Fresa, 5, stands inside the dog shelter “Santuario Milagros Caninos” on the outskirts of Mexico City August 29 2014. Fresa underwent reconstructive surgery after her previous owners hacked off half of her snout with a sharp object, possibly a machete, according to surgeon Jesus Paredes. After neighbours found Fresa wandering on the streets, they handed her over to a shelter where Paredes performed a three-hours intervention to enable her to breathe again through her nostrils, to remove her protruding jaw and reconstruct the lips with flaps of skin and mucous.
