This could be long, but I will try to sum it up!
Moose is two, we got Mimi almost 5 months ago and she is now 18 months. We let both sleep with us at night. For the last few months, Mimi will attack Moose in the middle of the night. We will all be sleeping and bam....she is in attack mode!
I feel she is having Protective, Territorial, and Possessive Aggression towards Moose at night. SHE DOESN'T WANT HIM ON THE BED AT ALL!

She growls at him when he gets up on the bed.
We tried putting her on her back and telling her no growl and wait tell she is calm and submissive (I have been watching EVERY Dog Whisper show I can find!!

) When she get up she goes back into her mode!
I bought a crate

and thought we would make her sleep in it. She doesn't like it!

We have very long and sleepless nights when she is in the crate!
I really want her to be able to sleep with us, but I want her to know that she is NOT the Dominant one and she in low in the pecking/pack order!
HOW DO I MAKE HER TRULY UNDERSTAND THIS???
