Behavioural categories that indicate secure base effect.
a) Exploration, b) Individual play, c) Social play. Proportion of behavioural occurrences in the two groups of dogs across the 8 experimental episodes (group means with SEM are shown). Asterisks indicate significant differences between dogs' groups (see text for details) : *P<0.05; **P<0.01.

Behavioural categories that indicate proximity seeking.
a) Approach, b) Oriented to person. Proportion of behavioural occurrences in the two groups of dogs across the 8 experimental episodes (group means with SEM are shown). Asterisks indicate significant differences between dogs' groups (see text for details) : *P<0.05; **P<0.01.

Behavioural categories that indicates searching.
a) Scratch door, b) Oriented to door. Proportion of behavioural occurrences in the two groups of dogs across the 8 experimental episodes (group means with SEM are shown). Asterisks indicate significant differences between dogs' groups (see text for details) : *P<0.05; **P<0.01.

Behavioural categories that indicate comfort seeking.
a) Physical contact with person, b) Physical contact with chair. Proportion of behavioural occurrences in the two groups of dogs across the 8 experimental episodes (group means with SEM are shown). Asterisks indicate significant differences between dogs' groups (see text for details) : *P<0.05; **P<0.01.
