LOST mini schnauzer!

My dear dog has gotten out Monday night, April 23, 2012. He is about 10 years old, super nice! Lost in West Covina,California. His name is Simon, he has his 3-4 front bottom teeth out, he's gray and white, and he has a collar on no tag though. Please, help me find my dog. If found please call (626) 332-5841, or e-mail huskeyhannah@yahoo.com.
