This is a Frequently Barked Question.
FBQ: How do I stop my Pyrenean Mountain Dog from barking?
Clowie: All dogs bark and there can be lots of different reasons for barking. The most common reasons are anxiety, boredom, excitement, or a perceived threat. Everyone has their own ideas about how much barking is acceptable, but most of us have neighbours and have to control our urge to bark sometimes. As it’s such a big topic, I am going to concentrate on my main reason for barking and how I trained my bipeds to understand me, so that I need to bark less.
