Rosie, a dog, was born to be a mom. Even though she was spayed and couldn't have puppies of her own, her humans took care of that for her. Rosie arrived at a house with two cats, Juniper and Beech. Surprisingly, the dogs and cats got along well and became friends. But Rosie wanted someone to play with, and that changed when her human gave birth to a little boy named Tyler. Rosie became attached to Tyler, sleeping with him and protecting him as if he was her own. Rosie's paws are often seen draped across Tyler, showing how much she loves him. Juniper and Beech aren't as snuggly, but everyone is happy in the new home. Rosie's story makes the narrator want a tiny human of their own. They wonder if they can convince their humans to make that happen.
