New Brand - Poster Idea

As of late I have been working on a poster for the Prevent Puppy Mills united identity, and I have gotten a little stuck. To the left is what I have so far. The image will most likely be one taken from the Last Chance for animals website, seeing as how I have already spent hours trying to find a royalty free image of a sad looking dog to no avail. The description will be where the explanation for the poster will lie. It will clearly state the message and what people can do to help as well as some persuasive facts about puppy mills. The message will be the slogan adopt don’t shop, I think. If anyone has any suggestions feel free to leave a comment here or on facebook or twitter.
