From what I can gather, it is financial issues. The woman has the GSD and a chihuahua and can only afford one. Of course I know that some will lie to avoid issues, but so far her explanations have seemed rather solid and straightforward. She hasn't avoided any questions or changed any details she's given me. I'm still going back and forth so I'll throw out a question about the GSD's health and whether she's contacted a rescue and see what comes back.
