It's A Dog's Life? Or Is It A Dog's Soul?

Krystyn was in Singapore/JB on an assignment for a few days. Her two Shih Tzus Fudge and Toffee were visibly pining for her after the first two days. They sleep with her on her bed! Prince, their father on the other hand was his usual "take charge" self trying to call the shots on their food/water replenishment, dinner and sleeping times, morning toilet calls, etc., etc. He sleeps in his own basket beside my bed as he has been doing since he came to Jeannie years ago.

Since Krystyn was not around we decided to allow her two Shih Tzu to sleep in my room but with the door open so that they were free to loiter around upstairs. 

At 3.40 am on the night before Krystyn was due to return I woke up to find Fudge on the landing looking down the stairway. I took this photo with my phone, WhatsApp it to Krystyn and went back to sleep:

Then, at about 5.10 am the same night I woke up to find Prince in exactly the same spot and posture as Fudge was earlier. I reached for my phone to take a photo and when I pointed it, Prince had moved. He is canny in very inexplicable ways. The following is the shot taken seconds after I took my phone:

Notice the wispy figure between the grill and the wicker basket. I know for a fact that it was not Fudge nor Toffee because they were in my room! Sure looks like another Shih Tzu to me! Also, the dogs were behaving unusually earlier and were suddenly barking down the stairs on a few occasions.

Could it have been Chili, the departed mother of Fudge and Toffee?
