“”I would shoot them to prevent them from biting me.””
So, you would just start shooting at them, not knowing if they even intended to bite you? Most dogs are not going to bite you. You would be shooting a non-feral animal. But I understand the fear of being bitten. I have been bitten by cats several times and it is definitely not fun.
I'm actually pretty smart. I've had a long lifetime that includes experience with all kinds of dogs in numerous situations. I know when I am in danger. If an owner actually loves her dogs, she must keep them from appearing to be a threat to my safety.
