I own and trained working dogs for close to 40 years now.
Your dog needs to be properly trained and under control.
If someone is on public land, road right away or what ever and your dog attacks. You are at fault and your dog is at fault.
I will not stand by and get bite by a untrain, uncontroled dog.
Then if your dog does bite me I’ll do every thing in my power to see that you are charged properly and sued to pay for the medical bills and other costs.
It is easy keep your dogs properly trained and under control and you will not have a problem
