Abstract
Impulsiveness
describes the inability to inhibit behaviour in the presence of salient
cues. Trait-level impulsivity exists on a continuum and individual
differences can be adaptive in different contexts. While breed related
differences in behavioural tendency in the domestic dog (Canis
familiaris) are well established, the phenomenon within lines of a breed
which have been selected more recently is not well studied, although it
may challenge the popular notion of breed-typical behaviour. We
describe differences in impulsivity between and within two dog breeds
with working and show lines selected for different levels of
impulsivity: Border Collies
(herding work) and Labrador Retrievers (gun work). Recent show line
selection might have lessened differences in impulsivity between breeds.
We tested this hypothesis on a dataset of 1161 individuals assessed
using a validated psychometric tool (Dog Impulsivity Assessment Scale -
DIAS). Collies were more impulsive on average, consistent with the
original purpose of breed selection. Regarding line, working Collies
differed from working Labradors, but show lines from the two breeds were
not significantly different. Altered or relaxed artificial selection
for behavioural traits when appearance rather than behaviour become the
primary focus for breeders may reduce average differences in impulsivity
between breeds in show lines.
