Help me!

Two dogs came to my neighborhood a few months ago. They're skinny and might die. My mom already got us 2 dogs. One of those dogs really loves me. My family won't feed them or anything because my mom hates fur. (Yeah, I know.) Well, she is always threatening to kill them and shoo them away because she doesn't trust them. I really love them. I know I can't have them, that's not the issue. The problem is that she hates the 2 dogs. What do I do to make sure she doesn't call the Humane Society or just shoot them? They're not bad and she knows it. They'll love on me every day when I get home from school. And she knows that, too. So what the hell do I do?
