Shadow has become self aware

Shadow is my mutt. My brother took her in to keep her from being destroyed in order to find her a good home. Ultimately, that good home ended up being HIS home. So Shadow stayed. She is a black lab of sorts. She is about the size of a lab, but she is much leaner and more muscular. She's got haunches like a greyhound and always looks like she's about to launch herself into a sprint or into the air. She looks like some kind of mix between a lab, a greyhound, and perhaps a rottweiler, but we really have no idea.

When we took her in she was very timid and shy. Before long she had usurped Molly's role as top dog in the house. Now Shadow is the alpha female. Of the two dogs, I could probably do without Shadow. She has alot of annoying "dog" habits. She sometimes craps in the basement. She humps Molly (which is really disturbing even though it's not at all sexual). She barks. She wines. She is a glutton for attention and will force her head into your hand, paw at you, and bark at you until you pet her. She is also an outside dog, so her paws are always dirty, which means all my jeans have paw prints on them because she jumps on me when I walk in the door. She is, however, very entertaining.

Here are some amusing anecdotes of Shadows talents:
She can open the cupboards. Even after my brother installed child locks on all the cupboards, Shadow figured out how to swing the doors open a couple inches and paw at the locks until the doors swing open.

She can open drawers and chewed up one of my brothers sweaters.

She has about a three foot vertical. She can bound over 4 foot chain link fences without touching the fence. When my brother put in a 5-foot picket fence that she wouldn't be able to climb (because she climbed out of our 8 foot chain link kennel), she figured out that she could jump up high enough to straddle the fence with her belly, then roll over the top.

Our storm door has a handle on it that Shadow can open at a full sprint so she can burst out of the door to bark at motorcycles that pass by.

Now I think she is becoming self-aware. She has now learned how to open our outside doors to get into the house. She turns the knob by pawing at it from the side until it unlatches and opens for her. She's like AI. She gets smarter every frickin' day. Which is entertaining, but makes her more unmanageable.

My real problem with Shadow is that she thinks she outranks me. So every now and then when she is jumping on me I put her in a headlock and pin her on the ground to show her who's boss. Rest assured, she does NOT like it when I do that. But the bitch has to know her place.
