Link is almost 7 months old and has never really been a barker. Now though when we are in the car if he thinks the car next to us is too close or there is a dog in it he will bark. He is also barking at the other dogs at Obedience but only because he wants to play with them. Rarely does he bark in the house. He will once in awhile if he thinks someone on the sidewalk is getting too close. I need help to teach him "quiet". Was wondering how you guys all do it????
