STILL MISSING. REWARD FOR LOST DOG!!!!!

!!! STILL MISSING !!! 150 REWARD !!!
INDY went missing on the evening of 1/7 near ROCKBRIDGE & FIVE FORKS TRICKUM ROADS in LILBURN / STONE MOUNTAIN.
He weighs 35 lbs and has the build of a greyhound. He is not a small dog! He is the size of a lab with a thinner body! We have had multiple calls for pomeranian size dogs... It breaks our heart every time we get somewhere thinking it's our dog and it isn't. Please be aware of his size. When standing, he is about hip height or lower. His coat is black with a white patch on his chest. He is microchipped but was not wearing his collar at the time. Indy is a rescue and very timid, will probably not come when called. PLEASE CALL 404 -578 -3156 IF YOU SPOT HIM. If you see him, please do not let him out of your sight, please give us a chance to arrive... Indy has severe allergies and needs our attention or he could become seriously ill. Please keep your eye out for my dog... we miss him so much...
We have posted in vet clinics, parks, public places, contacted all the pounds and humane societies (we regularly check up with them), gone door to door, and posted over 500 fliers in our area. We have exhausted every avenue we know to exhaust to find our dog. If anyone has any ideas for further things we can do please let me know... It's been almost a month. 
SHARE THIS POST, PLEASE. "Liking" the post does not get it out to more eyes. In fact I think liking is bizarre, considering there's nothing to like about missing pups. Please help me find my dog. The more people who see it, the sooner Indy comes home!!!
