Any dog owner knows that our canine companions have the remarkable ability to form unbreakable bonds of love and devotion with humans. The sight of your dog wagging his tail and running to greet you when you get home is evidence of this powerful connection. But do our dogs actually feel love for us, or are they just excited for their next meal?
Scientists have studied the canine brain and behavior to uncover the truth behind our dogs’ affection for us. Research shows that dogs are hardwired to connect with humans in a way that wolves, their ancestors, are not. This innate predisposition to bond with people means that dogs do indeed experience feelings of love and attachment.
In this article, we’ll explore the scientific evidence on dogs’ capacity for emotion. We’ll also look at the signs that your own pup feels a special affection for you. Understanding your dog’s expressions of love can help strengthen your relationship and create an even closer bond.
Scientific Research on Dogs’ Emotions
Recent scientific studies have explored whether dogs have the capacity to feel complex emotions like love. In 2015, a study published in the journal Behavioural Processes used MRI scans to analyze dogs’ brain activity when exposed to the smell of their owners (1). The scans showed increased activity in the caudate nucleus, which is associated with positive expectations and feelings of love in humans. This suggests dogs may experience similar emotions when interacting with their owners.
Another study by researchers at Azabu University in Japan measured the oxytocin levels of dogs when interacting with their owners (2). Oxytocin is known as the “love hormone” in humans and is released when bonding. The researchers found a significant increase in oxytocin levels when owners pet and gazed at their dogs. This indicates dogs may feel a similar attachment.
While we can’t know for sure what dogs experience internally, the neurological and physiological evidence indicates they have the capacity for complex emotions and attachment that could be described as love. More research is needed, but it seems dogs may indeed feel love similar to the love humans feel for them.

How Dogs Show Love
Dogs express affection in a variety of endearing ways that are adorable and heartwarming for any dog owner. Some of the most common ways dogs show love include excited greetings, cuddling, and following you around the house.
When you return home after being away, your dog likely greets you with extreme excitement—barking, jumping, wagging their tail, and giving you sloppy kisses. This is their way of saying “I missed you so much!” and showing how happy they are to see you (Source).
Dogs also love to cuddle up close to their favorite humans. Leaning on you, laying their head in your lap, and sleeping next to or on top of you are signs of affection. Cuddling releases oxytocin in both dogs and humans, promoting bonding and attachment (Source).
Following you around the house is another way dogs display their love. They want to be near their special person as much as possible. This loyal shadowing behavior shows they feel safest and most content by your side (Source).
Do Dogs Understand Words?
Research shows that dogs can learn the meaning of specific words and commands. According to the American Kennel Club, studies indicate dogs are able to learn the names of hundreds of objects https://www.akc.org/expert-advice/news/how-much-language-do-dogs-really-understand/. Words like “sit,” “stay,” “walk,” and “treat” are commonly understood by dogs when used repeatedly by their owners in the appropriate context.
However, this doesn’t mean dogs comprehend language at the same level as humans. As VCA Hospitals points out, dogs mainly understand words in isolation rather than in sentences or grammar structures https://vcahospitals.com/know-your-pet/eavesdropping-dogsdo-dogs-understand-our-conversations. Their understanding is based more on tone, body language, and associating words with rewards.
So evidence suggests dogs can learn the meanings of many words through repetition, but their overall comprehension of human language remains limited compared to people.
Do Dogs Recognize Individual Humans?
Yes, research shows that dogs can tell different people apart by recognizing their faces and voices. A 2013 study from the University of Tokyo found that dogs were able to distinguish between their owner and a stranger based on recordings of voices alone (Source). Another study revealed that dogs exhibit a greater neural response in brain regions associated with positive social stimuli when hearing their owner’s voice compared to hearing a stranger (Source).
Dogs are also able to recognize emotional expressions on human faces. Research shows they can distinguish between smiling and angry faces, suggesting they perceive the emotional content. Dogs even demonstrate left gaze bias when looking at human faces, similar to humans, indicating they process faces using the right hemisphere of their brains.
Experts believe dogs evolved the ability to recognize individuals over time through domestication. This aided their ability to interact with and receive care from humans. So when a dog runs to greet their owner happily, it’s not just because of familiar smells – they actually recognize their beloved human’s face and voice!
