The present meta-analytic review examined the associations and differences between interpersonal and pet attachment bonds, considering the attachment dimensions of anxiety and avoidance. The work complies with the PRISMA guidelines and was pre-registered on PROSPERO. The literature search was conducted by consulting the PubMed, PsycInfo, PsycArticles, MEDLINE, and Google Scholar databases, which yielded 12 studies. The meta-analyses showed a moderate positive association for the anxiety dimension ( r = .39) and a weak positive association for the avoidance dimension ( r = .16) between interpersonal and pet attachment. The levels for anxiety and avoidance dimensions in pet attachment were also significantly lower than those in interpersonal attachment ( p-value <.001). The findings suggest that there would be moderate correspondence between the two attachment bonds for the anxiety dimension, whereas avoidance strategies might not be fully transposed to pet attachment bonds. Compared to interpersonal attachment, pet attachment also seems to be characterised by lower levels of attachment insecurity and this could be a useful element to consider in therapeutic contexts.
