In a new marriage, what happens when the husband brings his cute little terrier into a household where the wife already has her own biological dog? If the wife is Sara Swan Miller, she finds a way for her own dog, Natasha, to tell the world that she isn’t so happy about the new family member, whose name is Sylvia. But over time, Natasha gets to know Sylvia and her funny ways, and the two step-sisters find reasons to not only get along, but to like and even to love each other. It’s the kind of true-life story of a new marriage that not only happens with dogs, but with children as well, Everybody gets to figure out how to get along, or way better than that, just as Natasha and Sylvia do.
