A dog that grew up together.

I just saw it recently. It has a small, round head, as big as dad's fist. Two big triangular ears, its eyes are big and round, like two shiny black glass beads on its face. The nose and mouth are small, feel them with your hands, and they are wet. Brown short hair, soft and slippery to the touch. It has a short tail. It's thin, so it runs very nimbly.
