Canine Behavior/growling sisters

Question
We adopted two 9 wk old Shih Tzu’s. They are 8 months old. About 2 months ago, they have started growling and biting each other.They don't do this with humans. After they fight, or we pull them apart, they seem better and fall asleep together. We separate them, hold them firmly around the back oh the neck and say NO!!!  They don't listen. This happens about 2-3 times a day and sometimes not at all. They are very sweet and precious. They do play well together and like to be near each other. They are not fixed yet.
Thank you in advance for your help.


Answer
I've seen many litter mates of the same sex in one household who develop an aggression problem toward one another.  This is always the result of temperament being very equal and requires you to be instructed on how to determine which dog is really top ranking, how to interact with your dogs based upon that observation, and how to de-escalate what will soon become a serious dog to dog aggression problem.  You need to contact a credentialed behavior expert (NOT a dog trainer with make believe credentials from some dog training group.)  To do this, you might want to call a veterinary college within a reasonable driving distance and they might be able to provide you with a name, or names, of people who understand how to determine rank, teach you how to observe body signals, and teach you how to rehabilitate these dogs' relationship with one another.  It simply can't be done in this venue.
