Archie is lost in Ciudad de México: can you keep an eye out?

I'm Daniel, and our dog Archie went missing on Tuesday morning near the market. Archie is brown with a white tip on the tail and very shy with strangers. We've knocked on doors, put posters up and checked the shelters. If you've seen Archie, or you have a garden camera or a shed that could be hiding Archie, please tell us through the offers on this page. We'll share contact details once we both agree, so please don't put numbers in the comments. If you find Archie, please don't chase. Speak softly and tell us where. Archie is microchipped and we'll be there within minutes. Thank you to everyone who has shared this already. Every share helps. Thank you.
