Please help us find Biscuit, our spaniel, last seen in Cartagena

I'm Rodrigo, and our spaniel Biscuit went missing on Thursday night near the river path. Biscuit is black with one white paw and very shy with strangers. We've knocked on doors, put posters up and checked the shelters. If you've seen Biscuit, or you have a garden camera or a shed that could be hiding Biscuit, 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 Biscuit, please don't chase. Speak softly and tell us where. Biscuit is microchipped and we'll be there within minutes. Thank you to everyone who has shared this already. Every share helps. Thank you.
