In the anime, some time after Pakkun and the other ninken made a contract with Kakashi, they aided him search for the fleeing Orochimaru. Pakkun was with them when Kakashi and the Root ANBU Kinoe pursued him into the residence of the Iburi clan to save the only survivor, Yukimi.
Despite his cute appearance, his voice is deep and gruff. In the anime, he revealed that he used Floral Green shampoo (English TV "Minty Rain Forest Mist Shampoo with extra bodywash"), which is also used by Sakura, who was comically traumatised at the thought of using the same shampoo as a dog. In Japanese, Pakkun uses "washi" (ワシ) when referring to himself, which is generally used by older men. Despite his lazy demeanour, Pakkun is shown to be fiercely proud and determined ninken. When offered by Sai to deliver a message with one of his ink creatures, Pakkun insisted that he deliver it, not wanting to look inferior. He is very loyal to his allies and at times curses his inability to get more directly involved in battle.
Pakkun is a small, pug-like dog with brown fur and a dark brown snout and ears. He has pink-coloured paws and wears the standard outfit of Kakashi's ninken which consists of a blue vest with the heno-heno-moheji seal and a Konoha forehead protector, but his is worn on top of his head in a similar style to Sakura Haruno. He also wears a bandage on his right front leg.
Pakkun is revealed to not be a battle-type ninken, which Sakura claimed to know by looking at his small appearance. Despite this and his small size, Pakkun has shown to be a very useful summon. He has been repeatedly shown to have an incredibly sharp sense of smell, even by canine standards. He can regularly determine what type of scent he is picking up, how far away it is, and how dangerous the person is. In the anime, he was shown even able to detect a target's scent that has been masked. Also, he has been shown to have tremendous speed from how effectively he can keep up with full-grown human ninja, even challenging others to keep up with him. He also has a great amount of strength as he was able to drag Shikamaru with him when he refused to help find Sasuke. He has also displayed exceptional teamwork with the rest of his pack developing and effectively using several offensive and defensive formations in battle which make use of the manoeuvreability and powerful limbs. He has also displayed the ability to make clones of himself from his hair.

- According to the anime, Pakkun was able to say Kakashi's name at four months of age.
- During the invasion of Konoha, Shikamaru refused to help in finding Sasuke. Pakkun told him that, if he completed this mission, he would let him touch the pads on his feet, which he claimed were really soft and supple. This is a reference to modern Japanese culture, in which a dog's paw is considered its cutest aspect; the idea of an animal's paw being "cute", however, applies mainly to puppies and kittens, because at birth their pads are pink, and, as dogs grow older, they turn into a dirty black. However, Pakkun's paw pads are still pink even though he's a full grown dog.
- The heno-heno-moheji seal on the back of Pakkun's jacket is a face that is drawn on scarecrows in Japan by children. The scarecrows are also called "Kakashi", which is a name of Pakkun's summoner.
- In 2005, a Pakkun-shaped controller case was given away as the bonus to those who pre-ordered Naruto: Gekitō Ninja Taisen! 4 in Japan.
- Pakkun was shown in episode 20 on Naruto's key chain and appears again in episode 176. He also appears as a souvenir in episode 110.
- Due to his short stature, whenever he is summoned with the other ninken, he appears on top of Bull's head, as opposed to the others, who always appear on the ground.
- Pakkun is playable in Naruto: Path of the Ninja 2 as a summoning (optionally) if the player put a Ninja Tag on the characters such as the Anbu.
- His only technique in Path of the Ninja 2 is Bite.
- The face on the back of Pakkun's jacket is also the face of the narrator in the spin-off anime, NarutoSD: Rock Lee and his Ninja Pals.
- (To Shikamaru) "Look, if you succeed in this mission, I'll even let you touch my paw."
- (To Naruto) "Stupidity is a powerful thing."
