As I am walking down a busy street in central Zagreb, I come upon a big dog chained to a railing next to a grocery store. Its owner must be within. Sitting peacefully and paying no attention to passers by, the dog is sporting a huge erection. Shooting straight up, its penis is as red as red can be. Having just come out of its protective skin, it is moist, too. Three women in their teens walking right behind me start giggling their heads off as soon as they spot it. The penis. They seem to know what is on the dog’s mind quite exactly.
