What this means for the bowl
Purina Pro Plan Puppy Sensitive Skin & Stomach Salmon & Rice Entrée Classic sits in the middle of the 18 wet dog foods we track, at 985 kcal per kg.
To show how much the food matters: a 15 lb puppy needs about 590 kcal a day. That is 1 ½ × 13 oz can of this food, but 5 ½ × 3 oz can of Purina Beneful IncrediBites Small Breed Loaf with Real Chicken and 2 ¾ × 9.5 oz carton of Purina Beneful Freshly Prepared Stews Chicken Dinner with Carrots and Rice in Gravy. Same dog, same day, very different bowls.
Wet food is mostly water. Gram for gram, the average dry dog food in our list has about 3.7 times the calories of this one, which is why the wet portion looks so much bigger.
Puppies need about three times their resting energy until 4 months, then about twice. Weigh weekly, because the portion changes as they grow.
