[HisNameIsHarley]

I would keep an eye on him if his personality seems to be going flat, if his gums aren't pink and if he seems to be losing weight. Call & ask your vet though. The bag of food should tell you how much he should be getting daily. But some pups are pickier than others. Harley eats whenever he feels like it and eats differently every day. I used to have a fixed feeding time w/ a specific amount of food but he was so picky that I just started leaving a 1 cup of food in his dish all day long and if he finished it then I'd give him 1/2 a cup more and if he didn't I'd measure it out to see how much he did eat and save it for the next day. Hope this helps.
