Cops say it's a man bites dog story -- literally.
A New Hampshire man who allegedly growled at and bit a police K-9 was arrested Friday, officials said.
Officers from the Manchester Police Dept. were called after Matthew Williams, 35, of Nashua, was reported to be "behaving erratically" in a hotel room.
Investigators said Williams wouldn't respond to their calls to leave the hotel room or answer his phone and was instead yelling, throwing items and "acting aggressive."
