"We are deeply grateful to the concerned citizens who came the aid of our letter carrier," a USPS spokesperson told WXYZ.
The letter carrier was taken to a hospital and is in stable condition, WJBK reported. He is expected to recover, WJBK reported.
Detroit Animal Care captured the dog, whose name is Boss Hog, and ticketed its owner, WJBK reported.
"Unfortunately, attacks such as this provide the postal service an opportunity to remind dog owners that it is their responsibility to restrain their pet in order to avoid attacks against our employees while they are in performance of their duties," a USPS spokesperson told WXYZ.
