Dog Nutrition in India: AAFCO & NRC Standards Every Pet Owner Should Know

Every cell, organ, and function in your dog's body depends on the nutrients they consume. Protein builds and repairs muscles and tissues. Fats provide energy and support brain and skin health. Carbohydrates supply accessible energy. Vitamins and minerals regulate everything from bone development to immune function and nerve signaling. When any of these are insufficient, in excess, or imbalanced, the consequences range from poor coat condition and low energy to organ failure and shortened lifespan. A dog can appear healthy on a poor diet for months or even years before the damage becomes visible — making evidence-based nutrition critically important rather than an afterthought.

AAFCO (Association of American Feed Control Officials) publishes nutrient profiles that define the minimum and maximum levels of key nutrients in commercial dog food. These are the most widely used standards for dog food in the world, including in India. Below are key AAFCO minimums on a Dry Matter (DM) basis:

Nutrient | Adult Minimum | Puppy/Growth Minimum

Protein | 18.0% | 22.5%

Fat | 5.5% | 8.5%

Calcium | 0.5% | 1.0%

Phosphorus | 0.4% | 0.8%

Potassium | 0.6% | 0.6%

Sodium | 0.08% | 0.3%

Linoleic Acid | 1.1% | 1.1%

Vitamin A (IU/kg) | 5000 | 5000

Vitamin D (IU/kg) | 500 | 500

Vitamin E (IU/kg) | 50 | 50

Dry Matter basis means nutrients are measured after removing all moisture from the food. When comparing wet and dry foods, always convert to DM basis. A food labeled 'complete and balanced' by AAFCO standards has been formulated to meet these minimums.

The NRC (National Research Council) publishes 'Nutrient Requirements of Dogs and Cats' — a comprehensive scientific review of individual nutrient research. NRC recommendations are based on per-kilogram-of-body-weight nutrient needs derived directly from controlled feeding studies, making them more precise but also more complex to apply in practice. AAFCO, by contrast, takes NRC science and translates it into practical food formulation standards with safety margins, making AAFCO the standard used by pet food manufacturers.

Key difference: NRC tells you exactly how much of each nutrient a specific dog needs based on their size and life stage. AAFCO tells pet food companies what minimum levels to include in food to meet the needs of most dogs. For the average pet owner, AAFCO-certified food is the practical standard to aim for. For dogs with specific medical conditions or unusual dietary needs, NRC-level precision (with veterinary guidance) becomes relevant.

In India, pet food is regulated by FSSAI (Food Safety and Standards Authority of India) under the Food Safety and Standards (Food Products Standards and Food Additives) Regulations. FSSAI-compliant pet food labels should show: the product name and species it is intended for, a guaranteed analysis listing minimum crude protein, minimum crude fat, maximum crude fiber, and maximum moisture, an ingredient list in descending order by weight, feeding guidelines, manufacturer name and address, and net weight. Look for the phrase 'complete and balanced nutrition' or a statement indicating the food meets AAFCO nutrient profiles — this tells you the food has been formulated to science-based standards. Be cautious of products that only list 'crude' nutrients without specifying whether they meet any recognized nutritional standard.

Pawsnexus vets in Bengaluru see the same nutritional mistakes repeatedly. Feeding primarily roti and rice: these are high in simple carbohydrates and low in the protein, essential fats, and micronutrients dogs need. Used as occasional treats, they are harmless — as a staple diet, they cause deficiencies. Giving cows milk: most adult dogs are lactose intolerant and milk causes digestive upset. Feeding home-cooked food without balance: home-cooked diets can be healthy but require careful formulation — without supplementation, they almost universally lack calcium, essential vitamins, and trace minerals. Over-supplementing: adding calcium or vitamin D supplements to a dog already eating a complete commercial food can cause toxicity and skeletal problems. Feeding spicy, salty, or onion-containing food: onion and garlic are toxic to dogs and common in Indian cooking. Never share table food seasoned with these ingredients.

If you are unsure whether your dog's current diet is meeting their nutritional needs, a Pawsnexus vet home visit includes nutritional assessment and personalized dietary advice. We evaluate your dog's body condition score, current diet, life stage, and health status to provide practical, evidence-based recommendations. Whether you feed commercial food, home-cooked meals, or a combination, we can help you ensure your dog's nutritional needs are fully met.
