Branding...

So here are a few ideas about my branding/logo. Since my concept is interlocking relationships, dealing with both the dog as well as the owner having to depend on each other. The name of my store reflects words that owners say and then the dog responds by obeying (or at else most of the time). This having to do both the dog and the owner, which is what the goal of my store is about. Having 3 S's in my store name, i tried to emphasize that as well as my concept of interlocking relationships. I am still working on my color scheme because i thought of my space to be black and white with one accent color. Dogs only see black, white and blue hues, by doing this the colors of the products will stand out more (but i am still considering this thought). Please help me narrow my designs, with your feedback...any favorites.
