Puppy food: a label checklist and three labels read
Short answer
Choose a puppy food whose label carries an AAFCO statement for growth or for all life stages, then check its calories per cup, its first ingredients and its recall history. We read three labels. All three carry such a statement, but one is not meant for large-breed growth, and the calories per cup differ by about 16 percent.
General information, not veterinary advice. If your puppy is unwell, seems in pain, or you are unsure, call your veterinarian or an emergency animal hospital. Read our medical disclaimer.
Key takeaways
- Find the AAFCO statement first. It says whether the food was tested on dogs (a feeding test) or formulated to meet the nutrient profile.
- “All life stages” foods cover growth. Check whether they include “growth of large size dogs (70 lb or more as an adult)”.
- Calories per cup ranged from 393 to 456 across the three foods, so the cups on one bag do not match another.
- We read labels and public sources. We did not feed any of these foods to dogs.
How to read a puppy food label
These five checks use the label, the maker’s published information and public guidance. None of them needs a laboratory.
- The nutritional adequacy statement. AAFCO says on its own site that it does not regulate, test, approve or certify pet food, so the statement is the maker’s claim. Look for the words “growth” or “all life stages”. The WSAVA notes that a label may say whether this was decided by life-stage feeding trials or by formulation to meet the requirements, and that “all life stages” diets are formulated for reproduction and growth.
- Calories. The WSAVA points out that calorie content is required on pet food labels in the US and helps prevent unintended overfeeding. You need it to portion the food.
- The ingredient list. Federal rules require ingredients to be listed in descending order of predominance by weight (21 CFR 501.4). The WSAVA adds that the list “gives no information on the quality of the ingredients”, so use it as one clue, not a score.
- The company. The WSAVA tool asks whether the company gives immediate contact information and who makes the food. If a maker will not answer, it advises caution about that brand.
- Recall history. Check the FDA’s recall list for the brand. See the section below.
Three puppy food labels, side by side
We picked three widely sold dry puppy foods whose makers publish full label data on their own sites. This is not a ranking and not a claim that these are the “best”. It shows what a careful label read looks like.
| Food | AAFCO statement | Protein / fat | Calcium | Calories | First ingredient | Price on maker’s site |
|---|---|---|---|---|---|---|
| Purina Pro Plan Development Puppy Chicken & Rice Formula (opens in a new tab) | Feeding test: all life stages incl. large-size growth | 28.0% min 18.0% min | 1.1% min | 456 kcal/cup 4,188 kcal/kg | Chicken | 6 lb: $19.98 ($3.33/lb) 18 lb: $52.98 ($2.94/lb) 34 lb: $74.98 ($2.21/lb) |
| Hill’s Science Diet Puppy Chicken & Brown Rice Recipe (opens in a new tab) | Feeding test: growth and reproduction | 27.8% (dry matter, average) 19% (dry matter, average) | 1.54% (dry matter, average) | 393 kcal/cup 3,747 kcal/kg | Chicken | Not shown on the page |
| Diamond Naturals Small & Medium Breed Puppy Chicken & Rice Formula (opens in a new tab) | Formulated to meet: all life stages except large-size growth | 32.0% min 22.0% min | 1.5% min | 453 kcal/cup 3,995 kcal/kg | Chicken | Not shown on the page |
Source: each maker’s own product page, read October 10, 2026. Purina and Diamond list guaranteed minimums as fed. Hill’s lists average values on a dry-matter basis, so its protein, fat and calcium are not directly comparable with the others. Prices are Purina’s own store on that date and change.
What stands out on each label
Purina Pro Plan Development Puppy Chicken & Rice
The statement is a feeding-test claim for all life stages, including growth of large-sized dogs (70 lb or more as an adult). It lists 28.0% min protein and 18.0% min fat, and chicken first, with poultry by-product meal and corn protein meal in the top four. At 456 kcal per cup it is the most energy-dense of the three. On Purina’s own store the price per pound fell from $3.33 for a 6 lb bag to $2.21 for a 34 lb bag on October 10, 2026.
Hill’s Science Diet Puppy Chicken & Brown Rice
Hill’s states that animal feeding tests substantiate complete and balanced nutrition for growing puppies and for gestating or lactating adult females. Its page shows dry-matter averages, with 27.8% protein and 19% fat, not guaranteed minimums. It lists chicken, brown rice and whole grain wheat first and 393 kcal per cup. We did not find a price on Hill’s page.
Diamond Naturals Small & Medium Breed Puppy Chicken & Rice
This food is formulated to meet the AAFCO profile for all life stages except growth of large size dogs (70 lb or more as an adult), so it is a small and medium breed food by its own label. It lists 32.0% min protein, 22.0% min fat and 1.5% min calcium, with chicken, chicken meal and white rice first, and says it contains live microorganisms. The page does not show a price.
Cost: compare calories as well as pounds
Price per pound can mislead when calories differ. On the maker’s figures, the Purina food has about 12 percent more calories per kilogram than the Hill’s food (4,188 against 3,747 kcal/kg, our calculation). A denser food means smaller portions, so a higher price per pound does not always mean a higher cost per day.
Recall history
The FDA publishes recalls and withdrawals for animal food. In the dog-related part of that list that we copied on October 10, 2026, none of the three dry foods above is named. That is not a guarantee: our copy is not complete history, and recalls change. Hill’s did have a 2019 recall of certain canned dog foods for elevated vitamin D, which was a different product line. Diamond Pet Foods was at the center of a 2012 Salmonella outbreak, which we cover on our Diamond puppy food page. Check the recall tracker and the FDA page before you buy.
What this page is not
We read labels. We did not feed these foods to dogs, test them in a laboratory or compare how puppies did on them. Your veterinarian knows your puppy’s size, health and growth rate, so ask before changing food. Read how we research.
Frequently asked questions
How much puppy food should I feed?
Start with the chart on the bag, then adjust to your puppy’s body condition. Our puppy feeding chart shows the calorie method from the Merck Veterinary Manual, which uses 3 times resting energy for puppies under 4 months and 2 times after that. It is a starting point, and the Merck manual says individual dogs may need up to 30 percent more or less.
Is grain-free puppy food better?
We found no evidence that it is. The FDA investigated a possible link between some diets, many labeled grain-free, and a heart condition called dilated cardiomyopathy. It has not reached a final conclusion and last updated its page on December 23, 2022. The FDA advises working with your veterinarian before changing your pet’s diet.
When should I switch to adult food?
It depends on breed size and your veterinarian’s advice. See our guide on how long a puppy should eat puppy food.
