I can sympathize with being the hated neighbor thing. We called once when I was really little about our neighbors dogs. But they were scum bags, in all honesty.

I think it comes down to what's more important to you, really. No one is getting hurt, but YOU are having to change and alter your activities of daily living because your neighbor will stubbornly not listen to your very kind requests.

Plus, if you had to call on her before... don't you think maybe she doesn't know how to take care of animals? That's certainly a thought too!
