Here’s what happened: Betsy was preparing Gene’s morning meds when she suffered a heart attack and collapsed on the bathroom floor, scattering pills. Gene discovered her there and wanted to call 911 but can’t remember the password to open his iPad so decided to seek help from the nearest neighbor. The excitement, combined with missing his morning meds, caused him to suffer a heart attack of his own and collapse in the mud room. Then the dog, unable to awaken either of his human friends, realized what he had to do: eat that entire chocolate cake that’s been sitting out on the kitchen counter since last night and then, since the bathroom closet is open, chew and tear up a few rolls of toilet paper just for old times sake. He succumbed to canine chocolate poisoning and died in the closet.

That’s not the only explanation, but it is the most logical one.
