As dog owners, we readily admit that we love our dogs. Why else do we get out of a warm bed and take them outside in freezing temperatures early in the morning? Why do we leave a great restaurant before dessert and head home to feed them? Why do we immediately forgive them after they chew on our favorite slippers? To say that dogs are "man's best friend" is an understatement for many of us. However, the lingering question remains… Do our dogs love us?
What does the research say?
An innovative team of scientists from Emory University in Atlanta, Georgia, took a clinical approach in investigating the emotional state of dogs. Using MRI (magnetic resonance imaging), researchers scanned their brains and exposed them to certain odors. Changes in brain function provided data on the emotional state of the dogs.
Why smells? Dogs navigate the world with their sense of smell. In fact, unlike humans, dogs depend on their sense of smell more than their sight to interpret their surroundings. The way dogs process and react to odors reflects their feelings. The experiment used odors to stimulate the dog's brain. Using MRI, the researchers measured the dogs' neural responses when they were exposed to the odors of familiar and unfamiliar people and dogs.

The experiment revealed that when the dog smelled the familiar aroma of its owner, the "reward center" in the brain (caudate nucleus) was activated. The caudate nucleus contains many dopamine receptors, and in human brains, as well as in dog brains, it lights up when exposed to pleasurable experiences. For example, the smell of your favorite food cooking on the stove can light up your brain. Of all the odors presented to the dogs, they responded more favorably to human odors than to the odors of canine companions. Additionally, the dog's caudate nucleus activated most significantly when the dog actually smelled someone it knew. A similar reaction occurs in people when they are shown photos of people they love.
"The caudate nucleus was activated in the dog
most notably when the dog actually
he smelled someone they knew."
In related research conducted in Budapest, researchers studied the brain activity of dogs when exposed to sound to see what happens inside a dog's brain when we speak to it. When the dog's brain was exposed to happy sounds, it responded in much the same way as the human brain by lighting up the auditory cortex. This illustrates the effective communication that occurs between dog and human and confirms the human-animal bond.
Through science, we have learned that our canine friends are social, emotional beings who respond to human smells and voices. They happily respond to our scent and respond to the tone of our voice. Science proves that a part of the dog's brain is associated with positive emotions and actually feels love for their human companions.
How do you know your dog loves you?
Here are some signs that your dog really loves you more than a fresh bag of kibble and a walk in the park:
Your dog is happy to see you. Your dog may jump and bark and be overly emotional when you walk through the door. Or maybe it's more gentle and simply wags its tail to the right at the sound of your greeting.
Your dog gives you presents. Sometimes your dog will bring you his favorite toy ready to play, but often he will give it as a gift. He wants to "share" his favorite possession with the person he loves.
Your dog puts you second to food. Besides food, your dog craves you! Dogs live "now". When they are hungry and given a bowl full of food, they forgo human interaction for the glory of good food. However, when the bowl is empty, the dogs want you! Many dogs want to cuddle their owners after a meal.
Your dog likes to sleep with you. Dogs are inherently alert to threats in their environment and lie in a defensive position when sleeping in the wild. They put their noses upwind to absorb threatening scents and their backs to other pack members to form a protective circle. The fact that they are willing to snuggle with you on the couch is a sign that they feel safe with you and consider you part of their pack. You are part of their inner family circle.
Your dog looks at you with loving eyes. Making direct eye contact can be interpreted as an aggressive action in the canine community. When two dogs meet, one looks away in deference to the alpha dog. When your dog looks at you with relaxed eyes and normal-sized pupils, he is giving you a loving look.
Your dog doesn't care about your appearance. If your dog cuddles you when you have bad morning breath, after a sweaty workout, or when you're having a crazy furry day, chances are it's true love. Dogs truly love us unconditionally.
Your dog follows you everywhere. If you feel like you can't take a step in the house without a dog at your heels, consider yourself loved. Dogs cling to you for more than just safety. Unlike other human companions, they can't get enough of your company.
Feel better? Now you can be sure of the affection your dog feels for you. Your dog loves you!
