I'm my opinion time outs don't really work with dogs. U have to be the pack leader and yell in a louder than usual tone (scary sounding) like the pack leader of dogs would growl or bark to put her in place. She thinks she's the leader and that you are all under her command. Don't remove her from the situation but yell and then let her follow. It has to be a loud yell that she knows you are angry and mean business. Ignoring her after yelling will work better than time outs. I stumbled upon this remedy one day when I was breaking up so many fights with my 2 boys and also the younger one was starting to bite my kids! I went to break them up and I put my finger right in his mouth
it was so painful! Anyway the next morning another fight broke out and I lost it... I screamed in such a scary loud tone that they both stopped and instant peace!! They both wanted to remedy and give me kisses... And honestly after that I can say I have maybe had one incident in the past month! It has to be a louder than usual yell and u can't follow up with a stern "no" so that if it happens again they learn.
