I would not believe the word of the policeman. I would see the laws with my own eyes. County and city officials have been known to give out incorrect information. I hate that so many ordinances seem to favor the dog owner. You must have some recourse, commercial operation or not. Well, I don't favor the dog owner and I've owned a few dogs in my life and love dogs.
My dogs were kept at home-it's really not brain surgery, but apparently, there are quite a few brain-dead dog owners who can't seem to corral one single canine. They also seem to think that just because we can eat chickens, they are less important than a dog. Never saw a dog give you anything you could eat (except, maybe the dog itself, if you're Korean-my son lives there) so why is it more valuable than a chicken? But, I digress. If the authorities won't take care of it, I guess the chicken owner has to.
