This troper seems to fill this role in her group of friends (all of whom, interestingly, fill in the roles of FiveManBand and various anime stereotypes). One of the group even declared her "our unofficial TeamPet!"

This troper has officially embraced this role in her group of friends; she tends to get patted on the head like a dog quite frequently,

This troper draws a series of comics, usually unrelated. They usually consist of me, my friends (or family), my bear (appropriately named Teddy), and one or both of my pets. However, my group's TeamPet is actually not either of my cats, but the bear.
