The best dog food is a complete and balanced diet suited to your dog’s life stage—not a universally winning brand or an ingredient list that sounds appealing. Compare the food’s adequacy statement, calorie information, and the manufacturer’s nutrition expertise and quality-control practices; for a diet tailored to your individual dog, ask your veterinarian.
“Best” depends on whether a food is nutritionally adequate for the dog it is intended to feed and whether the maker can explain how it formulates and controls the product. The World Small Animal Veterinary Association (WSAVA) offers questions owners can use to assess commercial foods, but it does not certify or endorse a particular brand. Its guidance is a way to screen products—not a brand ranking or a substitute for veterinary advice.

What should you look for first when choosing dog food?
First, look for a food that is labeled complete and balanced for your dog’s species and life stage. A product intended for intermittent or complementary feeding is not a substitute for a complete everyday diet.

Find the nutritional adequacy statement, rather than relying only on large claims on the front of the package. In the United States, the statement identifies whether the food is complete and balanced for a stated life stage or is intended for intermittent feeding, and describes the basis for the adequacy claim. Label rules differ by country, so the exact wording and required details may vary.
Then confirm that the stated life stage fits your dog. A food labeled for a different life stage should not be treated as interchangeable simply because the packaging or ingredient list seems similar. If the label is unclear, ask the manufacturer to explain the intended use and adequacy statement. The WSAVA pet-food selection guide sets out questions to help owners make this assessment.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →What does “complete and balanced” mean on a dog-food label?
It means the food is presented as a complete diet for the life stage shown, rather than a product intended only as a supplement, treat, or occasional component of meals. Read the full adequacy statement to understand what the claim covers and how it was established.
WSAVA’s guide describes two bases for an adequacy claim: a food may be formulated to meet a nutrient profile, or it may carry an animal feeding-trial statement. These are different ways of substantiating adequacy. Neither statement promises that every individual dog will thrive on that food, nor does either remove the need to choose an appropriate diet for the individual animal.
Do not confuse a complete everyday food with one labeled for “intermittent,” “supplemental,” or “complementary” feeding. Those terms signal a different intended use. If you are comparing products, copy the exact adequacy language from each label and compare the life stage and basis for the claim—not just the product name or front-of-pack headline.
How to read the statement in the United States
On a U.S. label, look for the statement that identifies the nutritional purpose and life stage, along with wording about whether the food was formulated to meet a nutrient profile or supported by feeding trials. The statement is more informative than a logo, a picture of meat, or a claim such as “natural.” Keep a photograph of the complete statement when asking a veterinarian or manufacturer about a product, because a shortened front-label claim may omit important qualifications.
Outside the United States, the required format and terminology can be different. That does not make the label unusable; it means you should ask the maker what standard the adequacy statement refers to and whether the food is intended as a complete diet or only as a complementary product. A retailer’s product description is not a substitute for the manufacturer’s official label.
Should you choose dog food by its ingredient list?
No. Ingredient names alone do not establish nutritional quality, digestibility, or how well nutrients are available to the dog. An ingredient list is not a reliable quality score.

