In honor of National Dog Bite Prevention Week (May 18-24), the United States Postal Service has released the list of cities where pooches are most likely to go after mail carriers, as part of their annual report. Yes, the Post Office produces an annual report about dog attacks on postal workers, because more than 4.5 million people are bitten by dogs every year, and of those, 5,600 are USPS mail carriers. (That's about 18 attacks per day.) 

The reports breaks down dog attacks by area, and some cities are much worse than others when it comes to dog attacks. Houston, Los Angeles, and Cleveland are way out in front with the most attacks in 2013. Here at top ten worst cities to be attacked by pooches:
