Of course the humans are at fault Oldbat- but what then?
I am very glad I live currently in a country that has very strict registration, local and national, of all dogs- with some breeds or crossbreeds, as per vet recommendations, which are banned, and where anyone with docked ears or tail, are forbidden, and where it is properly enforced.
Whenever our dog is out with us off lead, in the woods, and anyone is around (VERY VERY rare) we always ask if they are afraid of dogs and if they want me/us to put on lead. They always say 'no, we love dogs'- but just in case. People's dislikes or fears have to be respected.
