How to Choose the Right Dog Food
To choose a good dog food, check three things. First, find the AAFCO nutritional adequacy statement on the label and match it to your dog’s life stage (growth for puppies, maintenance for adults, or all life stages for both). Second, favor a company that meets WSAVA nutrition standards: it employs a qualified nutritionist, owns its plants, and runs feeding trials. Third, judge the food by how your individual dog responds, stool, coat, energy, and a lean body condition, not by marketing terms like grain-free or human-grade.

The one label line that matters most: the AAFCO statement
Every complete dog food sold in the US carries an AAFCO (Association of American Feed Control Officials) nutritional adequacy statement. It is usually in small print on the back or side. It tells you two things: that the food is complete and balanced, and for which life stage. If a product has no AAFCO statement, it is not a complete diet and should only be fed under a veterinarian’s guidance.
There are two ways a food can earn the statement. A food substantiated by animal feeding trials (“Animal feeding tests using AAFCO procedures substantiate…”) is stronger evidence than one that is only formulated to meet a nutrient profile on paper. When two foods look similar, the feeding-trial food is the safer pick.
Match the food to your dog’s life stage
| Life stage | What it needs | What the label should say |
|---|---|---|
| Puppy / growth | Higher calories, protein, fat, calcium and phosphorus in a controlled ratio. Large-breed puppies need a food specifically formulated for large-breed growth to protect joints. | AAFCO statement should say "growth" or "all life stages" (and "including growth of large size dogs" for large breeds). |
| Adult / maintenance | Balanced calories to hold a lean body condition. Most healthy adult dogs do well on a quality maintenance food. | AAFCO statement should say "maintenance" or "all life stages". |
| Senior | There is no AAFCO "senior" standard. Seniors usually need adequate protein to preserve muscle, controlled calories, and sometimes joint or kidney support based on health. | Look for an "adult maintenance" food; the "senior" label is marketing, not a regulated nutrient profile. |
| All life stages | Meets the highest requirement (growth), so it is richer. Convenient for multi-dog homes, but can over-supply calories for a couch-potato adult. | AAFCO statement says "all life stages". Watch portion size for less active dogs. |
How to read a US dog food label
AAFCO nutritional adequacy statement
The single most important line. It tells you the food is "complete and balanced" and for which life stage. If it is missing, the product is not a complete diet.
"Formulated to meet" vs "feeding trials"
"Animal feeding tests using AAFCO procedures substantiate" (a real feeding trial) is stronger evidence than "formulated to meet AAFCO profiles" (lab analysis only).
Guaranteed analysis
Minimum protein and fat, maximum fiber and moisture. Useful for comparison, but does not tell you digestibility or quality on its own.
Ingredient list
Listed by weight before cooking. A named protein (chicken, beef) near the top is a good sign. By-products are not inherently bad; they include nutritious organ meats.
Calorie content (kcal/cup or /kg)
Required on US labels. Use it with your dog's weight to feed the right amount. The bag's feeding guide is a starting point, not a rule.
Manufacturer contact
A real company that will answer questions about sourcing, nutritionists, and testing is a green flag.

The WSAVA questions to ask any dog food brand
The World Small Animal Veterinary Association (WSAVA) Global Nutrition Committee recommends judging a brand by how it operates, not by its marketing. A company that answers these well is one to trust:
- Does the company employ a full-time qualified nutritionist (PhD in animal nutrition or a board-certified veterinary nutritionist, ACVN or ECVCN)?
- Who formulates the food, and what are their credentials?
- Does the company own and operate its manufacturing plants, or is production outsourced?
- What specific quality-control measures are used (ingredient testing, finished-diet testing, batch records)?
- Will the company provide the complete nutrient analysis and the calorie content of a diet on request?
- Has the diet been through AAFCO feeding trials, not just formulated to meet a profile?
What to ignore (and one real caution)
Terms like “human-grade,” “holistic,” “premium,” and “filler-free” are marketing, not regulated nutrition claims. By-products are not junk; they include nutritious organ meats. True grain allergies in dogs are uncommon.
The one real caution: the US FDA has investigated a possible link between some grain-free diets high in peas, lentils, and legumes and dilated cardiomyopathy (DCM), a serious heart disease. Unless your vet has diagnosed a specific grain allergy, a quality food with grains is the safer default. When in doubt, ask your veterinarian.
Choosing dog food: FAQ
How do I choose the right food for my dog?
Start with the AAFCO nutritional adequacy statement on the label and match it to your dog's life stage (growth for puppies, maintenance for adults, all life stages for both). Then favor a company that meets WSAVA nutrition standards: employs a qualified nutritionist, owns its plants, and runs feeding trials. Ingredient quality and your dog's individual response (stool, coat, energy, weight) matter more than marketing terms like grain-free or human-grade.
What is the AAFCO statement and why does it matter?
AAFCO (the Association of American Feed Control Officials) sets the US nutrient profiles for pet food. A product's AAFCO statement tells you two things: that it is complete and balanced, and for which life stage. A food substantiated by animal feeding trials is stronger evidence than one only formulated to meet a profile. If a product has no AAFCO statement, it is not a complete diet and should only be fed under veterinary guidance.
Is grain-free dog food better?
For most dogs, no. Grain-free is a marketing trend, not a health requirement, and true grain allergies in dogs are uncommon. The FDA has investigated a possible link between some grain-free diets (high in peas, lentils, and legumes) and dilated cardiomyopathy (DCM), a serious heart condition. Unless your vet has diagnosed a specific grain allergy, a quality food with grains is a safe default.
How much should I feed my dog?
Use the calorie content on the label with your dog's ideal weight and activity level, then adjust to keep a lean body condition (you should feel the ribs easily without a fat layer). The bag's feeding guide tends to overestimate. Omelo's free feeding calculator gives a starting daily amount, and you can scan a food to check its calories.
Do puppies need different food from adult dogs?
Yes. Puppies need a food labeled for growth or all life stages, with the higher protein, fat, and controlled calcium a growing body needs. Large-breed puppies specifically need a large-breed growth formula to slow bone growth and protect the joints. Switch to an adult maintenance food when your dog reaches maturity, around 12 months for small breeds and up to 18 to 24 months for giant breeds.
Are by-products and 'fillers' bad for dogs?
Not inherently. By-products include nutritious organ meats like liver and heart that dogs eat naturally. The word 'filler' is marketing, not a nutritional category. Judge a food by whether it meets AAFCO standards and comes from a company with strong nutrition and quality-control practices, not by fear-based label terms.
Can Omelo help me choose and track my dog's food?
Yes. Omelo lets you scan a dog food for a quick nutritional read, gives you a free feeding-amount calculator, and tracks how your dog responds over time so you can tell whether a food is actually working for your specific dog. It is free on iOS and Android.
