A problem child

Her name is Apples. She came from a Rescue.

I do not know anything about her parents or background.

She is not an only dog. She doesn't get along with the old male dachshund and she has attacked him twice already. She also tries to dominate the other female dachshund by biting at her spout.

I need help with this dog. She is owning the household and wants the older dogs out of the picture, especially the male dog.
