My take on it is that the puppy got hurt as a result of an accident. Little pups have a tendency to get stepped on. It's no one's fault. However, the important thing is that a good home is found for this pup and it doesn't matter who takes that responsibility on. If FA & kids don't want the puppy, they shouldn't have to keep it, however, I think they're more responsible than the X so maybe it would be in everyone's best interest if they made sure the puppy has a good home with someone else. Not sure if that's what's going on or not......
Anyway, this is really not "our" issue as FA has not asked for advice on this subject and Trip seems to be taking the brunt of the negativity. Sorry, Trip.
