Dogs look at the world in a different way than we do. Pack structure is their world. Your dog lost her male leader and yes, she is grieving heavily. You just need to give her time. I know she doesn't appear to want much to do with you, but keep doing what you have done. When you can find the time, and when YOU are up for it, give her some "one on one" time and attention. Even if it is just a 10 minute walk with you alone. Each dog needs their "mommy" time alone with you for the bond to completely develop. She will eventually adjust to you being her leader. The aggression toward the other dog at night, tell me that more than likely your mixed breed is beginning to recognize that you are now assuming the leadership position, and although may not appear to be accepting the situation when she is around you, she may be challenging your other dog for her spot as the second in the pack rank. If your purebred is the omega dog while this mix is more of an alpha personality, they will find their comfort zone with each other. You can't find it for them. You might want to consider keeping them separated at night. If that means keeping one in your bedroom and one outside the bedroom if you don't crate them and they are allowed to roam the house, then do that. Close the door to the bedroom. Switch the dogs every night, or every other night. Try to treat them in the same manner, be their leader, and allow them work out their pack rank between them. You may find that as time goes on, your mixed breed will be constantly challenging your purebred for your attention. If that happens, come back and post. I will help you work through it.
