As you stand before the dazzling shelves of a pet food store, or scroll through various pet forums late at night, a massive question almost inevitably assaults your understanding: "What on earth should I be feeding my pet?"
On one side, you have the advocates of raw feeding (BARF), who champion a "return to nature, natural health" philosophy, showcasing their pets' glossy coats and sparkling white teeth. On the other side, you have veterinarians and nutritionists who stand by kibble, emphasizing its scientific formulation, nutritional balance, and safety. And in between these two, freeze-dried food is rising as a new, high-end option, highly sought after for offering "the nutrition of raw with the convenience of dry."
This "war of feeding methods" has plunged countless pet owners into deep anxiety. Every choice seems to have its supporters and valid reasons, yet each is also accompanied by some unsettling warnings. The purpose of this article is not to join any faction's argument. Instead, we will act as calm "scientific analysts" to provide you with an objective, in-depth breakdown of the scientifically-verified advantages (Pros) and risks (Cons) behind these three mainstream feeding methods.

The Foundation of Judgment: Understanding AAFCO and the "Complete and Balanced" Gold Standard
Before comparing any food, we must establish a benchmark that all scientific discussions cannot bypass—the AAFCO standards.
-
What is AAFCO? It stands for the "Association of American Feed Control Officials." It is not a regulatory body but a scientific organization composed of feed control officials that sets standards and regulations for the production, labeling, and sale of animal feeds and pet foods.
-
"Complete and Balanced": When a pet food package is labeled "formulated to meet the nutritional levels established by the AAFCO," it means the product has been scientifically verified to provide all the necessary nutrients in the proper proportions for a pet at a specific life stage (e.g., puppy/kitten, adult, gestation). No additional supplements are needed.
-
This is our "bottom line": Regardless of which feeding method you choose, ensuring it ultimately meets the "complete and balanced" nutritional standard is the absolute bottom line for safeguarding your pet's long-term health and avoiding nutrition-related diseases.
An In-Depth Analysis of the Three "Contenders"
Contender #1: Kibble - The Industrialized Crystallization of Convenience and Science
-
Pros:
-
Nutritionally Balanced and Stable: Kibble from reputable brands with veterinary nutritionists on staff is formulated through rigorous scientific calculations and long-term feeding trials, providing the most stable and convenient way to deliver "complete and balanced" nutrition according to AAFCO standards.
-
Safe and Hygienic: The high-heat extrusion process effectively kills most bacteria and parasites, offering a long shelf life and ease of storage.
-
Economical and Convenient: It is relatively affordable and simple to feed, making it the most practical choice for the vast majority of families.
-
Beneficial for Dental Health: The hard pellets create friction against the tooth surface during chewing, which can help reduce the formation of plaque.
-
-
Cons:
-
Highly Processed with Nutrient Loss: The high-temperature extrusion process can destroy some heat-sensitive vitamins and nutrients (reputable brands will spray these back on after processing).
-
Relatively High in Carbohydrates: The extrusion process requires a certain amount of starch, from sources like grains or legumes, for the kibble to form properly.
-
Low Moisture Content: Pets on a kibble-only diet, especially cats, require extra attention to their water intake to prevent urinary system issues from dehydration.
-
Variable Ingredient Quality: The market is flooded with brands, and some low-end products may use poor-quality ingredients or artificial attractants.
-
Contender #2: Raw Food (BARF) - The "Return to Nature" Philosophy and Its Real-World Risks
-
Pros:
-
High Digestibility and Low Stool Volume: Unprocessed animal proteins generally have high bioavailability, which can result in significantly smaller stool volume.
-
Excellent Palatability: For many picky eaters, the appeal of raw meat is unparalleled.
-
Potential Benefits: Proponents widely report that their pets have shinier coats, more energy, and cleaner teeth (from chewing on raw bones) after switching to a raw diet.
-
-
Cons:
-
The Massive Risk of Microbial Contamination: This is the number one concern of all mainstream veterinary and public health organizations.
-
Scientific Source: The U.S. Food & Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and the American Veterinary Medical Association (AVMA).
-
Core Argument: All three of these authoritative bodies have issued official statements or research reports warning of the prevalence of pathogenic bacteria like Salmonella, E. coli, and Listeria in raw meat. These bacteria can not only cause severe gastroenteritis in pets (especially the young, old, or immunocompromised) but can also be transmitted directly to humans through the pet's feces, saliva, and contaminated food bowls and kitchen surfaces, posing a serious zoonotic disease risk.
-
-
Risk of Nutritional Imbalance: For homemade raw diets, it is extremely difficult for an owner lacking professional nutritional knowledge to achieve a "complete and balanced" meal. Long-term imbalances in the calcium-to-phosphorus ratio or deficiencies in vitamins or trace minerals can lead to serious skeletal and metabolic diseases.
