I check this thread over and over hoping for good news.

Sending prayers you'll find her and that God is watching over Delilah until she comes home.
See Teri88's post? Well....a year ago...we met up with Teri for her to pick up Maddie in Ohio. Maddie escaped and took off in a panic run. We spent hours looking for her....made fliers, handed those out, posted them, called the radio station, everything you can imagine. As evening approached there was a phone call with a Maddie sighting....much further than we ever imagined Maddie would travel....LIKE 2 MILES. A group went that night...no Maddie, the next morning...two of us went again...no Maddie...later on Teri and Megan went...no Maddie....finally Maddie's original owner was able to come...and low and behold...out from the brush...comes Maddie.
The point of that story...is just how far they will travel if scared...along with the fact...Maddie was there...just hiding from us.
Keep on looking...is there a squeaky toy Delilah likes? Or a phrase...like treat? Mine will come to either of those...
I wish I had more suggestions...keeping you both in my prayers.