Marketing terms such as “premium” and “holistic” also have little practical value for assessing nutritional adequacy, according to WSAVA. Such words may make a product sound distinctive, but they do not answer the central questions: Is it a complete diet for the right life stage? How was the adequacy claim established? Can the company explain its formulation and quality controls?
Use the ingredient list as one piece of product information, not as a shortcut around those questions. A long list, a familiar ingredient name, or language that sounds natural does not by itself show how the finished food compares nutritionally. If a company’s marketing relies on ingredient claims but it cannot answer basic questions about the food’s formulation and analysis, that is a reason to seek clarification.
Common ingredient-list pitfalls
- Ranking ingredients as a quality contest. The order and names do not reveal the complete nutrient profile or the digestibility of the finished food.
- Treating a single ingredient as proof of adequacy. No one ingredient establishes that a diet supplies everything required for its stated life stage.
- Confusing a marketing adjective with a standard. “Premium” and “holistic” do not answer who formulated the food or how it was tested.
- Ignoring intended use. A product with appealing ingredients may still be labeled only for intermittent or complementary feeding.
When an ingredient list raises questions, use it as a prompt to contact the company, not as a reason to make a nutritional judgment from names alone.
How can you assess the company that makes the food?
Ask who formulates the food, what relevant nutrition qualifications the company employs, and how it controls ingredients and finished products. The company should be able to answer questions about its process and provide useful nutritional information.
WSAVA identifies a PhD in animal nutrition or relevant board certification as appropriate qualifications for a nutritionist. Ask whether the company has qualified nutrition staff and who is responsible for formulating the specific food you are considering. A vague appeal to a brand’s reputation is not as informative as a clear answer about expertise and responsibility.
Also ask how the company validates ingredients, analyzes finished products for nutrient content, and manages safety controls. These are questions about the maker’s process, not guarantees that a product will suit every dog. If information is missing from the package or website, contact the company and ask for a typical nutrient analysis and an explanation of its quality-control practices. A company’s ability and willingness to respond are relevant parts of the comparison.
Questions worth sending to a manufacturer
A short, specific message is more useful than asking whether a food is simply “good.” Ask:
- Who formulated this particular product, and what nutrition credentials do they hold?
- Is the food complete and balanced for a stated life stage, or is it intended for intermittent, supplemental, or complementary feeding?
- Was adequacy established by formulation to a nutrient profile, an animal feeding trial, or another method described on the label?
- What is the calorie content, and can you provide a typical nutrient analysis for the finished food?
- How are incoming ingredients validated and how are finished batches analyzed?
- What safety controls are used, and whom should an owner contact with follow-up questions?
Save the response with the product name and lot or package information. If the answer is incomplete, evasive, or inconsistent with the label, record the missing item as unknown instead of filling the gap with an assumption.

Research can be another consideration: WSAVA suggests asking whether the company conducts nutrition studies and whether they are published in peer-reviewed journals. But companies are not required to conduct or sponsor nutrition research to sell food. Research should not be treated as a substitute for a suitable adequacy statement, qualified formulation, or sound quality controls.
Why do calories and feeding directions matter?
Calorie information helps you understand how much energy the food provides and can help prevent unintended overfeeding. Check whether calories are given in a usable form and whether the package provides feeding guidance.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
WSAVA recommends checking calorie content, but label requirements vary across countries. If the calorie information is missing or unclear, ask the manufacturer rather than trying to infer it from the ingredient list. Feeding directions are useful information, not a reason to ignore your dog’s individual needs; a veterinarian can help tailor nutrition planning.
When comparing two products, note calorie information and feeding guidance for both. A comparison based only on serving size can be misleading if the foods differ in calories per serving. Keep the comparison tied to what the label and manufacturer actually disclose, and ask for clarification where a necessary figure is unavailable.
Do not assume that a larger scoop, a smaller can, or a different moisture level makes one food more or less nutritious. The practical question is whether you can determine the calorie information and use the feeding guidance responsibly. If you change products, keep the old and new label details together so your veterinarian can see exactly what changed.
How do you compare two dog foods side by side?
Use the same questions for each product so that packaging and marketing do not dominate the decision. This checklist reflects WSAVA’s selection guidance; it screens for useful evidence but does not rank brands.

- Read the basis for adequacy. Does the statement say the food was formulated to meet a nutrient profile or that adequacy was established through an animal feeding trial? Record the actual wording.
- Find calories and feeding information. Can you determine the food’s calorie content and follow its feeding guidance? If information is unavailable, ask the company; do not guess.
- Ask who formulates it. Does the maker identify the responsible nutrition professional and relevant qualifications, such as a PhD in animal nutrition or applicable board certification?
- Ask about controls and analysis. Can the company explain ingredient validation, finished-product nutrient analysis, and safety controls? Can it provide a typical nutrient analysis?
- Consider research in context. Does the company conduct nutrition studies, and are they peer-reviewed? Treat this as one consideration, not a replacement for the other checks.
- Bring individual needs to your veterinarian. If you are choosing for a particular dog, ask whether the candidate food fits that dog’s needs. General label criteria cannot settle every individual diet question.
A simple comparison sheet can keep the decision grounded: write down each product’s intended life stage, exact adequacy wording, calorie information, and the company’s answers about formulation and controls. If a company cannot provide information, note that as unknown rather than assuming the answer is favorable. When two products both appear to meet the basic criteria, individual suitability is a reason to involve your veterinarian, not to declare one universally superior.
A practical decision sequence
Start with the products you can obtain consistently and whose labels you can verify. Eliminate anything that is not intended as a complete diet for the relevant life stage unless your veterinarian has specifically directed its use as a complementary product. Next, set aside foods for which the adequacy statement, calorie information, or manufacturer contact details cannot be confirmed. Then compare the remaining companies’ answers about formulation, nutrient analysis, ingredient validation, and safety controls. Only after those checks should you consider secondary information such as published studies or preferences about ingredients.

