As a pup parent, you want to make sure your dog gets the best possible nutrition so they can live their best possible life. When choosing what to feed your dog, understanding what makes an option healthy can transform your dog’s health, energy, and longevity.

The Foundation: Essential Nutrients Your Dog Needs

Your dog depends on six fundamental compounds to maintain optimal health:

Water (dogs are nearly 80% water, just like humans)
Proteins and amino acids for strong muscles and healthy tissue
Healthy fats, especially omega-3 fatty acids for nutrient absorption and shiny coats
Carbohydrates for sustained energy
Essential minerals supporting blood and organ function
Vitamins including B vitamins, vitamin C, E, and A for immune support and healing

These nutritional building blocks work the same way in dogs as they do in humans. Dogs have evolved as facultative carnivores—meaning they thrive on both meat and plant matter, giving you flexibility in creating a balanced diet.

The Association of American Feed Control Officials (AAFCO) establishes nutritional adequacy standards that must be met or exceeded for pet food to be marketed as “complete and balanced” for specific life stages [1]. While this regulatory oversight provides baseline standards, veterinarians consistently recommend choosing the highest quality food within your budget to support your dog’s immune system, dental health, and overall wellbeing.

Why the Best Fresh Dog Food Makes All the Difference

Human Grade Dog Food: More Than Marketing

Under AAFCO’s 2023 guidelines, manufacturers must document the origins of every ingredient throughout the supply chain to make human grade claims. Human grade refers to the entire product and every ingredient in it, and all facilities must be registered as both FDA food and feed facilities [2].

The distinction between “human-grade” and “feed-grade” ingredients is critical for your dog’s health. Human-grade ingredients meet the same rigorous safety and quality standards set by the USDA for human foods, meaning you’re feeding your dog food made with the same level of care and quality you’d expect for yourself .

This isn’t just about premium pricing—it’s about fundamental safety and nutrition standards that can impact your dog’s health for years to come.

The Science Behind Fresh Dog Food Benefits

The research on fresh diets is compelling and continues to grow:

Extended Lifespan: Studies have shown that dogs fed fresh diets can live up to 2.5 years longer than those on commercial diets [3]. That’s potentially years more of morning walks, belly rubs, and cherished memories with your furry family member.

Superior Nutrition Absorption: Dogs absorb nutrients better from fresh food than kibble diets, showing higher digestibility rates for dry matter, organic matter, energy, and fats, leading to lower daily food intake because dogs absorb nutrients more efficiently [3]. This means your dog gets more nutrition from every bite.

Better Health Markers: Dogs eating fresh food have lower pro-inflammatory markers and better digestion with firmer stools, less waste, and reduced liver strain shown by lower alkaline phosphatase levels [3]. You’ll likely notice the difference in your dog’s energy levels and bathroom habits within weeks.

Cancer Prevention: Dogs need just 20% fresh food in their diet to see a 70-90% reduction in cancer cell growth [3]. Even incorporating some fresh food into your dog’s diet can provide significant protective benefits.

Fresh dog food tends to be more digestible than dry or canned dog food and may offer long-term health benefits. While more research is needed in pets, some experts believe less-processed diets may also support better long-term health in dogs [4].

Healthy Dog Food Alternatives That Actually Work

Moving Beyond Processed Kibble

While convenience and cost make dry kibble appealing to busy pet parents, your dog’s body craves moisture and whole ingredients. Fresh food, free from cheap fillers and starches, helps keep your dog at a healthy weight. Many pet foods contain inexpensive fillers (e.g., corn, wheat, rice, potatoes) so manufacturers can make more money, and starch-heavy diets lead to weight gain [5].

Think of it this way: Many commercial dog foods are comparable to fast food—loaded with unhealthy ingredients. If you eat fast food every day, your health will suffer. The same applies to dogs on a commercial diet [5].

Fresh Food: The Goldilocks Solution

Fresh, gently cooked food offers the perfect middle ground—safer than raw diets while providing superior nutrition compared to heavily processed kibble. You get the benefits of whole ingredients without the bacterial contamination risks associated with raw feeding.

Companies like Ollie solve the complexity challenge by using human-grade ingredients in recipes formulated with veterinary nutritionists, and delivering perfectly portioned meals to your door.

Best Natural Puppy Food: Special Considerations for Growing Dogs

Puppies face unique nutritional challenges during their rapid growth phases. Their developing bodies need precise nutrition ratios to build strong bones, healthy organs, and robust immune systems.

A newer guideline for puppy foods includes statements about large dogs (those over 70 pounds). Large-breed puppies grow faster than small dog breeds, and this rapid growth can lead to serious developmental orthopedic diseases (DOD). Feeding a puppy food for large breeds can lower their risk of DOD [1].

What Makes Puppy Nutrition Different

Growing puppies need:

Higher protein levels for muscle and tissue development
Controlled calcium and phosphorus ratios to prevent skeletal problems in large breeds
DHA fatty acids for brain and eye development
Smaller, more frequent meals to match their faster metabolism

The best natural puppy food combines these precise nutritional requirements with whole, recognizable ingredients. Fresh food options formulated with veterinary nutritionists—like Ollie’s recipes—meet AAFCO standards for all life stages, including the specific needs of large breed puppies.

Avoid puppy foods with excessive fillers, artificial preservatives, or generic “meat meals” that don’t specify the protein source. Your puppy’s foundation nutrition sets the stage for their entire life.

Get your puppy started right with personalized nutrition.

Dangerous Foods: What Never Belongs in Your Dog’s Bowl

Certain foods pose serious, sometimes fatal risks to dogs. As a responsible pet parent, you need to know these danger zones:

Immediately Toxic Foods

Chocolate and caffeine (methylxanthines) – cause seizures and organ failure
Xylitol (artificial sweeteners in gum, candy, some peanut butters) – causes dangerous blood sugar crashes
Grapes and raisins – kidney failure, even from small amounts
Onions, garlic, chives (alliums) – destroy red blood cells
Alcohol – never give dogs any amount
Macadamia nuts – cause weakness, vomiting, and hyperthermia

Physical Hazards

Cooked bones – splinter and cause internal injuries
Large raw bones – choking hazards that can break teeth
Fruit pits and cores – choking and cyanide risks

Keep emergency vet contact information handy and never hesitate to call if your dog ingests something questionable.

Smart Supplementation vs. Complete Nutrition

Many pet parents wonder about adding supplements to their dog’s diet. Here’s what you need to know:

University of California, Davis researchers found that 95% of homemade dog diets fail to meet canine nutritional needs [5]. This is why DIY approaches, while well-intentioned, often create more problems than they solve.

However, professionally formulated fresh foods eliminate this guesswork. The best fresh dog food comes from reputable companies who staff board-certified veterinary nutritionists and adhere to AAFCO nutrition guidelines [4].

Instead of playing supplement roulette, focus on providing complete, balanced nutrition through high-quality whole foods. When your dog’s diet is properly formulated, additional supplements are rarely necessary—and may even be harmful if they create nutrient imbalances.

Getting Professional Guidance

It is essential to work with your veterinarian or veterinary specialist to help ensure your pet is on a diet that is safe and effective.
