If so, your dog could be suffering from separation anxiety.
Dogs are social creatures.
Dogs in the wild, such as wolves, live within groups called packs. To our domestic dog, its human family is its pack. Dogs that are very attached to their human packs may become anxious when left alone and may bark, dig, chew and eliminate in the house. It is important to realize that these dogs are not being spiteful. Separation anxiety is not the only thing that will cause a dog to bark, chew, dig or eliminate in the house.
