Same here. My dog self regulates. I usually hear him eating kibble late at night for some reason, which is I guess when he gets hungry. My guess is fats have no self control or discipline, and give their dogs gross shit they're eating like Doritos and junk. If you gave my dog fried chicken, he would eat until he was sick too, but healthy proper dog food, or homemade healthy food he is just fine and regulates. He regularly gets fresh meat, brown rice, and vegetables. If he's getting any human food, its maybe 1 spoon of ice-cream if that.
