Complete Guide to Choosing Dog Food

The best dog food is one that is complete and balanced for your dog’s life stage, fits their health needs, supports a healthy body condition, and is practical for you to feed consistently.

There is no single food type that is best for every dog. Kibble, wet food, fresh cooked food, homemade meals, raw diets, and freeze-dried foods can all vary widely in quality, calorie density, safety, cost, and nutritional completeness.

Choosing dog food should involve more than checking the first ingredient or following marketing terms such as “premium,” “natural,” “holistic,” or “human-grade.” The nutritional adequacy statement, life-stage claim, calorie content, feeding directions, manufacturer transparency, and your dog’s response are all important.

This guide explains the major dog-food types, how to compare commercial and homemade diets, how to read a dog-food label, what AAFCO statements mean, the role of carbohydrates, and how to choose a suitable diet for your dog.

What Makes a Good Dog Food?

A suitable dog food should:

• Provide complete and balanced nutrition for the correct life stage
• Supply an appropriate number of calories
• Be safe and consistently manufactured
• Be digestible for the individual dog
• Support healthy weight and muscle condition
• Fit any medical or dietary restrictions
• Be affordable and practical enough to feed consistently
• Be accepted by the dog

The appearance of the packaging, popularity of a diet trend, and position of a single ingredient do not determine whether the finished food is appropriate.

Every Dog Has Different Needs

The best choice depends on factors such as:

• Age and life stage
• Expected adult size
• Current body weight and body condition
• Activity level
• Breed-related considerations
• Pregnancy or nursing
• Food allergies or intolerances
• Digestive sensitivity
• Kidney, heart, liver, or pancreatic disease
• Dental health
• Medication use

Main Types of Dog Food

Dog food is available in several formats. Each has potential advantages and drawbacks.

Kibble or Dry Dog Food

Kibble is the most widely used dog-food format. It consists of cooked, dried pieces formulated to provide a specific nutrient and calorie profile.

Benefits of Kibble

• Easy to store
• Simple to measure
• Usually more economical than wet or fresh food
• Available in many life-stage and therapeutic formulas
• Convenient for feeding toys and training
• Longer shelf life than many high-moisture foods

Possible Drawbacks of Kibble

• Contains relatively little moisture
• May be less appealing to picky dogs
• Calorie density can make overfeeding easy
• Quality and formulation vary between products
• Storage after opening affects freshness

Kibble does not automatically clean a dog’s teeth. Standard dry food may provide some abrasion, but it does not replace brushing or professional dental care.

How to Store Kibble

• Keep the food in its original bag when possible.
• Place the bag inside a clean, sealed container.
• Store it in a cool, dry location.
• Close the bag tightly after each use.
• Do not mix new food into an unwashed container holding old crumbs.
• Check the best-before date and product condition.

Wet or Canned Dog Food

Wet food is sold in cans, trays, or pouches and contains substantially more moisture than kibble.

Benefits of Wet Food

• Higher moisture content
• Strong aroma and palatability
• Soft texture for dogs with chewing difficulties
• May help some dogs feel satisfied with a larger food volume
• Available in complete diets and veterinary formulas

Possible Drawbacks of Wet Food

• Often more expensive per calorie
• Requires refrigeration after opening
• Cannot be left out for long periods
• Creates more packaging waste
• May be less convenient for travel or food-dispensing toys

Confirm that the product is labeled as complete and balanced. Some canned foods are toppers or supplemental products rather than full diets.

Fresh Cooked Dog Food

Fresh commercial diets are gently cooked and usually sold refrigerated or frozen. They may resemble homemade meals but are manufactured and packaged commercially.

Potential Benefits

• High moisture
• Strong palatability
• Soft texture
• Convenient compared with cooking from scratch
• May use recognizable pieces or ground ingredients

Possible Drawbacks

• Higher cost
• Refrigeration or freezing requirements
• Shorter usable life after opening
• Calorie content may be easy to misjudge
• Not every product is complete and balanced

Review the nutritional adequacy statement rather than assuming that fresh appearance means superior nutrition.

Raw Dog Food

Raw diets may contain uncooked meat, organs, bones, eggs, fruits, vegetables, and supplements.

