Ah, at least nobody is likely to take offense to a side-conversation about dogs. I think.
Lila probably had a rough life before she came to us. I know she was returned to the rescue society a few times, though the reasons for such were never volunteered (probably because they didn't want to put us off her too!). She had really bad teeth, which was expensive. She's very affectionate, and some people might not have liked how she stubbornly insists that she is, in fact, a lap dog. Hard to say.
Wolf, my first dog, was a foundling, collected outside the supermarket when I was sent out to get milk. The classic "Can we keep him, Mom?" He was a shepherd/retriever and just so intelligent and calm and well-behaved, I can't imagine why anyone would abandon him, but the state of his feet indicated that he'd walked in from being dumped in the country. Their loss, because he was a great dog.
