This water dish with a drawing of a bone on the bottom is more in keeping with human aesthetics than a dog's point of view. We may look at that bowl and say, "A bone inside the bowl! So cute!"

Maybe we should have considered the dog's perspective.

This little pup is particularly confounded by the drawing of a delicious treat that it cannot grab. No amount of licking, pawing and biting the water is going to get that bone. And now the pup will just longingly stare into the water dish and wonder why humans are so cruel.
