I guess I'm lucky, my Bentley rarely barks, and if he does it's not excessive. He's just alerting us to something outside. Though he has started barking and growling to wake me up from a nights sleep or even a nap, so not sure how to combat that, but it's not too bad. I'll be adopting a puppy sometime next year probably and will probably have to learn how to stop excessive barking. Bentley used to whine a lot when he was in his expen and we worked with him to get him to stop it. I don't remember what I did but it seems to have stopped the barking problem that Bentley was developing. lol I hope I can remember what we did before I get my new female next year.
Good luck all!
