Percentages (%) of the territories in eastern Finland during the hunting seasons of 2013/2014 and 2015/2016–2017/2018 where wolf attacks on dogs occurred, including the mean numbers and 95% confidence intervals of the territories with and without collared wolves that had wolf attacks. As we predicted, the proportion of territories where attacks occurred was higher in territories where none of the wolves have a collar than in other territories (chi-square for difference = 7.86; p = 0.005; n = 48) (n = 22 for collared wolves, n = 48 for uncollared wolves).
