How Do Dogs Form Attachments to Humans? A Scientific Explanation

Dogs are known for their loyalty and affection towards their human companions. The bond between dogs and humans is often described as one of the most special and unique relationships in the animal kingdom. But how do dogs form attachments to humans? This question has been the subject of research and debate for many years.

Studies have shown that dogs are capable of forming strong emotional bonds with their owners, similar to the way that human infants form attachments to their caregivers. These bonds are thought to be based on a combination of factors, including socialization, genetics, and individual experiences. Understanding how dogs form attachments to humans is important for both dog owners and researchers who are interested in the social and emotional lives of animals.

In this article, we will explore the latest research on how dogs form attachments to humans. We will examine the factors that influence the development of these bonds, as well as the ways in which dogs express their attachment to their owners. By gaining a better understanding of how dogs form attachments to humans, we can deepen our appreciation for the unique and special bond that exists between these two species.

The Science of Dog-Human Attachments

Research has shown that dogs form strong attachments to their human caregivers, similar to the attachment bonds that characterize human caregiver-infant relationships. The bond between dogs and humans is believed to be based on several factors:

  • Oxytocin: Oxytocin is a hormone that is released in both dogs and humans when they interact with each other. This hormone is associated with social bonding and has been shown to increase in both dogs and humans when they engage in positive interactions with each other.
  • Eye Contact: Dogs and humans both use eye contact as a way to communicate and build trust. Studies have shown that dogs prefer to look at their human caregivers rather than strangers, and that prolonged eye contact between dogs and humans can increase oxytocin levels in both species.
  • Positive Reinforcement: Dogs form attachments to humans who provide them with positive reinforcement, such as treats, toys, and praise. This reinforcement strengthens the bond between the dog and their caregiver and encourages the dog to seek out their caregiver’s attention and affection.

While the science behind dog-human attachments is still being studied, it is clear that dogs form strong emotional bonds with their human caregivers. These bonds are based on trust, communication, and positive interactions, and can last a lifetime.

Factors That Affect Dog-Human Attachments

There are several factors that can influence the attachment between dogs and humans. These factors include:

  • Early Socialization: Puppies that are exposed to humans and other dogs during their first few weeks of life are more likely to form attachments to humans. Socialization during this critical period helps puppies develop social skills and learn to trust humans.
  • Breed: Some dog breeds are known for their affectionate and loyal nature, while others are more independent. For example, Labrador Retrievers and Golden Retrievers are known for their friendly and outgoing personalities, which makes them popular family pets.
  • Training: Dogs that receive positive reinforcement training are more likely to form attachments to their owners. Positive reinforcement training involves rewarding a dog for good behavior, which helps build trust and strengthen the bond between dog and owner.
  • Personality: Just like humans, dogs have their own unique personalities. Some dogs are naturally more affectionate and outgoing, while others are more reserved. Dogs that are more social and outgoing tend to form attachments to humans more easily.
  • Owner’s Behavior: The way an owner interacts with their dog can also affect the attachment between dog and human. Dogs that receive affection and attention from their owners are more likely to form strong attachments. Conversely, dogs that are neglected or mistreated may develop behavioral issues and have difficulty forming attachments.

It is important to note that while these factors can influence the attachment between dogs and humans, every dog is unique and may form attachments differently. Additionally, the attachment between dog and human is a two-way street, and owners must also work to build and maintain a strong bond with their furry friend.

How to Strengthen Your Bond with Your Dog

Strengthening the bond with your dog is essential for a happy and healthy relationship. Here are some tips to help you strengthen your bond with your furry friend:

  • Spend quality time together: Make sure you spend time with your dog every day. Play with them, take them for walks, and give them plenty of attention.
  • Learn their body language: Understanding your dog’s body language can help you communicate with them better. This will help you recognize when they’re happy, scared, or anxious.
  • Train together: Training your dog is a great way to bond with them. It also helps establish you as the pack leader, which can make your dog feel more secure.
  • Give them plenty of exercise: Dogs need exercise to stay healthy and happy. Make sure your dog gets plenty of exercise every day, whether it’s through walks, playtime, or other activities.
  • Feed them a healthy diet: A healthy diet is essential for your dog’s overall health and well-being. Make sure you’re feeding them a high-quality dog food that meets their nutritional needs.
  • Take them on adventures: Dogs love exploring new places. Take your dog on road trips, hikes, or other adventures to help strengthen your bond.

Remember, strengthening your bond with your dog takes time and effort. But the rewards are well worth it. A strong bond with your dog can lead to a happier, healthier, and more fulfilling life for both of you.


In conclusion, dogs form attachments to humans through a complex interplay of various factors. The domestication and natural selection of dogs have made them adept at socializing with humans. They are sensitive to our emotional states and social gestures, and they can communicate with us using complex cues such as gaze alternation.

Chemistry and bonding go hand in hand, so paying attention to a dog’s natural body language is crucial in forming a connection with them. When a person is the source of all good things, the dog will form a connection with them. Psychology parameters have been developed to measure the degree of attachment that humans have toward companion animals.

Future research on interspecies attachment and bonding would involve investigations of the neuroendocrinological attachment mechanism in dogs and human-dog bonding as a manifestation of the specificity of dogs. It is clear that the attachment between dogs and humans is a unique and special bond that has evolved over thousands of years.
