"The results of the present study indicate that early separation of
a puppy from the litter is an experience that may increase the ani-
mal’s chances of showing potentially problematic behaviours as an
adult. Moreover, this effect can be further potentiated by the puppy’s
very first environment. It is well known that experience, genetics
and environment jointly influence most aspects of behaviour, exert-
ing interactive effects (Gottesman and Hanson 2005). In dogs, as in
human beings, the socialisation period is associated with the develop-
ment of social and environmental behaviour patterns, including those
associated with learning," the study reads.
