Yes, you may have, but that was when there were still thousands of people there. Now that things have calmed down and the place has cleared out, you have a good chance of finding your pup. Posting the more will not help at this point. If someone has picked him up, they would have reached out and seen the post by now. I still recommend going back out and spending a day or so looking around the entrance road, little dunes, and camp area. Trust us, we see it happen every holiday weekend. He's still out there.
