I need help please!

I know this is not the app for this but im trying to get as much help and understanding that I can. I live in Ontario Canada and my boyfriend owns a pitbul, his parents sold it and the humane society for dogs got a hold of him and said that my boyfriend cannot get his pitbull back and that they will kill the pitbull if he stays in the gta! what can i do about this? has anyone experienced a situation like this? i need help please I am stressed, pitbulls are not all harmful and i dont want him to die, thepitbull  does not deserve that he is just a baby! please help me
