i'd think the less times you fed your dog per day , the closer you'd be to the way dogs eat naturally ........ I've read when dogs gorge themselves they require less food , they digest more efficiently ...... their stomachs are adapted to be stretched to hold something like 10% of their body weight ...... we obviously feed them like we'd want to eat , maybe they've evolved to the point where they do eat like us , i'm sure raw advocates would argue against that thought . I think gorging on kibble might be a bad idea , I do know an old guy who cooks for his dogs and feeds them all they will eat every other day . I've known him a long time , and his dogs do really well ....... I do believe when your dog gets used to their stomach being empty , occasionally having an empty gut is healthy for them ........ I've always fed my dogs and weaned pups every 12hrs , on the weekends they often just eat once a day because the morning meal may not be until 9-10am , so they don't seem to miss the evening meal .... I've never seen a healthy dog that was full , aside from when they got a bag of dog food and ate until they were so bloated it was actually scary to see .........
