BeyondTheEnd - you mentioned in another post that this BF of your mom sexually abused you. Does your mom know he did this? You mentioned you have an older sister and I see you're 16 -could you go live with your sister? Can you ask your mom to turn the dog into the humane society or ask your sister to take him? You're old enough, that you could move out if you're in danger. If he does ever try to hurt you, please call 911. It's better to lose the house and be safe. Often abusers will abuse animals to get the victims to comply. I'm sorry you're going through this.
