I find it essential to control exactly which branch I push from and to.  
So what you want to do is

git push <remote> <localbranch>:<remotebranch>

Git push with no arguments...I have nevere done that so I can't say,  
but I suspect it pushes for each of you local tracking branches, so it 
depends on how you made the branch in the first place.


What you want to do on DOGTAG_9_BRANCH  is create a revert commit,  that 
undoes the last commit,  and then push that to the
DOGTAG_9_BRANCH.


There is some discussion about merges versus rebases,  but I think the 
teams (IPA,  DS and now CS)  all want to go with the rebase approach.  
So before you push changes  to DOGTAG_9_BRANCH  you should do

git checkout DOGTAG_9_BRANCH
git fetch
git rebase DOGTAG_9_BRANCH

I like doing it as specific steps as I understand what each step is doing.

checkout makes sure I am in the right local branch.
git fetch pulls the changes down from the central repo to my local repo 
but makes *NO* changes to my local branch
git rebase only makes the changes, and will warn if there are any 
errors.  ONce that is done,  you will be able to push using

push origin DOGTAG_9_BRANCH:DOGTAG_9_BRANCH


You probably shouldn't be pushing to master,  unless you are working 
with Ade and Endi on some issue.
