Complete vs Complementary Raw Food: What’s the Difference?

When choosing raw food for your dog, one of the most important things to understand is the difference between complete and complementary raw food.

These terms are not just marketing words — they tell you whether a product is designed to provide everything your dog needs as a daily diet, or whether it needs to be combined with other foods to create a balanced meal plan.

What Is a Complete Raw Food?

A complete pet food is formulated to provide all the essential nutrients a healthy dog requires when fed according to the manufacturer's guidelines.

A complete raw food should contain the correct balance of nutrients, including:

• Protein and essential amino acids

• Fats and essential fatty acids

• Vitamins

• Minerals

• Appropriate calcium and phosphorus levels

• Other nutrients required for health

Complete foods are designed to be fed as the main diet and are often the easiest option for owners who are new to raw feeding, as the nutritional balancing has already been done by the manufacturer.

Always check the packaging — a product intended to be complete should be clearly labelled as "Complete Pet Food".

What Is a Complementary Raw Food?

A complementary pet food is a product that is intended to be fed alongside other foods to create a balanced diet.

Examples include:

• Single-protein minces

• 80:10:10 products

• Raw meaty bones

• Organ meats

• Some treats and toppers

These foods can be a valuable part of a raw feeding plan, but they are not necessarily designed to provide every nutrient your dog needs on their own.

For example, a mince containing meat, bone and offal may provide many important nutrients, but depending on the formulation it may still need additional ingredients to achieve a complete nutritional profile.

Why Are Some Raw Foods Complementary?

Not every raw product is designed to be a complete meal.

Some owners prefer to build their dog's diet themselves using different ingredients, rotating proteins and balancing meals over time. Complementary foods provide flexibility and allow owners to create varied feeding plans.

However, creating a balanced DIY raw diet requires knowledge and careful planning, particularly for puppies, pregnant dogs, growing dogs and dogs with specific health needs.

Can I Feed Complementary Food Every Day?

This depends on the product and how it is being used.

Some complementary products can form part of a balanced diet when combined correctly with other ingredients. However, feeding a complementary food as the only diet long-term may result in nutritional gaps.

Always check the feeding instructions and product label. If you are unsure, ask the manufacturer, your retailer or a suitably qualified nutrition professional.

Can I Mix Complete and Complementary Raw Food?

Yes, many owners choose to include both.

For example, someone might feed a complete raw food as the main diet and use complementary products such as:

• Different proteins for variety

• Raw meaty bones

• Fish

• Treats

• Enrichment chews

The important thing is understanding what each product contributes to your dog's overall diet.

If adding extras, remember that treats and toppers should still be considered as part of your dog's overall intake.

How Do I Know Which One I Am Buying?

The easiest way is to read the label.

Look for:

Complete Pet Food

• Suitable as a daily diet when fed according to instructions.

• Designed to provide all required nutrients.

Complementary Pet Food

• Intended to be fed with other foods.

• May not provide all nutrients required on its own.

If you're unsure, ask before buying. A good raw food supplier should be able to explain the difference and help you choose products suitable for your dog's needs.

What About 80:10:10?

80:10:10 is a popular raw feeding ratio based around:

• 80% muscle meat

• 10% edible bone

• 10% offal (including liver)

Many owners use 80:10:10 products as part of their dog's diet, but they are commonly labelled as complementary foods because the ratio alone does not necessarily guarantee that every nutritional requirement is met.

Some dogs thrive on carefully planned DIY diets, while others benefit from the simplicity of a complete commercial raw food.

Is Complete Better Than Complementary?

Neither is automatically "better" — they serve different purposes.

A complete raw food can be an excellent choice for owners wanting convenience and reassurance that nutritional requirements have been considered.

Complementary foods can provide variety and flexibility for experienced raw feeders who understand how to create a varied diet.

The best choice depends on:

• Your knowledge and confidence

• Your dog's age and health

• Your lifestyle

• The amount of time you want to spend preparing meals

• Complementary foods need to be combined with other foods.
