I feed Lefty twice a day, each time 1/2 of the amount the dog food bag and can list as the daily amount (I have an elaborate system of how much wet and how much dry that equals, but I won't get into it). He didn't touch his breakfast this morning, and is only now beginning to eat it (5:42 p.m. EST). I usually feed him dinner at 6 p.m. In a case like this, where he chose not to eat his breakfast, should I heap even more food in his bowl, or just skip dinner?

This happens 1-2 times a week.

Thanks!
