I have Labs, but a neighbor has 2 GSD’s that are kept outside. They have a very small pen and access to an outbuilding that is not heated. Even in fair weather one of the dogs has a mournful cry. Sometimes it keeps neighbors awake and most think the dog is injured or has other health issues. I talked to the owner. He claims the dog just needs to adjust to its new home. I think the dog is yearning to socialize with its humans. Any advice? I would hate to have the Sheriff or Humane Society intervene.
