Hi pet people! Feeling fragile with the dog pack situation so thought I would drop in here

Please bear with me............
Our doggie re-introduction is continuing but is proving to be an up and down process. What I am seeing is a lot of possessive aggression behaviour from Toki (possessive over me, mainly, and then also some continued general dominance assertion behaviour). For example; I had the two girls in the backyard together, muzzle on Toki; other two inside, and I just stayed relaxed and calm and hung clothes on line and pottered about for 10 minutes or so ignoring them. The whole time Toki shadowed me and kept Lucy right away (in fact hiding under the steps) by dominant body posturing and herding. Without muzzle she would have attacked I think, but without me there probably they would be okay
I downloaded one of Cesar's books onto my Kindle and read the whole thing today

and have written down all the 'rules'. We are having a family meeting to discuss the consistent implementation of the rules.
What I am seeing is: a somewhat insecure dog who is nonetheless naturally tending to be dominant with a very high energy level.

A dog who has not been set clear rules, boundaries and limitations and is now somewhat unbalanced and unstable. A dog who is not getting enough exercise. Latest escalated behaviour triggered by both the age (2yrs supposed to be socially maturing) and the coming into season of herself and the lower ranking female at the same time. Phew!
Am determined to stay positive and work this through over the coming weeks and months.
* Lots more structured excercise ( I need it too); correct walking technique!
* Consistent rules boundaries limitations - calm assertive leadership!
* Establish basic obedience training - sit, stay etc. (yes, we have been slack about that too

)
At the moment, Toki goes into the separate run at night and then we swap them during the day. Lucy copes with this quite well but Toki stresses at times initially when put in, then settles down. Tonight I put Saffie in with her as a calming influence. Do you think this is the right strategy to go with at the moment while we continue with the overall plan?
If you got this far, thanks for reading this Chapter in our Book of Dog Woes.....

It helps to write it down and get it out there; I need to stay calm and focused and happy so I can be a better pack leader
