Pet and working dogs raised with humans are known to form attachments to their caregivers and other humans with whom they have a stable relationship. Attachment style varies across dog-human dyads, with securely attached dogs exhibiting the secure base effect, an ability to find comfort in the presence of an attachment figure in unusual situations, allowing for greater exploration. The secure base effect is also known to facilitate interactions with unfamiliar individuals. Dogs who engage in Animal Assisted Activities (AAA) are often asked to engage with unfamiliar people in unfamiliar environments, therefore it is possible that dogs with a secure attachment to their human handlers may be more prepared for success in this role. This study evaluated the behavior of 16 dogs who engage in AAA. Using a secure base test dogs were categorized as demonstrating secure (exhibiting the secure base effect with their owner/handler; n = 8) or insecure (not exhibiting the secure base effect; n = 8) attachment styles toward their handlers. Later the dyads participated in a mock animal assisted activity session to evaluate their working behavior. Our findings indicate that independent of attachment style, dogs who engage in AAA spent significantly more time in proximity to, and touching, the AAA participant than their handler (p < 0.001 for both proximity and touch). However, on average the AAA dogs spent significantly more time gazing at their handler than at the participant during the session (p = 0.03). Dogs with an insecure attachment style appear to have driven this effect as evidenced by a non-significant trend suggesting that they gazed longer at their handlers than at the participant (p = 0.07), whereas secure dogs did not display the same trend (p = 0.24). This could suggest that while their training mandates proximity and interaction with unfamiliar people, dogs who engage in AAA may be using gaze to maintain contact with their handlers, especially in the absence of a secure attachment where prolonged comfort seeking from the attachment figure would be expected.
