So funny the little children:
Mami ... they killed the dog... they are so mean they are doing this only for the dramatic effect, give me a dog and when I get attached to it, it dies. I hate it.
OR
Papi... its such a bad game not even the dog can die. They don't care at all about Fallout. I hate it.
After hearing the Interview which the information is based on, it looks a lot like the Skyrim system for followers. Which would imply that followers can die while not following and fall in a coma when nearly killed in a fight as followers.
So... I think there is a big storm in a waterglass going on.
