Generally speaking, what's the nutritional difference of feeding a dog two times daily (every 12 hours) versus three times daily (every 8 hours) when the total amount is the same? (Assuming it's a healthy dog with the correct total daily amount of quality food being fed.)
Dogs in their natural habitat (without owners), would feed once a day.
However, it depends on a dog's appetite.
You can feed her three times a day if she has an appetite.
All the best.
