I leave food for Harley out all the time, he is almost 7 months old. He became a much better eater when he started going to daycare some where he does not have access to food all the time. Although at home, it is down all the time, he will usually eat a serving in the morning, I will refill his bowl and he will leave it alone until the afternoon and eat another serving. He will rarely take more than a few nibbles though out the day. I only feed Harley dry kibble, partially because I am afraid that if I let him have any wet that is all that he will want!
