Oh wow. Chicho looks so much like my Luna it makes my heart ache. She was a rez dog I picked up a the Hopi Reservation in the southwest (Arizona/New Mexico region). I think she was a big mix of many generations of mixes; they all start to get that general shape and size when they're super hybrid. Wild dogs. Man, I miss her. Give Chicho some pets for me, if he's into that.
