Hey there. I rescued my sweet female Australian Shepherd, Annie, a little over 3 months ago (as of right now she is 5 1/2 months old) and I have noticed her being more aggressive towards me. She has been biting (not nipping) and actually breaking the skin.
She also starts getting this stare in her eyes that is very unsettling. The other day, I was doing research on my computer and she was in the room with me laying down. All of a sudden, she put her paws up on the chair arms and lunged toward my face, trying to bite me.
She went through 5 weeks of obedience training with me and it ended a little over 3 weeks ago. Whenever she gets in this mood, I become firm with her and tell her no then put her in her crate for 'time-out' but it doesn't seem to work.
I love her to pieces and will not give her away but I honestly do not know what to do. Any help/advice will be appreciated!
