Purina ONE True Instinct Tender Cuts in Gravy With Real Beef & Bison sits in the middle of the 18 wet dog foods we track, at 1,057 kcal per kg.
To show how much the food matters: a 40 lb spayed or neutered dog needs about 985 kcal a day. That is 2 ½ × 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 3.5 times the calories of this one, which is why the wet portion looks so much bigger.
