  The researchers found that the dogs did check significantly more often for the reward when they had not seen where it was placed. "These results show that dogs do tend to actively seek extra information when they have not seen where a reward is hidden," explains Belger.
Paper Context: This suggests that they expected the bait was hidden behind one of the fences and, additionally, they grasped that they did not have enough information about where exactly it was hidden. Therefore, dogs must have adapted their searching behavior to increase their chance of success. We showed that dogs checked more in the Unseen condition, although they were not as successful as in the Seen condition when they checked.
