Not only dogs :P
I saw once a guy who was pissing in front of school, when kids were coming out of the school.

A Qatari, who was driving by, came out of his car, came to the pissing guy, took his glasses off his face, and smacked him. Then put glasses back on the pissing guy's face, and told him something in Arabic. I guess to use the toilet :D
