This is Pookie:
He started out life as a chew toy for Chloe, the pup:
But Chloe fell in love with little Pookie, and they became friends instead.
However, Chloe treats Pookie like a teddy bear toy, instead of an equal. Pookie resents this and periodically rebels and declares his independence.
Pookie dreams of one day running away to join the circus. (Shhh. Don’t tell Chloe). He often writes to his cousin, Buddy, who tours with a famous circus, about life under the big top.
But for now the circus is just a distant fantasy.
