What this means for the bowl
Rachael Ray Nutrish Puppy Real Chicken & Brown Rice Recipe sits in the middle of the 140 dry dog foods we track, at 390 kcal per cup.
To show how much the food matters: a 15 lb puppy needs about 590 kcal a day. That is 1 ½ cups of this food, but 1 ⅛ cups of Purina Pro Plan All Ages Sport Performance 30/20 Salmon & Rice and 2 ⅛ cups of Kirkland Signature Healthy Weight Chicken and Vegetable. Same dog, same day, very different scoops.
A level 8 oz measuring cup holds about 106 g of this kibble. If you have kitchen scales, weighing is more accurate than scooping, because a heaped cup holds noticeably more than a level one.
Puppies need about three times their resting energy until 4 months, then about twice. Weigh weekly, because the portion changes as they grow.
