Our dogs are our kids. It’s not rocket science—we love them, they love us. They look to us for comfort and care. We call them our fur kids or our four-legged children. So, even though it’s not news to us, it’s validating to see science confirm what we already thought was true: Our dogs are like children to us.

Children have been shown to explore the world most confidently if they have a strong attachment to their caregiver (usually a parent.) They use the parent as a secure base from which to explore their environment if they have learned that the parent is dependable and reliable, and this phenomenon is called the secure base effect.

In the recent study, The Importance of the Secure Base Effect for Domestic Dogs—Evidence from a Manipulative Problem-Solving Task, researchers conclude that dogs are bonded to their guardians in the same way that infants are bonded to their parents. They found that dogs use their guardians as a secure base, just as children do.

In the study, dogs were tested in each of two experiments and their behavior was quantified. In the first experiment, dogs were given the opportunity to obtain food from interactive dog toys, and the amount of time the dogs spent attempting to extract the food was recorded. The dogs were tested in three different experimental situations: 1) with their guardian absent, 2) with their guardian present and encouraging them, and 3) with their guardian present but silent and unresponsive. Researchers also recorded how much time the dogs spent in close proximity to their guardians as well as to the experimenter, who was present in all conditions.

The results of this experiment showed that the different situations had an impact on how long the dog manipulated the interactive toy in an attempt to extract the food. The dog manipulated it longer when the guardian was present than absent, but there was no difference in response to whether the guardian was encouraging the dog or remaining silent. The dogs spent an equal amount of time close to their guardian regardless of whether they were receiving encouragement or not. They spent more time close to the experimenter when their guardians were absent than when they were present, suggesting that the experimenter offered some security, social support or comfort in the experimental context.

The second experiment was designed to determine if the effects seen in the first experiment could be explained simply by the fact that in the situations in which the guardians were present, there were two people in the room, whereas in the guardian-absent condition, there was only one person. In other words, what if dogs are not affected by having their guardian as a secure base, but simply react to the presence of more than one person in the room? So, in experiment two, the first experiment was modified to include a fourth condition in which an unfamiliar person (rather than the guardian) was present along with the experimenter.

The results of the second experiment were that dogs manipulated the interactive toy longer in the presence than in the absence of their guardians, regardless of whether an additional unfamiliar person was in the room. The dogs spent more time near their silent, unresponsive guardians than to the unfamiliar person, who also refrained from interacting with the dog. The addition of the unfamiliar person condition allowed the researchers to determine that the guardian had a specific effect on the dog’s performance that cannot be explained by the presence of just any person.

Prior to participating in this experiment, all dogs were tested for their willingness to eat food in the absence of their guardians. They were also scored for their tendency to exhibit separation distress when kept away from their guardians. Interestingly, there was no relationship between the time spent manipulating the toys in the absence of their guardians and the amount of separation distress they showed, which means that the results of the experiments cannot be explained by a tendency of the dogs to manipulate the toy less because of the distress of separation.

This is the first study to demonstrate that the relationship between dogs and guardians is similar to the relationship between children and their parents in that both involve the secure base effect. This raises concerns about experiments into cognitive abilities that involve problem solving that is far more complex than in this study because the absence of guardians could significantly lower performance by the dogs.

It also confirms the view that most of us have about the canine members of our family—they are like kids to us!
