That pepper is the pack leader is obvious, but my question is:
in what situations is Pepper attacking Bruiser? What happens before?
Is Pepper in heat at the moment, or maybe the little bitch?
You don't know what will happen in your pack situation, when you work with Pepper, there is a chance that one of the other dogs will take "Mom's" place or that Bruiser and his sister are deliberately or not varivied in their actions, what actions that may be I cannot say from here, maybe it is just their presence.
Because:
With the age of 8 months the "pups" are old enough to live their own live, they have everything they need for survival, all instints are activated and Pepper shows very clearly that the territory is too small for 4 GSD's and she is not willing to share her living area with her descendants.
The situation with more than one dog is a case for a specialist, to train with you together. Otherwise you are taking the risk...
