Abstract
In order to assess dogs' personality changes during ontogeny, a cohort of 69 Border
collies was followed up from six to 18-24 months. When the dogs were 6,
12, and 18-24 months old, their owners repeatedly filled in a dog
personality questionnaire (DPQ), which yielded five personality factors
divided into fifteen facets. All five DPQ factors were highly correlated
between the three age classes, indicating that the dogs' personality
remained consistent relative to other individuals. Nonetheless, at the
group level significant changes with age were found for four of the five
DPQ factors. Fearfulness, Aggression towards People, Responsiveness to
Training and Aggression towards Animals increased with age; only
Activity/Excitability did not change significantly over time. These
changes in DPQ factor scores occurred mainly between the ages of 6 and
12 months, although some facets changed beyond this age. No sex
differences were found for any of the tested factors or facets,
suggesting that individual variation in personality was greater than
male/female differences. There were significant litter effects for the
factors Fearfulness, Aggression towards People and
Activity/Excitability, indicating either a strong genetic basis for
these traits or a high influence of the shared early environment. To
conclude, from the age of six months, consistency in personality
relative to other individuals can be observed in Border
collies. However, at the group level, increases in fearful and
aggressive behaviours occur up to 12 months and for some traits up to
two years, highlighting the need for early interventions. Follow-up
studies are needed to assess trajectories of personality development
prior to six months and after two years, and to include a wider variety
of breeds. © 2016 Elsevier B.V.
