I think that health education instilled in us from a young age has deeply ingrained the idea: "Regular and measured eating can maintain physical health." The same principle, when applied to our beloved dogs, should hold true as well. Most pet owners tend to feed their dogs at fixed times, usually scheduled before the owner's family meals. On one hand, it's out of consideration for not letting the dog go hungry; on the other hand, it avoids the dog causing a disturbance while the family enjoys their meal peacefully. However, this practice might actually be the reason why dogs become "self-centered."
