Maybe you feel like you wanna do something harsh to your brother but in the end you will regret it: bring your dog to the animal shelter and give her up there.it's hard but you know you can't stop someone from beating a dog unfortunately: or you can talk to your parents maybe they can punish your brother:.
If you get violent against your brother you will have turned into your brother because you will be using violence against somebody who doesn't know better. A normal dog however after a few of such treatments would not come near to your brother or even threaten to bite your brother if he comes near. You either have a dog with a learning disability or yourself the disability to make a credible story up.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
