Validation of the Socially Acceptable Behaviour (SAB) test in a Central‑Italy pet dog population.

: Aggressiveness is reported to be the most important public health issue related to both owned and free‑roaming dogs. Common approaches to assess canine aggressiveness are temperament tests. The main aim of this study was to evaluate whether one such test, the Socially Acceptable Behaviour (SAB) test, created to evaluate aggressive and fearful behaviour in dogs in the Netherlands, could be used reliably to assess dog aggression and fear in a population of owned dogs in Central Italy. Reactions to the test were recorded and compared to the owners' perception of their dog's aggressiveness using a validated questionnaire (C‑BARQ). Dogs showing aggressive reactions during the test obtained significantly higher (more aggressive) scores on the C‑BARQ subscales 'stranger‑directed aggression' (SDA p<0.001), 'owner‑directed aggression' (ODA p = 0.03), and 'familiar dog aggression' (FDA p = 0.006), than dogs who did not react aggressively. Logistic regression analysis revealed that 7 of the SAB‑subtests were predictive of the SDA score. The findings indicated that aggression directed toward unfamiliar people can be reliably assessed using the SAB test for a population of Italian pet dogs.
