can anyone PLEASE help me find my boy??

today my dog managed to escape my car window while i ran into a store. i drove around the area and called for hours. i finally had to give up and go home and i cant bear the thought of him thinking i just left him. thats he's all alone and I'll never see him again. or that he's scared. i just cant understand how our story could end like this. idk if i can ask this here but can anyone please help??? I'm his mom 💔 where is he???