Interpreting Dog Behavior
Dogs communicate through various forms of body language and vocalizations. According to the VCA Hospitals, dogs use their eyes, ears, tail, and overall body posture to convey different emotions and meanings. For example, a dog holding its tail straight up signals confidence, while a tail tucked between the legs can mean fear. Ears that are erect or perked forward suggest alertness, while ears pulled back flat against the head often indicate aggression. Eye contact can communicate aggression in some contexts or bonding in others.
Vocalizations like barks, growls, yips, and whines also have meaning. As explained by Tuft University’s Center for Shelter Dogs, a playful bark tends to be higher pitched with short gaps between each one. Warning or alert barks are often low and guttural. Howling can indicate loneliness, while yips and whines demonstrate excitement or appeasement.
By carefully observing a dog’s body language and vocal cues in context, humans can better understand their emotional state and needs. With time and experience, we can learn to “speak dog” and more deeply bond with our canine companions.
Bonding Behaviors
Research shows that when dogs interact positively with their owners, such as through petting or play, both the dog’s and human’s oxytocin levels rise. Oxytocin is a hormone involved in social bonding, and higher levels lead to greater feelings of love and attachment [1]. This is similar to the oxytocin response between human parents and infants, suggesting dogs view their owners as family members.
One study found that when owners gazed into their dogs’ eyes, their oxytocin levels rose by 130% – the same amount as between a human parent and baby. The owners also saw a rise in oxytocin when their dogs simply stared back at them [2]. This chemical bonding through eye contact is a sign of the deep attachment and love between dogs and their humans.
Because of this hormonal response, the bond between dogs and their owners can feel as strong as between a parent and child. Dogs truly attach to their humans and crave close contact. When you cuddle, play, or gaze at your dog, both your oxytocin levels rise, reinforcing feelings of love and trust.
Signs Your Dog Loves You
One of the clearest signs your dog loves you is how excited they get when you return home after being away. Dogs are pack animals and form strong attachments to their family members. When you’ve been gone for even a short while, your dog is likely to show their excitement through jumping, barking, tail wagging, whimpering, and running around in circles.
Another sign of affection is when your dog maintains eye contact with you. Dogs that truly love their owners will hold eye contact for an extended period. This helps strengthen the bond between you. Making eye contact triggers oxytocin production in both dogs and humans, which is the “love hormone” responsible for feelings of affection and attachment. If your dog frequently locks eyes with you, it’s a good indication of their loving feelings toward you.
Ways to Strengthen Your Bond
Spending quality time with your dog is one of the best ways to strengthen your bond. Simple activities like taking them on walks, playing fetch, or giving pets and cuddles help reinforce the connection between you. Set aside dedicated time each day focused just on your dog without distractions from work, phones, etc.
Training also serves as bonding time, with the extra benefit of better communication and behavior skills. Work on basic obedience or teach fun new tricks together through positive reinforcement techniques. The shared experience of working toward a common goal brings you closer. Keep training sessions relaxed, rewarding and fun.
Playing games helps satisfy dogs’ natural instincts in a bonding way. Take time for interactive play like tug-of-war or fetch. Puzzle toys also encourage mental stimulation and connection through cooperative problem-solving. Laughter and silliness in play deepens the lighthearted joy in your relationship.
With a little daily effort focused on quality time together, you can continue strengthening the loving bond with your loyal companion.
Conclusion
In conclusion, there is strong scientific evidence that dogs are capable of love and attachment towards their human caretakers. Studies using MRI machines have detected bonding-related brain activity in dogs, similar to what is seen between human mothers and children. Dogs that have been separated from their owners also exhibit signs of distress, further indicating a strong emotional bond. Behaviors like tail wagging, face licking, nuzzling, and wanting physical closeness are indicators that a dog feels positively towards someone. There are many ways we can strengthen our bond with our canine companions such as through play, training, gentle care, and quality time together. While we may never fully understand canine emotions, it is clear that dogs return the love and form profound emotional connections. If you treat your dog with compassion and care, they are likely to love you in return.
