What this means for the bowl
Harringtons Puppy Grain Free Tray, Chicken is one of the more calorie-dense wet dog foods we track: at 1,250 kcal per kg it has more energy than 90% of the 21 wet dog foods in our list. You will pour less of it than you might expect.
To show how much the food matters: a 7 kg puppy needs about 602 kcal a day. That is 1 ¼ × 380 g tray of this food, but 1 × 390 g carton of Skinner's Puppy & Junior Chicken & Garden Veg and 8 × 100 g pouch of Pedigree Adult Pouches Mixed Selection 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 3.0 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.
