How does a dog know its owner? Expert Advice

Your Pup’s Perception: Scent

Dogs are experts at telling people apart. A trained trailing dog can follow a complete stranger’s scent for miles, and he can tell that person’s scent apart from others. Dogs can even sniff out the differences between identical twins.

Bearing this in mind, it’s not surprising that your dog can also remember your scent when you aren’t around, according to a study published in a recent issue of Behavioral Processes. Scientists trained a group of dogs to sit while in an MRI machine and then individually recorded their brain activity as they reacted to the scents of people and dogs who weren’t present. These included a strange dog, a dog with whom they lived, a strange person, and a person with whom they lived — excluding their owners, since the owners had to act as handlers while the dogs were in the MRI.

The dogs exhibited greater brain activity for familiar people than for any other scent, even familiar dogs. Not only do dogs recognize and remember their humans’ scents, but they also get more excited about a whiff of “their” humans than about anything else.

We tend to think that dogs depend on their noses to find and recognize everything in their world, including people, but it turns out that they’re also very good at using their eyes. Dogs evolved to read human behavior and expressions as a result of their canine ancestors, who received warm places to sleep around human campfires by making people happy. To succeed at a survival strategy based on making another species happy, you need to develop a knack for reading expressions and body language — and that’s just what dogs have done.

A study led by Paolo Mongillo at the University of Padua in Italy in 2010 found that dogs can pick their owners out of a crowd by recognizing their faces. When dogs watched their owners and random strangers walk back and forth in a room, the dogs paid much more attention their owners than to the strangers. When both humans wore masks over their faces, however, the dogs had difficulty telling them apart and seemed to pay about the same amount of attention to both people.

How does a dog know its owner?

Dogs are comfortable showing love when they feel loved themselves. When you see affectionate behaviors coming from pups, it’s an indicator that they feel safe and loved by their owners and are willing to show that same love back.

Some behaviors are clear indicators of puppy love. Dr. Brian Hare is an expert in canine cognition and says that if your dog stares at you for no reason, your furry friend is really hugging you with their eyes. How cute is that?!

The classic tail wag is always an indicator of a happy pup, but another behavior that shows dogs know you love them is when they press or rub their bodies against your legs, or lay on your feet. This shows that your dog feels a sense of comfort and reassurance knowing you’re right beside them, and they certainly wouldn’t feel that if they didn’t also feel loved.

Herding their humans is another behavior that dogs sometimes exhibit to show family members are part of the ‘pack.’ When a dog is herding, they’re showing affection and care, and a desire to keep their family protected and in close proximity.

Next time you’re trying to get some privacy and Fido won’t leave you alone, remember it’s just because they love you.

How Your Dog Chooses His Favorite Person

Rodolphe Barrangou, Todd R. Klaenhammer Distinguished Professor in the Department of Food, Bioprocessing and Nutrition Sciences at North Carolina State University, has been inducted into the National Inventors Hall of Fame in recognition of his inventions, creativity, and spirit of innovation and entrepreneurship.

Barrangou becomes the seventh NC State faculty member to be elected into the hall. He is one of 16 new members elected this year. He will be formally inducted during a ceremony at the organization’s annual meeting in Washington, D.C., in October.

Barrangou focuses on understanding the genetic basis for health-promoting and fermentative properties of beneficial bacteria used in foods. A pioneer in the discovery of the adaptive bacterial immune system known as CRISPR, Barrangou has shown that CRISPR-Cas systems defend bacteria against unwanted invaders such as viruses called phages. Possible applications include genome editing, antibacterial and antimicrobial production, food safety, food fermentation, and plants, trees and livestock breeding.

While working at Danisco, a food ingredients company now owned by DuPont and recently acquired by IFF, Barrangou and colleagues – including fellow National Inventors Hall of Fame inductee Philippe Horvath – published a seminal CRISPR paper in the journal Science in 2007. That paper showed that CRISPR is an adaptive immune system that can acquire genetic snapshots of bacterial attacks by viruses. The related technology covering the use of CRISPR-Cas systems in dairy bacteria to enhance starter cultures’ resistance to viruses was patented in 2005 and has been widely commercialized for cheese and yogurt fermentation.

Barrangou has received numerous prestigious honors for his work on CRISPR-Cas systems. He was elected to the National Academy of Engineering in 2019 and was elected into the National Academy of Sciences (NAS) in 2018. He also received the NAS Prize in Food and Agriculture Sciences in 2018 and the NAS Award in Molecular Biology in 2017. He also received the 2016 Warren Alpert Foundation Prize and the 2016 Canada Gairdner International Prize, and was elected to the National Academy of Inventors in 2019.

Barrangou is the editor-in-chief of The CRISPR Journal, a peer-reviewed publication that brings together researchers and practitioners in a wide range of disciplines, including genetics and genomics, cell biology, immunology, infectious diseases, microbiology, molecular biology, neuroscience, plant biology, ethics and law, covering the many applications and implications of CRISPR.

He has authored or co-authored more than 200 peer-reviewed publications and is credited with more than 50 issued and pending patents.

Barrangou joined the NC State faculty in 2013. He received the 2014 NC State Alumni Association Outstanding Research Award and the 2015 NC State Faculty Scholars Award. He has been on the Thomson Reuters Highly Cited Researchers list since 2014. He is on the scientific advisory boards of a number of biotechnology companies and is a co-founder of Intellia Therapeutics, Locus Biosciences, TreeCo, Ancilia Biosciences and CRISPR Biotechnologies.

Barrangou earned his bachelor’s degree in biological sciences from the Rene Descartes University in Paris, France; a master’s degree in biological engineering from the University of Technology in Compiegne, France; a master’s degree in food science and a Ph.D. in functional genomics from NC State; and a master’s of business administration degree from the University of Wisconsin-Madison.

The National Inventors Hall of Fame was founded in 1973 in partnership with the United States Patent and Trademark Office to recognize individuals who have conceived, patented and advanced the world’s greatest technological achievements. It has evolved to become the nation’s leading nonprofit providing invention education programs and innovative competitions.
