Lost dog! DALLAS TEXAS

Hello! I know this is a long shot but please please help me find my baby! Even if it's a repost on facebook or Instagram but I am desperate. It's my 6year old spayed female chihuahua. She must of gotten out my gate today around 3pm when I left to the grocery store. She is tiny so I'm scared someone picked her up and kept her as I've been searching non stop around my neighborhood. She is not kid friendly and has terrible separation anxiety. She is my toddlers best friend and my bestfriend too. I can offer a reward of anyone is kind enough to return her no questions asked. I'm pregnant and I'm trying so hard not to work myself up for the sake of my pregnancy and my son. I'm just so lost. Please help me!!
