She needs to feel that she is part of your family. Having a large yard is not equal to having a well exercised dog. You may see your dog dashing madly around your yard, but he is not exercising. He is doing the doggy equivalent of pacing, fidgeting, or other human forms of nervous activity. Provide your dog with fun things with which to occupy himself, such as a digging pit or special chew toys.
Dogs are social animals.
They need friends and companionship. Take your dog to the same dog park daily or weekly and let her make doggy friends. Dogs romping around and playing together tire rapidly and will sleep happily while recovering from the good, hardy play session. Until you have reeducated your dog about her barking habits, she should be confined to a place where she will cause the least disturbance. Closing the drapes will help muffle the noise for the neighbors.
