both my patterdale bitches are bold as anything and put any dog in there place, the older one had a go at a bull terrierxpatterdale for trying to touch her rabbit and shes half the size of him and now he kisses her arse, i think its because they have both grown up around all sorts of dogs collies,lurchers,terriers,spaniels so they have learnt to hold there own
my youngest bitch used to be timid but when i took her over next door a few times were there are 4 dogs that love nothing better than a good play fight she soon came out of her shell
