#9 and #8 are a little too "edgy" and it's difficult to find the dog... and difficult to identify with it once you find it. #7 and #6 are more appropriate, especially #6 with the collar serving as the end shape of the hot dog, but we are not wild about either. We have concerns about reversing the logo out of black (or any color) as it restricts the proportions/uses. Anyway, good effort, and good skills, but maybe the base concept needs to be rethought.
