Today's pets have cuddled, cooed and purred their way to elevated status in the family—and, in our alienated world, sustain deep emotional connections with the humans whose lives they share. From doggy day care to special toys and foods, the increasing anthropomorphism of the family pet is seen everywhere, especially in pet names. The most popular name for new puppies in 2004 was Max, according to PetData, an outfit that licenses animals throughout North America. For "girl" puppies, the favorites are Maggie and Molly. Quite a few conspicuously human-sounding names landed in the top 100 of New York City's dog database, too, including Bella, Sophie, Lily and Oliver.

"Animals are surrogates for children and appeal to our predisposition to nurture," says Sam Gosling, assistant professor of psychology at the University of Texas at Austin. "We've even selectively bred dogs to make them more like children—to have big eyes and small noses, to be attuned to our emotions and to give unconditional love."

The naming trend flows both ways: Amid the fervor for bestowing unique names on their tots, parents are choosing such common nouns, mythological characters and concepts as Destiny, Chance, Jupiter and Freedom—all of which could pass for pet monikers. "A lot of boundaries are getting crossed," says Pamela Redmond Satran, coauthor of Cool Names for Babies.
