Dogs.

Although Winston- the black pug- is less than half the size of Phoebe, he is in charge. So much so that as soon as she lies down he sits on top of her and asserts his dominance.  They are inseparable.  He even cleans her eyes and ears so I suppose it is a symbiotic relationship.
Extra is my granddaughter surrounded by mayhem. The room can go from tidy to chaos in a matter of moments.
