German Shepard Bite

My German shepherd is aggressive!?

My mother has a German shepherd is a little chicken shit but a spell if we put in a cage with my other dog. You can not feed without getting bit. My father gave him the finger and told me to do and since he tried to bite me. I can not even establish basketabll without him crazy. How I can get it to stop. I can not, my dog, her mother and she used to pay something for him, but the food and toys

Sounds like you need help a trainer.
