Bear is a small puppy. He has black fur, and bright, black eyes. Along with a little pointy snout, he has small ears that flop down.
After the Pullmans' first dog, Daisy, died, Nate Pullman came home with a white box. Inside was a puppy. When Isabel Pullman first sees the puppy, she decides that he looks like a little bear cub. Because of this, August suggested that they name the puppy "Bear." The rest of the Pullmans agreed that was a perfect name for the puppy, so he was named "Bear."
The next day, both Via and August stayed home from school so that they could play with Bear. The two of them took turns cuddling and playing tug-of-war with him. They had kept all of Daisy's old toys, so they brought them out to see which ones he'd like best.
