I don't like labs or drooly breeds much.
I don't there should be a law banning them.
I only get scared of dogs showing aggressive behaviours.
And I'm not sure I'd know a pitbull if I saw one. Of the dogs I've met that look a bit like them - all but one have been well behaved. And the one - and it's equally nasty malamute friend - don't come to the park any more.
Of the Labs I meet - I would say about 8 out of ten are obnoxious and rude and prone to knocking people over. The better behaved ones have owners who train them and stop them from being rude.
