I did not mention this because it was such a hectic couple of weeks for me but my puppies contracted Parvo. I was fortunate that they survived such a fatal disease. Still, we've had countless sleepless nights because of it. Anyway, since they've begun recovering, we're sticking them to an eating schedule which is 3 times a day. One time, the person in charge of feeding them forgot to feed them for lunch time. One of the little ones decided to go into the kitchen (even though they know they aren't allowed in there) and show her that their food was running late by sitting in front of her. Has your dog ever done this before simply because you forgot about the sacred schedule?
