Veteran anchor /*Kyle Dyer*/ was petting the 85-pound Argentine Mastiff Wednesday during an interview with the owner and a fire fighter.
A day earlier, firefighters rescued the dog named Maximus -- when he fell through the ice of a frozen reservoir while chasing a coyote.
The TV station covered the rescue extensively and followed up the next day with a live interview on the TV set.
While Dyer petted Maximus under his chin -- he bared his teeth and bit her in the face.
The anchor is said to be recovering after surgery.
The owner says his dog has no history of aggression.
