Columbus is topping a list that may worry many mail carriers in the city.
The U.S. Postal Service says 39 letter carriers were attacked by dogs last year, making it the 9th highest city in the nation, when it comes to dog bites.
Postal employees have told 10TV that seeing a loose dog on the street can be a frightening situation if they don’t know if the animal is friend or foe.
Out of all the dog attacks last year, the USPS listed 13 zip codes in the Columbus area where dogs attacked mail carriers.
Of the 13 zip codes listed in Columbus, two had the highest counts. They were 43213 (east of Whitehall, near Broad and Hamilton Roads) and 43201 (near the Ohio State University campus near 4th and Chittenden.)
For the postal service, it's typical to see a higher concentration of problems in areas where there are more dogs.
National Dog Bite Prevention Week begins on Sunday.
