What this means for the bowl
Hill's Science Diet Adult Sensitive Stomach & Skin Small Bites Chicken & Barley Recipe sits in the middle of the 140 dry dog foods we track, at 393 kcal per cup.
To show how much the food matters: a 40 lb spayed or neutered dog needs about 985 kcal a day. That is 2 ½ cups of this food, but 1 ⅞ cups of Purina Pro Plan All Ages Sport Performance 30/20 Salmon & Rice and 3 ⅝ cups of Kirkland Signature Healthy Weight Chicken and Vegetable. Same dog, same day, very different scoops.
A level 8 oz measuring cup holds about 105 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.
