How Attachment to Dogs and to Other Humans Relate to Mental Health.

It is unclear how pet ownership is related to mental health, with some previous research suggesting pet owners have better mental health, while other research suggests they have worse mental health. Some researchers have suggested that it may be more useful to investigate the bond people feel with their pets and how this may impact mental health; however, this too has led to mixed results. This study examined how owners' attachment to their dogs was associated with mental health and how this compared to their attachment relationships with other humans in a sample of 607 dog owners. Our findings indicate that both strong and insecure attachments to dogs are linked to poorer mental health outcomes, as was having an insecure attachment style in their human relationships. The adverse impact of strong attachment to dogs on mental health was mediated by these owners having an anxious attachment style toward other people, which in turn was associated with poorer mental health. The relationship between a strong attachment to dogs and poorer mental health was also moderated by gender, with this relationship being significant in women but not significant for men. Together, these results suggest a possible risk to mental health for owners who form a strong attachment to their dogs to compensate for anxious attachments in human relationships.
