Guru Guru Pon-chan volume 4

Ponta is a Labrador retriever puppy, the Koizumi family's pet. But when Grandpa Koizumi, an amateur inventor, creates the Guru Guru Bone, Ponta discovers she can use it to turn into a human girl! Ponta quickly meets and falls in love with Mirai Iwaki. And when he realises that she's actually a dog, Mirai learns to overcome it. Talk about an odd couple. In ways of the heart, it is certainly not an easy road for them. Plus Mirai's ex-girlfriend wants him back - by any means necessary. When Mirai and Ponta go to the beach together, the trip turns disastrous. Can Ponta make the romance work, or will she give up her life as a human forever?
