the dogs are getting mad, and bite kids and elderly people
This sentence alone means that the time to be nice is over. I have children and was faced with a similar situation before.
First, call the police. Tell them that this lady's dogs are attacking people. Not stray dogs, but hers. If she denies then they are good to go to the shelter. You will probably have a few backers on your side.
Then, if this doesn't stop I would personally threaten her
- first about the fact that she will be sued, which means money and possibly jail
- then that she will have a complicated life if the dogs happen to look at my children. And by complicated I mean hell complicated. Like afraid to leave her apartment complicated.
Sorry but there is a limit to everything. I love animals, had and have dogs and cats but there are priorities. Philosophical approaches work until a kid is seriously wounded and suddenly it is the fist of the father which helps her to understand that she lives in a society with more than herself and her dogs.
EDIT: just to be extra clear
and suddenly it is the fist of the father which helps her to understand that she lives in a society with more than herself and her dogs
is the unfortunate consequence which may arise if she is not stopped quickly.
This is certainly not the right thing to do, not because she does not deserve it (she does by being an indirect threat to the children) but because there are better ways to effectively stop her (like placing her in a psychiatric hospital where she belongs).
I would like to see the supporters of the kind and soft approach to this idiot lady explain their philosophy to the parent of the child who has been bitten on the face by one of these dogs.
