Atferd hos hund varierer med høyde, kroppsvekt, og hodeform

Stepwise backward elimination regressions revealed that, across the breeds, 33 behavioral traits all but one of which are undesirable in companion animals correlated with either height alone (n=14), bodyweight alone (n=5), CI alone (n=3), bodyweight-and-skull shape combined (n=2), height-and-skull shape combined (n=3) or height-and-bodyweight combined (n=6). For example, breed average height showed strongly significant inverse relationships (p<0.001) with mounting persons or objects, touch sensitivity, urination when left alone, dog-directed fear, separation-related problems, non-social fear, defecation when left alone, owner-directed aggression, begging for food, urine marking and attachment/attention-seeking, while bodyweight showed strongly significant inverse relationships (p<0.001) with excitability and being reported as hyperactive. Apart from trainability, all regression coefficients with height were negative indicating that, across the breeds, behavior becomes more problematic as height decreases. Allogrooming increased strongly (p<0.001) with CI and inversely with height. CI alone showed a strong significant positive relationship with self-grooming (p<0.001) but a negative relationship with chasing (p=0.020). The current study demonstrates how aspects of CI (and therefore brain shape), bodyweight and height co-vary with behavior. The biological basis for, and significance of, these associations remain to be determined.

Interessant.

Det kan man se hos hester også, at man kan analysere hesten ut fra hodeform og trekk i ansiktet Ei tok en sånn analyse av hesten min, og hun var så spot han. Hun fikk liksom forklart akkurat hvordan han var slik jeg har prøvd mange ganger, men ikke fått til. Hun hadde aldri møtt hesten, hun bare så bilder av han
