Personality traits used in the questionnaires applied to police cavalry officers and veterinarians to evaluate horses’ personalities.

Generalized linear mixed models results showing that the abnormal behaviours exhibited by police horses during the sham feeding experiments were influenced by individual variation.
Fig 1.
A. Personality traits of police horses in relation to the first two components of the Principal Component Analysis with Varimax rotation. The first component was related to the traits aggressive, reliable, irritable, cooperative, equable and stubborn, and the second component was related to curious, intelligent, playful and active. B.Spatial distribution of the loadings presented by the 46 horses in relation to the first two components of the Principal Component Analysis with Varimax rotation according to their personality traits.
Table 4.
Loading values of personality traits extracted by the Principal Component Analysis with Varimax rotation using the mean scores given to police horses by their rider and veterinarians.
Table 5.
Significant correlations between personality traits obtained from the Principal Component Analysis and the behaviours expressed by police horses during a novel object test.
Table 6.
Generalized linear models results showing that the horses’ lameness cases were influenced by the horses’ personality traits.
The results are shown for the questionnaire ratings (veterinarians and riders) and for the behavioural measures (PCA loadings with quadratic transformation).
