Brindle mixed-breed terrier, 25 lbs, Milo, missing

I lost my brindle mixed-breed terrier, Milo, yesterday around 3pm. He's about 25 pounds, with a short brindle coat and a white chest patch, and he wears a red nylon collar with a brass name tag that reads Milo. We were near the State Capitol on State Street by the Empire State Plaza when he bolted toward Lark Street and disappeared toward Washington Park. He’s microchipped, so a vet or shelter could scan him. Milo is incredibly friendly once he meets you, but he’s nervous around strangers. This dog is a rescue and means the world to me—really need him back.