Raw food is not automatically more nutritious, digestible, or natural for every dog. Major concerns include:

• Salmonella, Campylobacter, E. coli, and other pathogens
• Parasites
• Cross-contamination in the home
• Nutrient deficiencies or excesses
• Broken teeth
• Choking
• Intestinal blockage or injury from bones

For a detailed review, read our guide to raw diets for dogs.

Freeze-Dried Dog Food

Freeze-dried food is made by freezing ingredients and removing moisture under low pressure. It is lightweight and shelf-stable before opening.

Freeze-dried products may be complete meals, toppers, mixers, or treats. Check the label carefully.

Potential Benefits

• Convenient storage
• Lightweight for travel
• High palatability
• Simple portioning
• Can often be rehydrated

Possible Drawbacks

• Often expensive
• Very low moisture unless water is added
• May be calorie-dense
• Freeze-drying does not guarantee sterility
• Some products are not complete diets

Homemade Dog Food

Homemade dog food gives owners control over ingredients and preparation. However, creating a nutritionally complete diet is more difficult than combining meat, rice, and vegetables.

Potential Benefits

• Ingredient control
• Customization for selected medical needs
• Useful for some elimination or therapeutic diets
• High palatability
• Ability to avoid a specific ingredient

Risks and Drawbacks

• Deficiencies in calcium, vitamins, minerals, or essential fatty acids
• Incorrect calcium-to-phosphorus balance
• Excess calories or fat
• Time-consuming preparation
• Need for careful storage and food safety
• Recipe drift when ingredients are substituted
• Difficulty maintaining consistency

Homemade diets should be formulated by a board-certified veterinary nutritionist or another appropriately qualified veterinary professional.

Online recipes and recipes based only on meat, rice, and vegetables are often nutritionally incomplete.

Commercial vs. Homemade Dog Food

Commercial food is not automatically low quality, and homemade food is not automatically healthier. The quality of either depends on formulation, safety, ingredients, and suitability for the dog.

How to Read Dog Food Labels

A dog-food label contains more useful information than the front of the package. Important sections include:

• Product name
• Net weight
• Ingredient list
• Guaranteed analysis
• Nutritional adequacy statement
• Life-stage claim
• Calorie statement
• Feeding directions
• Manufacturer or distributor information

Do Not Rely Only on Marketing Terms

Words such as the following may have limited value when used without additional context:

• Premium
• Super-premium
• Holistic
• Gourmet
• Ancestral
• Superfood
• Human-grade
• Natural

Evaluate the full label, manufacturer, and nutritional adequacy instead.

What Does AAFCO Mean?

AAFCO stands for the Association of American Feed Control Officials.

AAFCO develops model regulations, ingredient definitions, nutrient profiles, labeling guidance, and feeding-test protocols used by many regulators and pet-food manufacturers.

AAFCO does not approve, certify, test, or endorse individual dog foods.

There is no official category of “AAFCO-approved dog food.” More accurate wording includes:

• Formulated to meet AAFCO nutrient profiles
• Nutritional adequacy substantiated through AAFCO feeding procedures
• Complete and balanced for the stated life stage

How Can a Food Meet AAFCO Nutritional Standards?

Formulation Method

The recipe is formulated to meet the nutrient levels in an applicable AAFCO Dog Food Nutrient Profile.

Feeding-Test Method

The food is evaluated using an applicable AAFCO feeding protocol.

Product-Family Substantiation

In some situations, nutritional adequacy may be supported through a qualifying product-family relationship.

The label wording should explain how adequacy was substantiated.

What Does “Complete and Balanced” Mean?

A complete and balanced food is intended to provide all essential nutrients in appropriate proportions for the life stage shown on the label when fed according to directions.

The nutritional adequacy statement may indicate that the food is intended for:

• Growth and reproduction
• Adult maintenance
• All life stages
• Intermittent or supplemental feeding only

Foods marked for intermittent or supplemental feeding are generally not intended to be the dog’s sole everyday diet unless directed by a veterinarian.

Choosing Food by Life Stage

Puppies

Puppies require food appropriate for growth. Developing dogs have different calorie, protein, mineral, and vitamin needs from adults.