This sequence prevents a striking package or a persuasive online review from deciding the issue before the basic requirements are known. It also creates a record you can revisit if the formula, label, or manufacturer’s answers change.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When should a veterinarian help choose your dog’s food?
Ask your veterinarian when you need a diet tailored to your individual dog or are unsure whether a particular food fits. WSAVA identifies the veterinarian as the best person to advise on an individual pet’s diet.
The general screening questions in this guide cannot account for every dog’s circumstances. They help you identify what a product claims and what its maker can substantiate; they do not prescribe a diet for an individual animal. Bring the packaging or product details, including the adequacy statement and calorie information, so the conversation can focus on the food you are considering.
A veterinary appointment is also useful when two foods pass the label checks but you still cannot decide, when a dog’s current diet is not meeting expectations, or when you are considering a product labeled for supplemental or intermittent use. The veterinarian can interpret the label in the context of the individual dog instead of treating a general checklist as a diagnosis or prescription.
The WSAVA Global Nutrition Committee puts the point directly in its FAQ: “Your veterinarian is the best person to ask about the best diet for your pet, and in the following links you can find some guidance to choose a commercial brand of pet food to ensure that the food is safe and nutritionally adequate.” This is guidance from the committee, not an endorsement of any particular product.
What should you do when a food’s information is incomplete?
Do not fill missing information with assumptions. Check the official package, then contact the manufacturer for the adequacy basis, calories, typical nutrient analysis, formulation responsibility, and quality-control details. Label requirements differ by country, so a missing item may reflect local rules, but you still need enough information to make a responsible comparison.

This is a selection framework, not a list of ranked foods. The criteria follow the WSAVA Global Nutrition Committee’s Frequently Asked Questions & Myths and its Global Nutrition Guidelines: verify complete-and-balanced status and intended life stage; understand the basis for the adequacy claim; check calories; assess the maker’s nutrition expertise, formulation, quality controls, and transparency; and treat research as one consideration. The guidance does not establish a universal best brand or formula.

Frequently Asked Questions
Does WSAVA approve or certify dog-food brands?
No. WSAVA provides questions and guidance for evaluating pet foods; its selection materials do not amount to approval or certification of a particular brand. A company’s claim that a food meets a nutritional standard should be assessed from the product’s own adequacy statement and supporting information.

One-click scans. No signup required.
What should I do if the label does not list calories?
Ask the manufacturer for the calorie content and a typical nutrient analysis. Label requirements differ by country, so missing information does not by itself explain why it is absent; get the figure directly rather than estimating from the ingredients.
Does a feeding-trial statement mean a food is best for every dog?
No. WSAVA describes feeding trials as one basis for an adequacy claim, alongside formulation to a nutrient profile, but neither basis guarantees the same outcome for every individual dog. Suitability for a particular pet is a question to discuss with a veterinarian.
Is a food with published nutrition research automatically a better choice?
Not automatically. WSAVA treats research, including whether studies are peer-reviewed, as one useful consideration, and notes that companies are not required to conduct or sponsor nutrition research to sell food. Research does not replace checking intended life stage, adequacy, formulation expertise, and quality controls.
Can I feed a product labeled intermittent or complementary as my dog’s only food?
Those labels indicate a different intended use from a complete everyday diet. Do not substitute such a product for a complete and balanced food unless your veterinarian has given specific instructions for its use.
The Bottom Line
Choose a complete and balanced food for your dog’s life stage, verify how the adequacy claim was established, check calories, and question the maker about qualified formulation and quality controls. Treat ingredient lists, “premium” language, and published research as limited context—not proof by themselves. For an individual recommendation, consult your veterinarian.
