Meet the Smiths: a happy family composed of two dogs, one cat, and two humans. But when the humans decide to adopt a dog named Trevor from the humane society, the other pets become sad, clingy, jealous, and afraid. Will Trevor get all the humans' time and attention? Who will play with the other pets, or snuggle them when they're lonely and blue? This comforting story about the arrival of a new family member reassures soon-to-be big brothers and sisters that sharing love means more love for everyone, not less love for them.