Large-breed puppies require particular attention to calorie and mineral balance. Look for a statement showing that the food is appropriate for the growth of large-size dogs when applicable.

Adult Dogs

Adult-maintenance food is intended for mature dogs that are no longer growing and are not pregnant or nursing.

All-Life-Stages Food

All-life-stages foods meet requirements that include growth and reproduction. They may be more calorie-dense than some sedentary adult or senior dogs require.

Senior Dogs

“Senior” is not one universal nutritional category. Older dogs may require different calorie levels, protein amounts, textures, or therapeutic diets depending on their health.

Pregnant and Nursing Dogs

Pregnant and nursing dogs have increased nutritional demands. Food intended only for adult maintenance may not be suitable.

How to Evaluate the Ingredient List

Ingredients are generally listed in descending order by weight before processing.

The ingredient list can help identify:

• Protein sources
• Potential allergens
• Carbohydrate sources
• Added fats
• Supplements
• Artificial colors or flavors

However, the ingredient list alone cannot show:

• Digestibility
• Overall nutrient balance
• Ingredient quality control
• Manufacturing consistency
• Bioavailability of nutrients

Does Meat Need to Be the First Ingredient?

A named animal protein near the beginning of the ingredient list may be useful information, but the first ingredient does not determine the overall quality of the food.

Fresh meat contains substantial water before processing, so its position may change when moisture is removed. Several carbohydrate ingredients may also be listed separately even when they collectively make up a significant portion of the formula.

Are Meat By-Products Bad?

By-products are not automatically low quality. Properly processed organ tissues can provide protein, vitamins, and minerals.

The nutritional value and safety of the finished formula are more important than avoiding every ingredient described as a by-product.

Are Corn, Wheat, or Soy Fillers?

Corn, wheat, and soy are not automatically useless fillers. They can provide energy, protein, fatty acids, fiber, vitamins, or minerals when properly processed and included in a balanced formula.

They may be inappropriate for an individual dog with a confirmed intolerance or allergy, but they do not need to be avoided by every dog.

Is Grain-Free Dog Food Better?

Grain-free food is not automatically healthier. Many grain-free diets replace grains with peas, lentils, potatoes, or other carbohydrate sources.

Choose grain-free food only when it is appropriate for the dog, not because grains are assumed to be harmful.

How to Read the Guaranteed Analysis

The guaranteed analysis commonly lists:

• Minimum crude protein
• Minimum crude fat
• Maximum crude fiber
• Maximum moisture

Additional nutrients may also be listed.

Comparing Wet and Dry Food

Wet and dry foods cannot be compared accurately using only the percentages printed on the package because they contain different moisture levels.

A dry-matter comparison removes water from the calculation and allows a more meaningful comparison of protein, fat, and other nutrients.

Limitations of the Guaranteed Analysis

The guaranteed analysis usually provides minimums or maximums rather than exact typical nutrient values. Contact the manufacturer if you need a detailed nutrient profile.

Calories and Portion Control

Calorie content may be listed per cup, can, tray, kilogram, or serving.

Two foods with similar-looking feeding amounts can contain very different calorie levels.

Feeding charts are starting points. Adjust the amount based on:

• Body condition
• Current weight
• Activity
• Age
• Neuter status
• Treat intake
• Medical needs

For practical portion guidance, read our article on how much food to feed a dog.

Do Not Forget Treats

Treats, toppers, chews, table scraps, and supplements with calories all contribute to daily intake.

As a general guideline, treats should remain a small percentage of total daily calories unless a veterinary professional has created a specific plan.

Are Carbohydrates Important for Dogs?

Dogs do not have a defined dietary requirement for carbohydrates in the same way they require certain amino acids and fatty acids. However, dogs can digest properly cooked carbohydrate sources, and carbohydrates can serve useful roles in dog food.

What Do Carbohydrates Do?

• Provide energy
• Supply dietary fiber
• Support stool quality
• Help create the structure of kibble
• Provide vitamins, minerals, and plant compounds
• Allow dietary protein to be used for other body functions

Dogs can also produce glucose from protein and fat. This means carbohydrates are useful but should not be described as universally essential in a specific percentage for every healthy dog.

Common Carbohydrate Sources

• Rice
• Oats
• Barley
• Corn
• Wheat
• Sweet potatoes
• Potatoes
• Peas
• Lentils

The suitability of a carbohydrate source depends on the individual dog and the complete formulation.

The Role of Fiber

Different types of fiber may support:

• Regular bowel movements
• Stool consistency
• Satiety
• Healthy gut bacteria
• Selected weight-management plans

Too much or too little fiber may cause digestive problems, so balance matters.

How Much Carbohydrate Should Dogs Eat?

There is no universal carbohydrate percentage that is ideal for every dog. Appropriate levels depend on the total diet, calorie needs, activity, health, and other nutrients.

Dogs with diabetes, obesity, gastrointestinal disease, or other medical conditions may require individualized dietary planning.

Special Dietary Needs

Food Allergies

Dogs with suspected food allergies should be evaluated by a veterinarian. Randomly switching among “limited ingredient” or grain-free foods may not identify the trigger.

A properly controlled elimination diet is more reliable.

Sensitive Digestion

Dogs with vomiting, gas, diarrhea, or inconsistent stool may benefit from changes in digestibility, fat level, fiber type, protein source, or feeding pattern.

For related guidance, read what food is good for dog digestion.

Weight Management

Weight-loss diets should provide appropriate nutrient density while reducing calories. Simply feeding much less of a standard food can also reduce essential nutrient intake.

Pancreatitis

Dogs with pancreatitis or a history of pancreatitis often need carefully controlled fat intake and veterinary guidance.

Kidney, Heart, or Liver Disease

These conditions may require adjustments to phosphorus, sodium, protein, calories, or other nutrients. Do not select a diet based only on the ingredient list.

Large-Breed Puppies

Large-breed puppies need controlled calorie and mineral intake to support steady skeletal development.

How to Evaluate the Manufacturer

Consider asking the company:

• Who formulates the food?
• What qualifications do the nutrition professionals hold?
• Where is the food manufactured?
• Does the company own the manufacturing facility?
• How are ingredients and finished products tested?
• Does the company conduct feeding studies or digestibility testing?
• Can it provide a typical nutrient analysis?
• How does it handle quality complaints and recalls?
• Is customer support easy to contact?

Manufacturer expertise and quality-control systems may provide more useful information than front-label marketing.

How to Switch Dog Food Safely

Unless a veterinarian advises otherwise, transition gradually over approximately seven days.

Dogs with sensitive digestion may need a slower transition.

During the transition, watch for:

• Vomiting
• Diarrhea
• Gas
• Loss of appetite
• Itching
• Ear irritation
• Facial swelling
• Behavioral changes

Signs a Dog Food Is Working

A suitable diet should support:

• A stable, healthy body weight
• Appropriate muscle condition
• Consistent energy
• Normal appetite
• Well-formed stools
• Healthy skin and coat
• Minimal vomiting or gas
• Normal growth in puppies

Do not judge a food only by whether the dog enjoys eating it. Highly palatable food may still be too calorie-dense or nutritionally inappropriate.

Monitor Body Condition

Your dog should generally have:

• Ribs that can be felt without excessive fat covering
• A visible waist when viewed from above
• An abdominal tuck when viewed from the side

Ask your veterinarian to assess body and muscle condition during routine appointments.

When to Consult a Veterinarian

Seek veterinary nutritional guidance if your dog:

• Is a growing puppy
• Is pregnant or nursing
• Is underweight or overweight
• Has persistent vomiting or diarrhea
• Has food allergies or chronic itching
• Has kidney, liver, heart, pancreatic, or gastrointestinal disease
• Needs a therapeutic diet
• Is losing weight or muscle unexpectedly
• Has a major appetite change
• Is being fed a homemade or raw diet

A board-certified veterinary nutritionist can help formulate or evaluate complex diets.

Frequently Asked Questions

What is the best type of dog food?

There is no single best format for every dog. The best choice is complete and balanced for the correct life stage, supports healthy weight and digestion, suits any medical needs, and can be fed consistently.

Is kibble good for dogs?

Complete and balanced kibble can be a suitable diet for many dogs. Quality, calorie density, manufacturer practices, and the dog’s response matter more than the dry format alone.

Is wet food better than dry food?

Wet food provides more moisture and may be more palatable, while dry food is usually more convenient and economical. Neither is automatically better for every dog.

Can I mix wet and dry dog food?

Yes, provided both foods are appropriate and the combined calories are controlled. Mixing foods can improve palatability but may lead to overfeeding if portions are not adjusted.

Is homemade dog food healthier?

Not automatically. Homemade food can be appropriate when professionally formulated, but unbalanced recipes can cause serious deficiencies or excesses.

Is commercial dog food bad for dogs?

No. Properly formulated commercial food can provide safe, consistent, complete nutrition. Quality varies, so evaluate the label, manufacturer, and suitability for the individual dog.

Does AAFCO approve dog food?

No. AAFCO develops nutrient profiles, model regulations, and feeding protocols but does not approve or certify individual products.

What does “complete and balanced” mean?

It means the food is intended to provide all essential nutrients in appropriate proportions for the life stage stated on the package when fed as directed.

Where is the AAFCO statement?

The nutritional adequacy statement is usually printed in small text on the back or side of the package near the ingredient list, guaranteed analysis, calorie statement, or feeding directions.

Is food tested through feeding trials better than formulated food?

Not necessarily. Feeding tests and formulation are different ways of supporting a nutritional adequacy claim. Overall quality also depends on expertise, manufacturing, testing, digestibility, and individual suitability.

Is dog food better when meat is the first ingredient?

Not necessarily. Ingredient order is based on weight before processing and does not show the quality or balance of the complete formula.

Are meat by-products bad for dogs?

No. Properly processed animal by-products can provide valuable protein, vitamins, and minerals. The finished diet’s safety and nutritional balance are more important.

Are grains bad for dogs?

Most dogs can digest properly processed grains. Grain-free diets are not necessary unless there is a specific medical reason to avoid grains.

Do dogs need carbohydrates?

Dogs do not have a defined dietary carbohydrate requirement, but they can digest cooked carbohydrates, which can provide energy, fiber, and useful nutrients.

How much carbohydrate should dog food contain?

There is no universal ideal percentage. The appropriate level depends on the complete formulation, calorie needs, activity, health, and individual tolerance.

How much food should I give my dog?

Use the package feeding guide as a starting point, then adjust for body condition, treats, activity, age, and veterinary advice.

How often should dogs eat?

Many healthy adult dogs are fed twice daily. Puppies and dogs with certain medical needs may require more frequent meals.

How should I switch dog food?

Transition gradually over approximately seven days unless your veterinarian gives different instructions. Dogs with sensitive digestion may need a slower change.

How can I tell if a food is not working for my dog?

Persistent vomiting, diarrhea, gas, itching, ear problems, poor appetite, abnormal weight change, low energy, or poor stool quality may indicate that the diet requires reassessment.

Are dog-food toppers complete and balanced?

Many are not. Products labeled as treats, toppers, mixers, or for supplemental feeding should not replace a complete primary diet.

Is expensive dog food always better?

No. Price may reflect ingredients, marketing, manufacturing, packaging, or distribution. Evaluate nutritional adequacy, quality control, calorie content, and your dog’s health response.

Final Thoughts

Choosing dog food requires more than selecting between kibble, wet food, raw food, or homemade meals. Each format can be suitable or unsuitable depending on how it is formulated, manufactured, stored, and matched to the individual dog.

Start by finding the nutritional adequacy statement and confirming that the food is complete and balanced for the correct life stage. Then review calories, feeding directions, ingredients, guaranteed analysis, manufacturer expertise, and quality-control practices.

Carbohydrates, grains, meat meals, and by-products should not be judged by marketing assumptions alone. Their role depends on the quality and balance of the finished diet.

Homemade and raw diets require particular care because nutritional imbalances and food-safety risks are easy to underestimate. Work with a veterinary professional before using these diets as a dog’s main source of nutrition.

The right food is the one that safely supports your dog’s body condition, digestion, energy, skin, coat, growth, and long-term health.
