Aggressive PitBull mix (i think jack rusell)
I got Penny when she was about 4 months old. I got her from someone that could no longer keep her due to their rental agreement. I live with my boyfriend and his 2 older dogs. I got her fixed after having her about a month.
She has recently started attacking my boyfriend. Her pupils will dilate and she lunges for him and then growls/barks after she jumps. I have a hard time restraining her. She is very protective over me. The boyfriend is physically abusive at times toward me, and has toward her too.
I don't know why this has started or what to do.
