Wouldn't Kaylee be searching or thinking about her dog and be on alert and worried instead of sleeping?
If the dog did disappear then the possibility that prep(s) came prepared with tranquilizers (including for humans), If that is the case it does point prep to their hunting skills
Edit: May be some bait is still lying around the house and LE can find this. I am not sure how this will help as a clue in solving it
You raise a really valid point! I find it hard to believe that a sober dog could sleep through this event without barking. So either
1) someone let the dog out of the house co-incidentally before the prep(s) entered
2) the prep(s) let the dog out and he runs away
- this would indicate the prep(s) location & timing and would coincide with any potential groupchat messages about the dog missing
3) (This I got from your post) the prep(s) were highly organized and sedated the dog quietly.
4) the dog slept through the event unaware of anything
5) the dog barked incessantly and the prep(s) ignored & spared him.
It just seems odd to me that the same night that one or more unwanted and violent people enter that house that the dog either disappears or is miraculously spared…
All speculation & JMO
