behavior after a tragedy

Question
I am an owner of 2 female German Shepherds. One of which is spayed (Kia) and the other (Dakota) had pups almost 2 weeks ago. Kia is definitely the alpha dog. Eight days after the pups were born Kia got ahold of all 10 and killed them. It has now been a week since it happened and the two are still uneasy with each other. Dakota gets very upset when Kia enters her sleeping territory and results in her sleeping under the bed. Kia tends to growl at Dakota when she gets to close to her or when she enters Kia's bedding area. Dakota becomes very jealous and pushy when Kia wants attention from us and will push her way in the middle. It almost seems as though they are fighting over the alpha position. Is this normal with the circumstances? The atmosphere in the home is a little uneasy due to the accident and I am wondering if the 2 dogs will regain their sisterly bond again? Also should I separate the 2 for a little while? I love my dogs dearly and this unfortunate accident has taken a pretty big toll on all of us. I am at a loss on what to do.....

Answer
This was no "accident" it was improper stewardship on your part.  If you perceive one dog of two or more that you have in your household is clearly the more dominant of the two and proceed to allow the subdominant to breed, you are setting yourself (and those innocent neonates) up for a disaster.  NO ONE can intervene in this situation from a text box.  The enormous psychological, emotional and physical trauma experienced by the subdominant bitch in this situation IS UNCONSCIONABLE.

You require in person assistance from a certified applied animal behaviorist.  The bitch whose puppies were killed in this barbaric manner requires immediate veterinary attention,,,IMMEDIATE.  Find a certified applied animal behaviorist who can evaluate both dogs and the manner in which you are living with them, which is clearly not appropriate and is putting YOURSELF AT RISK.  Dog to dog aggression, especially to this extreme extent, is a strong predictor of dog to human aggression.  STRONG predictor.  Find a behaviorist (NOT a dog trainer) immediately at one of the following sites:
