How do I increase my chances of finding my beagle?

[AmsterF]

My 3 year old girl beagle got out the back door when I hooking up my boy beagle to the tie line. She got out late evening on September 12, and she is still missing. I lost track of her in the woods when my flashlight died and she is still missing.

I have contacted all the police stations in my Boro and surrounding police stations.
I have contacted all the shelters
I have hung up signs on telephone poles
I have handed out flyers to businesses to post
I keep posting on craigslist and my facebook page.
I bought ads in the local newspapers
I have walked thru the woods for miles and miles for several hours looking for her
I am also offering a reward


She also had on her tag and is microchipped. I have not got any calls on any sightings or with any information. I dont know what else to do.

What else can I do to increase my chances of getting her back? Thanks
