In this Friday, Dec. 15, 2017 photo, Carmen Cintron, founder of Canita Sanctuary that protects abandoned animals from being euthanized, nuzzles one of her rescue dogs in Guayama, Puerto Rico. Hundreds of dogs, cats and even the occasional pet pig and fighting cock have been left at shelters as people flee hardships on the U.S. territory or stay and try to rebuild their lives after the Category 4 storm that hit three months ago.