-
Risk of Physical Injury: Raw bones pose a risk of tooth fractures, esophageal or intestinal perforation, or obstruction in dogs.
-
Contender #3: Freeze-Dried Food - The "Middle Path" of Modern Technology
-
Pros:
-
Maximum Nutrient Retention: The lyophilization (freeze-drying) process removes moisture at low temperatures under a vacuum, which preserves the heat-sensitive vitamins, enzymes, and other nutrients in raw meat to the greatest extent.
-
The Palatability of "Raw": It retains the original flavor and aroma of the meat, making it highly appealing to picky pets.
-
The Convenience of "Dry": It is lightweight, has a long shelf life, and is easy to store and transport.
-
-
Cons:
-
Extremely Expensive: This is its biggest drawback. The cost per unit is far higher than kibble and even commercial raw food.
-
Microbial Risk Still Exists: If the raw material is raw meat, the freeze-drying process does not kill all bacteria (like Salmonella). Therefore, feeding a freeze-dried raw food still carries a certain level of microbial safety risk.
-
Must Be Rehydrated: Freeze-dried food must be fully rehydrated with warm water or broth before feeding to replenish moisture; otherwise, it can put a strain on the pet's kidneys.

Real-World Choices and Consequences: The Stories of Three Families
Case Study #1: The Champion Dog Thriving on High-Quality Kibble
-
Case Source: An interview with a professional Border Collie breeder and owner of a competitive kennel.
-
Background & Choice: This breeder owns multiple Border Collies who have won agility championships. Her choice of food is a high-end kibble from a brand that meets WSAVA (World Small Animal Veterinary Association) guidelines and has a full team of veterinary nutritionists.
-
Reason & Result: She explained, "My dogs require extremely high energy and precise nutritional ratios to support their athletic performance and joint health. For me, the most important things are stability, reliability, and scientific validation. This kibble provides all of that. My dogs are healthy, strong, have magnificent coats, and have never had a health issue related to their diet." This case proves that high-quality kibble is a scientific choice that can fully support a pet to reach its peak health.
Case Study #2: The "Family Crisis" Triggered by a DIY Raw Diet
-
Case Source: A clinical case report published in The Canadian Veterinary Journal.
-
Time & People: 2024, a family and their 1-year-old German Shepherd.
-
Problem Progression: The family, keen on "natural remedies," started preparing a homemade raw chicken diet for their dog. A few weeks later, their 5-year-old child developed severe vomiting, diarrhea, and a high fever, and was diagnosed with Salmonella enteritis. At almost the same time, their German Shepherd developed similar gastrointestinal symptoms.
-
Veterinary Intervention & Outcome: The public health department investigated and isolated the same serotype of Salmonella from the raw chicken in the family's freezer and the dog's feces, confirming it was a classic case of zoonotic disease transmission caused by raw feeding. After this traumatic physical and financial ordeal, the family ultimately abandoned raw feeding.
Case Study #3: Solving the "Picky Princess" Problem with Freeze-Dried Food
-
Case Source: A sharing post by a Bichon Frise owner on a large pet forum.
-
Time & People: 2025, an owner and her extremely picky 2-year-old Bichon, "Lola."
-
Problem Progression: Lola turned her nose up at all brands of kibble, preferring to starve rather than eat, which caused her to become underweight. The owner wanted to try raw food but was very worried about the bacterial risks.
-
Solution & Outcome: After doing extensive research, she chose a nutritionally complete and balanced freeze-dried food made with cooked meat as the primary ingredient. After rehydrating the food with warm goat's milk, Lola showed unprecedented enthusiasm for its texture and taste. The owner wrote in her post: "Freeze-dried food saved me and my dog. It satisfies Lola's craving for 'real meat' while giving me complete peace of mind about safety because the ingredients are cooked. It's expensive, but seeing her finally eat with gusto makes it all worth it."
Conclusion: There Is No "Best," Only "Most Suitable"
Raw food, kibble, freeze-dried—there is no absolute champion, only relative advantages and disadvantages. The best diet is the one that is most suitable for your pet. When making your choice, set aside the extreme, emotional rhetoric you see on social media and rationally ask yourself a few questions:
-
Is my scientific knowledge base sufficient? (If choosing to make a homemade raw diet)
-
What is my risk tolerance? (Can I accept the risk of microbial contamination?)
-
What is my budget for time and money?
-
Does my pet have any special health needs?
-
What is the recommendation of my trusted veterinarian?
Working in partnership with your veterinarian or a board-certified veterinary nutritionist to make an informed, rational, and responsible choice based on your and your pet's actual situation—that is the true core of scientific feeding.
