Theory of mind experiment Sally Anne Test

In the original experiment, children were presented with two dolls, Sally (who has a basket) and Anne (who has a box). Sally puts a marble in her basket, and leaves the room. While Sally is away, Anne takes the marble from the basket, and hides it in her box. Finally, Sally returns to the room, and the child is asked where will Sally look for the marble? Now, I’ve adapted it for dogs. Does Pavlov have a theory of mind?
