A perfectly solid background and a bit stronger lighting would have had a more positive impact, I believe. But the idea is very original and funny, and the composition is quite good.
My evaluation method of this challenge is as follows:
1. Did you catch my eye while I was driving by? Yes.
2. If I didn't catch the text while I was driving, did you intrigue me enough to look for this billboard again? Yes.
3. Did you sell your stuff to me? Eummm... what exactly are you selling?
4. Extra thoughts: The photo is cure and funny but I have no idea what you are trying to sell.
Don't forget that people in the street do not have the time nor do they have the will to stay and think about your idea. A billboard should be very clear in it's message. Or, if it is just a teaser, it should make me wonder what's coming next.
In this photo, the message is not clear to me and the dog is too relaxed to make me wonder what's coming next.
Also your lighting (or white balance?) needs to be reviewd.
IMO your billboard did not serve it's purpose, but I will give you a 6 for a funny photo.

billboards are a science unto themselves. a lot of research has gone into determining just how much information a person can digest and retain in specific time spans. they use this information to develop formulas for determining the number of words and letters to use on billboards, as well as their sizes. they also determine the size and number of visual elements to include.
the graphics/photograph on a billboard are designed to get the point across in a moment. on the road, a driver will have less time with a billboard than a voter will give your image. this is a key element in the challenge: composing a shot that will get its point across quickly and succintly. along those lines, a strong composition will probably have few details and make strong use of negative space.
Very clever!! Nice that you left enough empty space for text, too. I think this is a great shot in every way - nothing to add in the way of constructive (or other :-) criticism.
