Hill's Science Diet Dog Food Compared: 33 Recipes by Label

Hill's Science Diet's product pages in our library publish recipe name, brand, food type, life stage, protein percentage, fat percentage, a calorie density figure, a link back to the manufacturer product page for each recipe. An AAFCO nutritional adequacy statement is published for every one of the 33 recipes in this set. 33 of 33 recipes carry a manufacturer origin address, and 3 different addresses appear across the set, the first on file being: Hill's Pet Nutrition, Inc., Topeka, Kansas, USA. A per-recipe ingredient-sourcing claim from the manufacturer is on file for all 33 recipes. A source link to the original manufacturer page is on file for 33 of the 33 recipes, which is where each figure below was read. The pages behind these 33 recipes were recorded between Jul 9, 2026 to Sep 17, 2026.

Across all 33 recipes, published protein runs 18% to 28.9% across 33 recipes with a figure published. Published fat runs 8.1% to 19.7% across 33 recipes with a figure published. Where a calorie density figure is published, it runs 2,961 kcal/kg to 3,807 kcal/kg across 26 recipes with a figure published. These are the ranges of the numbers printed on each product page, not an average, a rating, or a recommendation, and they are pulled straight from the label data we recorded for Hill's Science Diet. By life stage, the 33 recipes break down as: 23 Adult, 5 Puppy, 5 Senior.

The published ingredient lists we recorded for Hill's Science Diet run 8 to 36 ingredients long across 33 recipes. 7 of those lists were cut short on the manufacturer page and recorded as truncated, so the true count on those recipes may run longer than what is shown. The recipe count, food type, and life stage for each entry below come from the same product page as the protein, fat, and calorie figures above, so the numbers in the list match what is printed on each label as of the date we recorded it.

To compare two Hill's Science Diet recipes side by side, open the recipe pages above in separate tabs and match up the protein, fat, and calorie figures each publishes, or use our comparison tool, which pulls the same published figures into one table so the numbers line up automatically.
