My 7 year old dog has recently started grazing rather than eating all his dry food all at once. That isn't too surprising, but I noticed that he won't eat or touch his food unless someone is home.
We jokingly say that he has to make sure that the human has returned (from leaving the house) to feed him again, and that this won't be his last meal that he would need to ration.
But in all seriousness, I am slightly concerned about the behavior and am curious as to if there is a reason for this recent change in his food consumption.
