Dorm director teaches dog to bark in whisper

GREENVILLE, Ill. -- A resident director who lives in a dorm at a college in Southern Illinois taught his dog to bark in a whisper. Brian Gertler lives in an apartment with his wife and 1-year-old dog, Dudley, in a freshman dorm at Greenville University. Gertler found Dudley's excited barking when they played together woke up students at night. Gertler said he slowly trained the dog to bark in a whisper. That means they can play in a much quieter way...
