The United States Postal Service is putting the bite on mail service. It has nothing to do with postal agency cuts but unrestrained canines. ationwide, Springfield ranks 23rd when it comes to dog attacks on postal workers. They average about 12 dog attacks a year. Because of a handful of dogs, a neighborhood near Kearney Street at Glenstone Avenue is no longer getting mail delivered to their homes. "I get quite a bit of mail. I sent out a lot of mail. I pay all my bills manually," said Todd Magness. For the past few weeks, Magness says his mailbox has been empty.
