People with secure attachment to their pets are less depressed, researchers find

For many people, pets provide unconditional love, companionship, and a sense of security. But not all human-pet relationships are beneficial, and some may contribute to stress and anxiety rather than relief.

Psychologists have been studying attachment theory for decades. This framework explains how people form emotional bonds, seek closeness, and manage separation. People with secure attachment tend to feel safe in relationships, while those with attachment anxiety may crave closeness but frequently worry about rejection or loss.

Just like with human relationships, people form attachment bonds with pets. Some form secure attachments, finding comfort in their pet and viewing them as a reliable source of companionship. Others experience anxious attachment, feeling excessive worry, distress, and a heightened need for reassurance when separated from their pet.

In our recently published research, my research team and I found that attachment anxiety is strongly linked to depression symptoms among owners. This suggests that well-being isn’t just about having a pet, but about the quality of your bond.

Strong bonds aren’t always healthy bonds

My team and I set out to explore whether the way people bond with their pets has a measurable effect on their mental well-being.

We surveyed more than 1,000 pet owners in the U.S. about their closeness to their pets; how often they engaged in activities like playing, cuddling, or spending time together; and whether they felt secure or anxious in the relationship. We also measured symptoms of depression to examine how different characteristics of pet bonds might influence mental well-being.

Our results revealed a clear pattern: Higher pet attachment anxiety was the strongest predictor of depression symptoms. In other words, people who felt overly dependent on their pets, constantly worrying about being apart from them, or whether their pet “loved” them back, were more likely to experience depression symptoms.

Surprisingly, simply feeling emotionally close to a pet was not enough to predict better mental health. While some may assume that a stronger bond with a pet automatically leads to greater well-being, our findings suggest that the quality of the attachment matters more than its intensity. People with secure pet relationships reported better well-being, while those with higher attachment anxiety experienced greater distress.

We also found that while frequent pet interactions were linked to stronger and more secure human-pet bonds, interaction frequency did not significantly predict mental health outcomes. This reinforces the idea that emotional security in the relationship, rather than just the frequency of interaction, is what truly matters for mental health.

Interestingly, people who owned both a cat and a dog reported more depression symptoms than those with only one type of pet. While our study did not determine the cause, one possibility is that managing multiple pets can add stress or increase the burden of caregiving.

How pet relationships shape your mental health

Our findings highlight that pet ownership is not a one-size-fits-all solution for mental health. The way people bond with their pets—whether they feel emotionally secure or experience anxiety in the relationship—may be just as important as pet ownership itself in shaping well-being.

This research also raises important questions about the role of emotional support animals and animal-assisted interventions. If pet ownership is going to be integrated into mental health care, it may not be enough to simply encourage pet companionship. Instead, the quality of the human-animal bond could be a key factor in whether pets provide comfort or contribute to emotional distress.

This study does not suggest that people should stop seeking emotional support from pets. Instead, it highlights how the way people bond with their pets can influence well-being in ways they may not always realize.

For those who rely on their pets for emotional support, recognizing these patterns may help foster a bond that feels reassuring rather than stressful. Pets can provide deep comfort, but caregiving comes with challenges, too. Reflecting on both the joys and responsibilities of pet ownership can help strengthen the human-animal bond, supporting the well-being of both pets and owners.
