Researchers at the Eötvös Loránd University (ELTE) Department of Ethology, Budapest investigated if companion pigs and dogs would show their owners the location of a food reward that was out of their reach (but reachable for their owner). They found that if the owner was in the room, pigs paid her/him as much attention as dogs did. However, when the reward was also present in the room, only dogs tried to direct the attention of the owner to the reward location.
