Behavior variables observed in Strange Situation Test (D, dog; S, stranger; O, owner).
| Attachment | Score | |
|---|---|---|
| Owner PRESENT | D is mostly close to O (closest bodypart is within 1 m) when does not explore or play | 1 |
| D does not stand at the door (within 1 m) for more than a few seconds | 1 | |
| during the cube-carrying the D mostly watches or follows O | 1 | |
| when O first leaves, D follows O to door (within 1 m) | 1 | |
| when O leaves the second time, D follows O to door (within 1 m) | 1 | |
| when O enters, D approaches (within reaching distance) at once and wags tail | 1 | |
| Owner ABSENT | D plays with S (at least for 2 s) | −1 |
| any vocalization | 1 | |
| D stands by or orients at door (at least for 2 s−1, most of the time−2) | 2 | |
| when S enters, D does not great and tries to sneak out the door | 1 | |
| D is mostly at the chair of O (within 1 m) if not at the door | 1 | |
| ANXIETY | ||
| Owner PRESENT | D stands at door (within 1m; at least 2 s−1, most of the time−2) | 2 |
| D does not explore or play at least for 2 s | 1 | |
| D positions himself (hides) under/behind O's chair (relative to door or S) for at least 2 s | 1 | |
| as soon as O stands up D approaches door within 1 m (before O) | 1 | |
| D watches or approaches door while O is carrying cubes (for at least 2 s) | 1 | |
| any vocalization (if not clearly asking for the ball) | 1 | |
| Owner ABSENT | any contact seeking behavior with O before the separation | 1 |
| at 1st separation D vocalizes or runs around up and down or scretches door | 1 | |
| at 2nd separation D vocalizes or runs around up and down or scretches door | 1 | |
| D follows S to the door when she leaves (within 1 m) | 1 | |
| D plays or lies down comfortably (head down) but not at door for at least 2 s | −1 | |
| ACCEPTANCE | ||
| Owner PRESENT | D approaches S when she 1st enters (at once, within reaching distance) | 1 |
| D gets in physical contact and wags when S 1st enters | 1 | |
| At any time | D takes toy to S (not during play) | 1 |
| D seeks physical contact (jumps on, snuggles up to, nudges) during the episodes | 1 | |
| D avoids S during play (stands off, avoids her touch) | −1 | |
| Owner ABSENT | D gets in physical contact and wags when the S enters 2nd time | 1 |
| during cube carrying D mostly watches (1) and also follows (2) S | 2 | |
| D plays with S also during separation (at least for 2 s−1, most of the time−2) | 2 | |
| D is close (closest bodypart is within 1 m) to S during separation (at least for 2 s−1, most of the time−2) | 2 | |
