Puppies!Earlier this week Forbes.com ran a story about pet culture in the U.S. in the 21st century, which has transformed our four-legged pets into our children.

About the trend:

America’s cultural pendulum has swung toward pets. According to the American Pet Products Association (APPA), a trade group, 62% of U.S. households own a pet, and most are willing to spend vast amounts of time and money to keep Sparky and Fluffy happy. The pet industry has tripled in the past 15 years. The APPA estimates pet spending will reach $45.4 billion this year, an increase of $2 billion since 2008–despite the crippling recession.

In the last few years, they’ve exploded into popular culture, too. As Paris Hilton and Jessica Simpson are splashed across the celebrity glossies with their furry friends, the broader media followed suit. People.com offers the offshoot People Pets.com, AOL draws audiences with its new site Paw Nation, and icanhascheezburger.com gets hundreds of submissions daily of user-generated lol cats (laugh-out-loud funny photos of cats). Bo, America’s “First Dog,” is still making headlines.

And sociological commentary…

“People are fascinated by pets. We act and spend on them as if they were our children,” says NYU sociology professor Colin Jerolmack, who studies animals in society. “We’ve civilized them to the point that they are no longer a part of wild nature.” It wasn’t always so. Just over a century ago in the 1800s it was very rare to have a pet, Jerolmack says. They were luxury items and status symbols of the bourgeoisie, showcasing that a family had the means and resources to own a pet. Animals then were purely functional; dogs were often used to hunt, and cats used to scare off mice. As society developed and technology advanced, the utilitarian use of pets waned.

And from another sociologist…

Author of Understanding Dogs, sociologist Clinton Sanders, says pet obsession has been rapidly growing during the past 20 years. “The danger is that we don’t let animals be animals anymore,” he says. “It does them a disservice and results in some ignorant kinds of treatment.

“Dogs,” he says, “would be perfectly content eating the same food every day for the rest of their lives. It tastes good, fills them up and never disappoints. A dog’s owner, on the other hand, might say, ‘I would never want the same meal again and again, how boring.’ Then she goes to the store and buys her pup a variety of options, which in turn disrupts the dog’s digestive tract.” But, Sanders insists,”Dogs aren’t like us.”

Similarly, interpreting their behavior as if they were human can lead to false assumptions. Says Sanders, “People might believe the dog peed on their bed because she was angry that they were gone, but what if the dog has a urinary tract infection? It’s an inappropriate way of understanding their behavior.”

But why are we so crazy about our pets? NYU sociologist Colin Jerolmack, quoted above, has an answer…

Why have they become so important to us? NYU’s Jerolmack speculates that it may be due to people’s decreasing connection to each other. In an era of online social networks, long work hours and distances between families, we have far fewer strong social ties and many more weak ties, he says. “We’re spending a lot more time alone or with our immediate family. The companionship of pets has become much more valuable today.”

Furthermore, relationships with pets are much less emotionally messy. They love you no matter what you look like or if your breath stinks. And they show affection consistently. Pets have become a relatively easy and loveable replacement of children or a strong community, which, Jerolmack warns, may lead to an impending culture clash.

“In the city, we’re already seeing debates over park space going to kids or dogs,” says Jerolmack. “There will be more people demanding social recognition of pets, wanting to bring their pets everywhere. And with an industry relying on them, I don’t see us going backwards.”
