Extremely late comments are very welcome!

One of the few dogs I managed to spare was called Bear, and then I killed a dog in a later sequence and heard 'Bear!'; maybe Bear was brought on both operations, but I choose to believe that they were two different dogs and the Bear I played fetch with is fine.

I'm glad to hear you're warming to Abby! It took me a while, but I definitely got there, and I think the story's a lot stronger if you care about her.
