In my case it is not a busy road by any means and yes he will run them down,we have seen where he ran off the road and hit them, the last one was my daughters dog,she lives on the other side of the easment she was calling her aby dog and he was already on her side of the easment and she saw him swerve to hit the little weiner dog , all h... broke loose, see we own this easment as in it is part of our land, he can't do anything to it W/O our permission he only has a right to come and go on it.
We had it blacktoped so he could no longer run off the road to hit any animal unless he slows way down as it now has a nice shoulder.
Can't say a much good about this fella,sept he didn't turn out to be such a nice fella after we let him have the easments and that ment utility easments as well , it's messed up but at least it's the only one like that around here.
His new wife seems like a nice person, but guess i will never really know he seemed nice too once.
