And if this person convinces authorities that the dog is aggressive, the dog can be euthanized.
This person is not just immature. She poses a potential threat to all of your pets. Personally, if you wish to continue associating with her, my advice is to keep her OUT of your house and AWAY from your pets. Also, if you decide to continue spending time with her, write a list of everything she has done to your pets AND make sure your parents (assuming you're living with them) know everything about this.
If you doubt this, call the local shelter or Animal Control. Ask them what happens to a dog that bites someone, even if the person was harassing the dog. (And remember, that it will be your word against hers. She'll say that she did nothing.)
Oh, absolutely, I'm sure there are several people who've said this as well, but in terms of animal biting, the authorities kill first and ask questions, if ever, later.
I understand why they feel that it is necessary to put down a dog that bites for general safety and an inability to look into every case and get the entire story...But it absolutely means that it is the responsibility of the **owner** to PREVENT a bite from ever happening in any circumstances.
On the rest of this...
You need to cut ties with this girl. Tell your parents what she's doing if you need to in order to make sure that you have adult back-up on this to prevent her from coming to your home. She's going out of her way to torment you, and part of that is by hurting her fish. She knows it makes you angry, and so she's going to neglect it to death and continue this cycle until she can no longer get a rise out of you. It's very simple bully behavior, and it's pathetic. You don't need it in your life, and by taking away her ability to bother you, you may actually be helping her fish, and you're definitely going to keep your own pets safer.
I'm not sure that I'd call her a psychopath, there are very clear DSM-IV qualifications for this, but MANY teenagers and some young children WILL display these types of characteristics because they have not been taught better, they're looking for attention, something is wrong at home or school...the list goes on and on.
There is nothing realistically you can do to/about her, or to help her fish, and the only option left to you is to distance yourself from her and her ridiculously childish antics. It would be easier to make a new friend and have an actual friendship than it will be to continue dealing with this horrid child.
