No guesswork and no brand chart. This is the same calculation a vet does on paper, so you can check it.
What this means for the bowl
Harringtons Grain Free Turkey & Potato with Vegetables is one of the more calorie-dense wet dog foods we track: at 1,160 kcal per kg it has more energy than 85% 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 18 kg spayed or neutered dog needs about 979 kcal a day. That is 2 × 400 g tin of this food, but 1 ¾ × 390 g carton of Skinner's Puppy & Junior Chicken & Garden Veg and 13 × 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 3.2 times the calories of this one, which is why the wet portion looks so much bigger.
