The maths, with your numbers
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
Purina ONE +Plus Healthy Weight Tender Cuts In Gravy Lamb & Brown Rice Entrée is on the lighter side: at 966 kcal per kg it has less energy than 71% of the 18 wet dog foods in our list, so the bowl will look fuller for the same calories.
To show how much the food matters: a 40 lb spayed or neutered dog needs about 985 kcal a day. That is 2 ¾ × 13 oz can of this food, but 9 ¼ × 3 oz can of Purina Beneful IncrediBites Small Breed Loaf with Real Chicken and 4 ½ × 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 3.8 times the calories of this one, which is why the wet portion looks so much bigger.
This is a weight-control recipe. If your dog needs to slim down, tick “Needs to lose weight” in the calculator and enter the target weight your vet gave you; the portion is then worked out for the target, not the current weight.
