I will have to try something else.. I try to nip it in the bud but not always around when it takes place.

Are all the dogs spayed? Is any of this connected to heat cycles?
Three of the four are fixed, Ruby is not. and NO it happends just any time...

I would separate the offender when you cannot supervise.
I do when we are gone from the house.

Did you raise all of these dogs from puppyhood, or is there something in her background that could be playing into this?

Yes all of them. Two came from mid size breeders the other form a home breeder. Ruby was one that came from a breeder with about 6 different breeds. A very nice place... no issues there.

I started working with her when I run the sweeper. I have my eye on her when I start it up and correct her the moment she starts after one of the other dogs. I worked with her turning it (on & off ) several times. She did pretty well with it. But again that in only one small part of the aggression problem.
