The aggression toning down seems to apply mainly to male dogs and same sex aggression - I don't think that it has quite the same effect on females, based on experience and what I've been told. So spaying Ka might tone down her aggression toward Blaze, but I won't say for sure that it will, so don't set your expectations too high in that regard. And if it's Blaze starting the fights, then spaying Ka might not solve anything. I believe that you'll probably have to find other ways to keep them from fighting by seperating them and also figuring out the root cause. If a spay works, great! I have a feeling it won't unless hormones really are the root cause, and instead it's likely either: Blaze and Ka's temperaments clash and they just don't get along (not all dogs like everybody), there is not enough structure in the way that they're living and so they're aggressing toward eachother out of frustration, it could be inherently breed based (some breeds are more prone to dog aggression and/or same sex aggression than others), or it could be something else entirely. Dogs have lots of reasons for acting out in different ways. Also, is Ka starting the fights, or is Blaze? Have you noticed what seems to trigger a fight?

The first fight was triggered when i was away and a friend was feeding the dogs for me she fed them next to each other blaze tried to take some of ka's food and it happened it was ka who started it defending her food. 2nd fight happened when Ka got in heat and blaze was growling whenever ka just walked in front of her and one day they both just snapped and fought, .
Blaze is the dominant female of my pack and ka knows it already they seemed to get along perfectly till that food incident and everything went bad after that
