Behavior and temperament measures for the 10 most popular dog breeds.
Behavior and temperament measures for the 10 most popular dog breeds in the AKC database, years 1926–2005. Measures are defined in Table 1.
Figure 2.
Correlations between measures of breed popularity and behavior variables from the C-BARQ questionnaire.
Each panel displays Pearson's correlations between one measure of breed popularity (total number of dogs, breed volatility, rates of increase and decrease around popularity peaks) and the 14 behavioral variables assessed by the C-BARQ questionnaire (Table 1). The correlations are displayed both graphically and numerically in the first table column. Confidence intervals (displayed graphically) and values (reported in the second table column) are bootstrapped owing to non-normality;
values adjusted to control the false discovery rate [19] are reported in the third table column. The sample size for all correlations is
