[kp&nala]

as some of you know i've posted in the past about how "rowdy" nala is, well it hasn't changed, lol. we've tried alot of things but they don't seem to work. i think one of my biggest problems was getting everyone else in my house trained. nala has gotten to where she get's so wired up that all she wants to do is attack you and i do mean attack she barks, growls and shows her teeth not in a mean way but it isn't acceptable behavior. we use to slightly pop her on the nose (i promise i would never ever "hit" my dog in a mean way, just a simple "tap" or "pop" on the nose to get her attention sometimes that's our only option) but it seemed to make her even more wilder. then i remembered hearing my groomer say never hit a dog b/c their only form of defensive/reaction is to bite. so now i'm wondering if it was me causing the problem all along?? yesterday we started time out. when she got to rowdy and i gave her a couple of chances to calm down and if it didn't work i would put her in the bathroom or my room and shut the door and ignore her for 5-10min. is this "form" of training ok? will it make it worse by shutting her up in a room for 5-10min until she understands? i've tried picking her up and holding her close and talking baby talk or a stern voice but she just wiggles like a wild woman, lol. sorry my post is so long i just want to get some feedback and make sure i'm not making the problem worse.
