I don't know what wierd is! Wish we did have better understanding of how things all work together in this area of care.
I don't have a routine. That is my routine. Usually the dogs get food when they work for it. I have come to believe this increases the value and enjoyment of food, especially in a working breed, but probably in most dogs. The training schedule is not routine so it can happen at different times throughout the day. If there is no training or not enough, then additional food is given in bowl though its not routine.
Often there is a day of fasting or near fasting, but no pattern to that either. Mother Nature is unpredictable and so am I. I watched a show where a dog was not eating well. Once it was put into a scenario of being active and of having to work for food, the food drive problem resolved itself.
Alternatively, I have heard a routine is good and that may be so.
