In our city, a call to the county animal services would be clearly preferable to going on to the person's property in a case of neglect or nuisance (non-stop barking qualifies as a nuisance), because many people have that wild west attitude about property ownership.

People differ dramatically in their views of grooming and medical intervention, though. To me, excessive medical intervention borders on cruelty to the animal, but others believe in it wholeheartedly (and with their whole wallets).
