That New Animal by Emily Jenkins

Two dogs have to adapt to the introduction of a new baby in the household. At first suspicious and unhappy, they surprise themselves when grandpa comes to visit.

An excellent book that could be used to explain the new baby concept to an older sibling or the importance of pet's roles in the household. The illustrations are amusing and colorful.
