Is there anything else I can do?

[Niki]

12 days ago I was at the mall and I had my dog in my car and I opened my car door head something fall out I couldn't see anything so I went into the mall after a couple of minutes I came back to my car and my dog wasn't there I had security help me try to find him and then everyday I've been going to all the animal shelters in my area and posting ads on Facebook and stuff and I put up fliers but still no sign of my puppy he is really cute so I'm guessing someone just took him home but I want to know is there anything else I could possibly do at this point to try to get the word out?
