''Guru Guru Pon Chan'' is a manga series created by Satomi Ikezawa, the creator of ''Manga/{{Othello}}''.

It tells about a Labrador Retriever pup named Ponta, the Koizumi's family pet and trouble maker. One day, Grandpa Koizumi creates the Guru Guru Bone in order to make animals speak in English. When Ponta eats it, she turns into a little human girl. Ponta runs outside and meets Mirai Iwaki, the most popular boy in his school when he saves her from almost being hit by a car, falling in love with him at first sight before puking up the Guru Guru Bone and running away. Realising that she has fallen for Mirai, she resolves to become human so they can be together. By the time she recovers the Bone (which Mirai kept) she's aged enough that when she kisses it she takes the form of a cute teenage girl. Mirai likes her even after finding out she's a dog, but questions whether a relationship between human and canine can ever work, or whether he's doomed to become known as "the pervert who does it with dogs". And so their bumpy relationship begins...

The series ran for 9 volumes from 1998 to 2000, which were released in English by Creator/DelReyManga. A 4 volume spin-off sequel called ''Guru Guru Pon-chan Okawari'' ("Second Helping") was released several years later, which focused on a girl with a male chihuahua who becomes human instead of the original characters.

!!Tropes included:

* AlphaBitch: Rumi. She rapidly becomes irrelevant though.
* BackFromTheDead: [[spoiler:Well, Ponta wasn't ''actually'' dead, but considering she slept through her own funeral and had to be ''rescued from the crematorium oven'' it's hardly any different.]]
* {{Cloudcuckoolander}}: Ponta comes across like this sometimes due to being, well, a dog. [[spoiler:Aoka is also nuttier than a fruitcake.]]
* DemotedToExtra: Soichiro and Mama are quickly reduced to having practically no role in the series. On the other hand, Papa never really made it ''beyond'' extra.
* EroticEating: The first time Ponta goes into heat, she eats a pear so delightfully that she hospitalises half the boys in school [[{{Nosebleed}} due to catastrophic blood loss.]] The second time she starts mouthing a Matsutake mushroom in an incredibly suggestive manner.
* {{Fanservice}}: Ponta is also a real InnocentFanserviceGirl.
* GirlishPigtails: Ponta sports these in her human form.
* IncrediblyLamePun: The first time Ojii-chan has Ponta transform intentionally, she repeatedly spins around for a brief TransformationSequence. "Guru guru" is "spin" in Japanese.
* InterspeciesRomance: Ponta and Mirai.
* MediumAwareness: Happens quite often.
-->'''Soichiro:''' This can't be happening! [[LampshadeHanging It's not like this is a manga or something!]]
-->'''Ojii-chan:''' ...but it ''is'' a manga.
* MoodWhiplash: Sometimes hits ''really'' hard, especially at the end of the [[spoiler:Ponta's pregnancy]] arc. The arc to that point had been about [[spoiler:Ponta apparently being raped by Gang and becoming pregnant, Mirai agonizing over whether he'd be able to accept her after that and his eventual decision to be a father to her child no matter ''what'' it was like]] only to end with [[spoiler:a giant constipation joke.]]
* NakedOnArrival: If Ponta is not wearing clothes as a dog and then turns human, she'll be completely nude.
* {{Squick}}: Even if the basic concept doesn't bother you, some of the jokes are rather off-putting. [[spoiler:Ponta's "pregnancy" really being a simply ''immense'' case of constipation is just... ugh.]]
* RidiculouslyCuteCritter: Ponta as a puppy, usually in flashbacks.
* StalkerWithACrush: [[spoiler:Aoka and, to an extent, Gang.]]
* TeenPregnancy: [[spoiler: Turns out Ponta's not pregnant just... really, ''really'' constipated.]]
* TransformationTrinket: Guru Guru Bone.
* WhatMeasureIsAHumanoid
* {{Yandere}}: [[spoiler:Aoka]] initially seems to be like this, but is eventually revealed to be just a complete {{Cloudcuckoolander}}. Still quite probably ''insane'' (she thinks the fairies talk to her) but not malevolent.
