Chou-Chou (シュシュ ''Shushu'') is a dog from Port Town who guards a pet shop, day and night, unmoving, as it belonged to his dead master. But, still being loyal to his master, a friend of mayor [[One Piece minor characters#Boodle|Boodle]], Chou-Chou kept guard over the pet shop.
When first meeting [[Monkey D. Luffy]], Chou-Chou swallowed the key to cage [[Monkey D. Luffy|Luffy]] was in at the time. Then [[One Piece minor characters#Mohji and Richie|Mohji and Richie]] appeared to search for [[Monkey D. Luffy|Luffy]], [[Roronoa Zoro|Zoro]], and [[Nami (One Piece)|Nami]]. When [[One Piece minor characters#Mohji and Richie|Richie]] spotted the pet shop they headed for it to get a quick snack. Chou-Chou fought against [[One Piece minor characters#Mohji and Richie|Richie]] to defend the shop, but got beaten. In the end, he could only watch his master's pet shop burn to the ground.
[[Monkey D. Luffy|Luffy]], out of his cage thanks to [[One Piece minor characters#Mohji and Richie|Richie]], saw how sad the dog was for the loss of his only treasure, and defeated [[One Piece minor characters#Mohji and Richie|Mohji and Richie]] as payback for Chou-Chou. After the battle, [[Monkey D. Luffy|Luffy]] presented Chou-Chou with a bag of dog food, the last one from his master's shop. Chou-Chou later helps the trio escape from the angry townspeople after [[Monkey D. Luffy|Luffy]] reveals that he was the one who knocked out the mayor, as well as a pirate. Chou-Chou is last spotted in Buggy's mini story in volume 5. Chou-Chou is shown biting [[One Piece minor characters#Mohji and Richie|Mohji]] on his rear end.
