I have raised and lived with puppies and adult dogs. I suppose I may be thinking incorrectly. I always keep my pet's food bowl full too. When they know that food is there whenever they want it, they don't scarf down everything in sight. I have friends who feed their giant dog twice a day and he opens cabinets and eats anything he can find when they're not looking; he would be too conditioned to the scarcity of food to be able to deal with an always full bowl at this point.
But obviously every dog is different. I try not to judge too harshly, it just doesn't seem ideal to me. At the same time, I have seen dogs who really like their kennels, and will go to it when it's open just to chill.
