I think that question inherently requires us to identify some subjectively fuzzy definitions for what are "why questions". It would be similar to how we have been adjusting our definition of what it means to feel pain. (particularly in the context of claims that entire animal species do not feel it, so there are no qualms about preparing them as food in ways that would be considered inhumanely cruel with others - see lobsters, crabs) Chimps recognize themselves in the mirror. So they have some theory of mind. Dogs don't, but unlike chimps, can follow pointing directions. So they have some theory of OUR mind. My dog is stubborn and doesn't follow some directions right away. I will sometimes see her pause, consider, and ignore the command. If I then remind her in a generic way that I am serious (like a stern generic "hey"), she will then come back and do the command. So it's more complex than a direct cause and effect. That also sounds like a "why" question that has gone through her head...
