I'm so sad and I'm desperate!

We've lost our dog, and although this may be a little premature, he's been gone for almost 6 hours! I have looked everywhere, and I'm putting up signs, but I think that maybe like 5 people see this blog that live in my city -- so, if that's you, will you please keep an eye out for him? He's kind of scary-looking at first, but really a sweet dog. He's also pretty clumsy - so don't be worried about him having rabies or anything - he just falls down stairs a lot! Let me know if you see him! Thanks so much!
