Jenny Whittall taught her Golden Retriever Lucy to bark for the cameras when she hosted the television series, Pet Friends. Now she won't stop. Stanley Coren helps her find the "off" button. Dr. Coren also helps Doug Koch tame his Cardigan Welsh Corgy Dylan who barks and lunges at other dogs on their walks. He also shows a simple way to muzzle a dog that has been hurt so that you can help him without being nipped.
