Perhaps make the two portions bigger if you feel compelled to feed him X amount everyday.
I wonder if the morning meal is the particular meal where a dog's hunger might be least present at times. With my dogs over the years, the least amount of energy they expend is after their evening meal, perhaps making the ensuing morning meal not as necessary in their eyes....????????
Perhaps. I'll try that, he typically wont eat more than 1.5cups per meal though. I'll see how it goes at lunch today. I wouldn't be concerned by it if he were growing and developing like he should be.
