Celo poses for a picture at the Famproa dogs shelter in Los Teques, Venezuela August 18, 2016. Celo (on heat) was given her name because she was left tied outside the shelter in the middle of her fertile stage. "When the volunteers arrived, the place was a mess. All the males, although they were castrated, were going crazy," said Maria Silva who takes care of dogs at the shelter. REUTERS/Carlos Garcia Rawlins SEARCH "DOG LIFE" FOR THIS STORY.
