Pet Myths: Are Dogs Really Man's Best Friend?

 

By Deidre Grieves
 

When it comes to the bond between dogs and humans, the term “man’s best friend” is frequently used to describe the inter-species relationship. But are dogs really man’s best friend? Is there validity in this commonly held belief?

 

According to researchers, dog trainers, and veterinarians, the answer is yes.

 

Dr. James Serpell, director of the Center for the Interaction of Animals and Society at the University of Pennsylvania School of Veterinary Medicine, says that the modern-day bond between humans and dogs dates back centuries and can be traced to the early interactions between nomadic human hunters and wolves.

 

“We don’t actually know why humans and wolves got together in the first place, but once that relationship was established, humans were selecting, very rapidly, for the most sociable wolves—the ones who responded to humans in this characteristically dog-like way,” says Serpell. “This was obviously something that humans valued from the get go.”

 

As dogs’ shifted into domesticated animals, they evolved to become part of the work force, helping humans with all kinds of tasks from herding to hunting. “We’ve sort of matured going through this world together,” says Dr. Katy Nelson, a veterinarian at the Belle Haven Animal Medical Centre in Washington, D.C., and a medical advisor for petMD. “If you think about how dogs were utilized, even 100 years ago, they were part of the work team. Whatever it was that you were doing for a living, your dog was out there helping you do it.”

 

Today, dogs are an integral part of family life, and studies show the strength of the animal-human bond. A 2015 study published in the journal “Science,” demonstrates that there is a real emotional connection that happens when dogs and people look at each other. Data from the study reveals that oxytocin levels rose in both humans and dogs after they looked into each other’s eyes during a 30-minute period. Oxytocin is often referred to as “the love hormone” because it’s produced in the body when humans have close contact with the people they love. The hormone is also associated with maternal bonding and rises when mothers interact with newborn babies. Other studies show that dogs can recognize human facial expressions and make decisions based on those expressions, showing a high level of emotional intelligence in pet dogs.

 

“They actually read our facial expressions,” says Victoria Schade, a certified dog trainer, speaker, and author. “That might seem hard to believe, but there’s a really cool test you can do. Look at your dog, don’t say anything, and just smile. I guarantee you’re going to get a tail wag back.”

 

Dr. Carlo Siracusa, a clinical assistant professor of behavior medicine at the University of Pennsylvania School of Veterinary Medicine, explains that how humans interact with dogs has a big impact on a dog’s overall demeanor. “Dogs are much more likely to listen to you when you have a happy face,” he says. “And if we’re talking about friendship—that’s how it works. If I’m friends with someone and I know when [that person] is really, really, really upset, I tend to be very cautious. It’s exactly the same thing for dogs.”

 

While dogs may be hyper aware of how their human counterparts are feeling, Schade says that some pet owners don’t always give their dogs the same amount of consideration and attention. “Dogs are constantly scanning—[wondering] whether we’re happy or sad,” she says. “We should also look at our dogs and say, ‘Do you feel okay?’ ‘Are you comfortable in this situation?’”

 

Siracusa agrees. “Dogs are man’s best friend,” he says. “But humans should make more of an effort to show this friendship to dogs.”

 

Despite human flaws such as texting at the dog park or cutting playtime short to binge watch Netflix, dogs remain loyal and loving companions. “I have to admit, it’s nice to have an individual there that seems to consider me to be the most important person in the world,” says Serpell.
