Pochi is one of the main characters of Tama and Friends. He is a pure white dog with a red collar who lives in a doghouse at a local tofu shop run by his owner, Yamada-san. His birthday is October 2, and in the English-language version of the early anime he is also known as Doozle.

Pochi is Tama's best friend, and the two are almost always together. He is gentle, kind, and caring, but he also has a timid side and is easily frightened by many things. He worries about the friends he cares for and prefers a calm, quiet life, yet he frequently finds himself caught up in unexpected adventures alongside Tama. Although he is naturally nervous, he wants to be seen as strong and tough, and he once went through a brief period of rebellion in an attempt to present a braver image.

His primary motivation is his close friendship with Tama and his place among the neighborhood animals. Even when fear gets the better of him, he follows his friends into their explorations and remains a loyal presence in the group. Within the story, he functions as Tama's closest companion and one of the central figures in the everyday episodes, balancing the more curious and carefree cat with his cautious and gentle nature.

The most important relationship in his life is his friendship with Tama, a bond built on mutual trust and shared experiences. He also has a strong connection to his owner, Yamada-san, and the tofu shop that serves as his home, and he interacts regularly with the other animals of the neighborhood.

Over the course of the series, Pochi's character is defined by his ongoing efforts to manage his fearfulness. He remains gentle and easily scared, but his loyalty and his willingness to stand by his friends reveal a dependable side beneath his anxious exterior.

A notable ability associated with Pochi is his famous talent for telling the difference between soft and firm tofu without touching it, a skill linked to his life at the tofu shop.
