Well, I don't agree that pictures would be even what this woman deserves. Your supervisor should tell the woman that the dog has been adopted and she cannot give out any further details. It is no longer her business how the dog is faring, since she couldn't get herself out of that situation, let alone the dogs. This sounds harsh, I know, but all of the above horror scenarios could happen. Besides, you don't know if the woman has returned to her abuser and is seeking the dog to put her back into the same situation.

The dog is adopted -- end of story!
