Have you seen my doggie?

So I have never really been a dog person, even an animal person. However, my parents do have a toy poodle and we have had for a long time now at least 10 years. I never really thought I actually liked him until yesterday. My sister called me last night to tell me that he was missing. My parents do not have a fence so when we let him out especially at night we have to stand there and watch or he wonders away. Its irritating to stand there and wait but we just havent gotten a fence up and most of the time he is good and stays close to the house. Or when he has wondered around the house before we just call him back. Apparently someone forgot to watch and well he wondered completely away. Everyone realized he was missing when they went to bed. So my dad went searching the neighborhood last night and couldn't find him, my mom and sisters walked around the house calling his name but nothing.
Well today, Thursday, they posted flyers and walked around the neighborhood hoping to find him. But no such luck. My mom said all my little brother was doing was just crying. Which makes me even more sad, I hate hearing him cry! :(
I just talked to my sister and randomly some lady saw our signs in the neighborhood and told my parents she had picked him up. However, when she took him home, he ran away from her. So he's basically lost again, in a smaller town right next to my parent's town. So they placed flyers over there and went looking for him this afternoon.
I feel so bad knowing he is walking around all by himself, no food, no water. And although its warm here, its not all that warm in MD especially at night. Let I said before I have never really been a dog person but I am really sad knowing he's out there by himself.
Plus we all worry that he going to get mad a someone picking him up and try to bit him! He's only a 7 pound toy poodle but I would hate for him to bit someone especially a child.
