grampu tells Oobi that he is proud of him, and that he can now play with the puppy. He then notices that the puppy's tail is wagging, so he and the viewers imitate it until Kako returns. Kako calls Oobi an official "puppy-sitter". Later, the boys notice that the dog is sitting on a log, so they play a rhyme game with words that end in "-og". After the game, an interview segment plays. It involves Oobi asking the viewers if their pets can do any tricks. The episode ends afterwards.
