True love has four paws
According to our brains, we bond with our dogs in the same way. When you look at your dog, your brain produces more oxytocin. It works both ways — recent studies have shown that just looking at each other causes your dog’s oxytocin levels to go up, too.

It takes a pet parent to understand what all the fuss is about the bond or perhaps, love shared, between pets and their humans.
As a single pet parent — who has never had any human kids — I should know, right? Perhaps. But many times, in the over 50 years that I have lived with pets, people have found me strange because of the relationship I have with my pets and the things I do for them.
As pet owners (dogs, cats, birds, fish and every other pet in between), we readily acknowledge that we love our pets. But, our love relationships with our dogs may be the most easily recognizable. I mean really, why do we get out of a warm bed and take them outside early in the mornings to go potty? Why do we leave a restaurant before dessert and head home to feed them? Why do we immediately forgive them after they chew our favorite slippers?
I will never forget being asked, in the past — a lingering question that remains to this day — how do I know my pets (dogs) love me back?

The human–animal bond
I read a study from the early 1930s by an Austrian scientist named Konrad Lorenz, who won the Nobel Prize in Physiology or Medicine in 1973. He is considered a founder of modern ethology, the study of animal behavior — imprinting, in particular.
The story goes that he kept a collection of goose eggs and waited until they hatched. When they emerged, the newly hatched goslings followed the first moving object they saw — in this case, Lorenz himself.
Lorenz continued to study this type of animal behavior, which became known as imprinting. Later on, scientists found that there’s often a window of time in which imprinting has to happen in order to stick. In some species, this window may be as short as 30 minutes.
Imprinting in the animal kingdom is so powerful that if a lamb’s mother dies after giving birth, and the lamb is introduced to another mother within 30 minutes, that lamb will bond with the new mother (and vice versa) for the rest of their lives.
After Lorenz’s studies, scientists discovered that the feel-good hormone oxytocin is involved in imprinting. Oxytocin is sometimes called “the love hormone” or “the social hormone,” because it is released when humans bond socially or romantically and triggers feelings of happiness.
Oxytocin is an important part of mother-child bonding in both humans and other mammals. This hormone helps a mother bond to her infant while nursing.
According to our brains, we bond with our dogs in the same way. When you look at your dog, your brain produces more oxytocin. It works both ways—recent studies have shown that just looking at each other causes your dog’s oxytocin levels to go up, too.
On a biological level, our brains use the same neurological pathway to process our love for our pets and our love for our children. It’s the same love hormone. Studies have shown that the same parts of the brain light up when people look at photos of their children and photos of their dogs.
Science tells us that the human —dog bond is mutual: we both experience happiness, and we both benefit.
