On a side note, I do not know your dog and have not read your previous posts, but it sounds like you do not have a "dominant" dog. Just a high energy high drive dog. From what I understand truly dominant dogs are rare and require professional training almost 100% of the time. They do not do anything they do not think they should, are constantly making attempts to "climb the ladder" and can be difficult to even live with.
Don't about 'rare' but yeah you just have a bad doggie!
