Wouldn't it mean that they're really human beings disguised as dogs? Would explain why your dog understands what you say.

Exactly.
Those dogs understand every word you say.
I can't believe that dogs are humans in disguise though.
How would they put up with that disgusting food they eat?
Even Marlon Brando at his peak would have had a hard job pretending to enjoy dog food.

I've yet to see evidence of that, especially when the figure is moving its arms and reacting to a live person. A chair or appliance isn't going to do that.

A house plant with an attitude, maybe?

Nope. The figures move around and react to people by raising their arms and squatting and so on. So no, it's not a radiator or a heat duct or a window.

I think zgmc is exactly right. It would explain everything.
Now all that needs to be done is inspect those people's houses and see if it's true.

 

[Captain Kremmen]

Inspect the houses.
Root out any fraudulent ghosts.
Send in the spooks to find the spooks.
