Is she putting the dogaway back into its box? If so, because it did its job? Or did they just buy a brand new dogaway and are about to release it for the first time? It looks like she is pushing the box down on that dogaway’s head, so it leads me to believe it’s the former. But based on the instructions that the guy is reading it leads me to believe it’s the latter.
I think Mrs. got a little too anxious and instead of putting the box in the yard, tried to open it inside. She’s just now realizing her mistake but the proverbial genie can’t be put back in the bottle. The barn door is attempting to be closed with the lovecraftian horse running free. Dog-be-gone also doubles as Karen-be-gone
This was my take too. The anti-dog folks aren’t too bright.
