There are more dogs than kids where i am, it's the countryside, have had dog bite bark and chase me into a 60 mph road twice, also been chased a few times on field/footpath runs 'he's not normally like this daahling he just thinks you're a burglar' seems to be a perfectly reasonable excuse.
One dog down the end of the road, one of those mini horses, broke its metal chain (which was so long the neighbours couldn't get to thei front door) 3 times, the final time chasing, biting and mangling the hand of another dog owner in our road.
It's when they're chasing my young children in the park that i get really angry, because they're only little.
But there's nothing you can do.
