They seem to have ruled out CO poisoning. The front door was open, and two other dogs were still alive. No signs of forced entry (plus, with three German shepherds, an intruder would likely have had to kill them to get at the homeowners). They seemed to just drop where they were standing.

CO poisoning would fit if the door wasn't open, though how did the other two dogs survive?

I'm not really interested in the lives of celebrities. But this one is a puzzle, and I like puzzles. So I'll probably pay a bit more attention than I normally would.
