Lost Pet: Brit

Circumstances

I was asleep in the living room with her as usual. When I woke up, noticed she wasn't in the living room anymore. I thought, "okay, a family member must have let the dogs out." And went back to sleep. When I got up, I noticed I didn't see her in the living room for a while, so I checked the other rooms of the house. She was nowhere to be found. I checked in the back yard. She wasn't there either. I walked the whole neighborhood screaming her name. I still couldn't find her. I have no idea where she is. I just want my dog back.
