We do have a 4 yr. law for rabies here, I just don't bother with it, My dogs are never out alone, we live on acreage also and they hike the trails every day. I still won't take the chance of the side effects from those shots. In all these years the only time I did have a sick dog as after the rabies shot and I almost lost my dog so it put me off shots forever.
I don't worry about my dogs biting, they are all therapy and have CGN and are non aggressive. The animal control here couldn't be bothered checking up on stuff like that, my vet knows where I stand on shots and if I ever did need care for my animals she would never refuse me.
I'm following the increase on autism and the controversy surrounding shots being the cause also helped me make my decision.
There has and still is much talk about the chicken pox vaccine being the cause of many cases of multiple sclerosis also....darned if we do and darned if we don't.
