There is no reason why a dog should eat at the same time every day, nor should they ALWAYS eat once a day or ALWAYS twice. Mine do very well on unpredictability and change!
Since the weather has gotten colder I am back to feeding twice a day, one time in morning (any time) and another in the evening (whatever works for me.) The dogs don't beg at a certain hour and are quite pleased to get their meals when they get them.
