What Is Kibble? The Modern Manufacturing Process
Kibble (dry dog food) is created through a process called extrusion. High-quality ingredients are mixed, cooked under pressure, and forced through a die to create the familiar bite-sized pieces. This process was developed in the 1950s and has evolved significantly with 2026 nutritional science.
Kibble Manufacturing Steps:
- Ingredient Selection: Proteins, grains, vitamins, and minerals are measured
- Mixing: Dry and wet ingredients are blended into a dough
- Extrusion: Dough is cooked at 120-150°C under pressure
- Drying: Kibble pieces are dried to reduce moisture to 6-10%
- Coating: Fats, oils, and flavor enhancers are applied
- Packaging: Sealed in airtight bags with oxygen absorbers
Modern premium kibble undergoes AAFCO feeding trials to ensure nutritional adequacy. The extrusion process destroys harmful bacteria while preserving essential nutrients through careful temperature control and post-extrusion nutrient spraying.
What Is Raw Dog Food? BARF vs Prey Model
Raw dog food aims to mimic what dogs would eat in the wild. There are two main approaches:
BARF Diet
Biologically Appropriate Raw Food (70% muscle meat, 10% bone, 5% liver, 5% other organs, 10% vegetables/fruits). Developed by Dr. Ian Billinghurst in the 1990s, this model includes plant matter.
Prey Model Diet
Whole prey approximation (80% meat, 10% bone, 5% liver, 5% other organs). This model excludes vegetables and fruits, based on the argument that wild canids consume plant matter from prey stomachs.
Commercial Raw
Pre-made raw options include frozen, freeze-dried, or dehydrated formulas. These offer convenience while maintaining raw benefits. Brands like Stella & Chewy's and Primal lead this category with HACCP-certified facilities.
Homemade Raw
Owner-prepared meals offer complete control but require significant nutritional knowledge. Must be properly balanced to avoid deficiencies. Requires careful handling and food safety practices.
Top Freeze-Dried Raw Option
Best Raw Convenience
Stella & Chewy's Freeze-Dried Raw
Grain-free, protein-rich patties with 95% meat, organs, and bone. Includes organic fruits/vegetables and probiotics. Freeze-dried to lock in nutrients while eliminating pathogens. Rehydrates in minutes.

Safety Concerns: Bacterial Risks & Dental Health
Bacterial Contamination Risks
The FDA and CDC continue to warn about bacterial risks in raw diets. A 2025 study in the Journal of the American Veterinary Medical Association found:
2025 Bacterial Contamination Study Findings
- 7-25% of commercial raw diets tested positive for Salmonella
- 15-30% tested positive for Listeria monocytogenes
- 50-60% of dogs fed raw diets shed Salmonella in their feces (often asymptomatic)
- Human infection risk increases significantly in households with immunocompromised individuals
- High-pressure processing (HPP) reduces but doesn't eliminate all pathogens
Dental Health: Myth vs Reality
Proponents claim raw diets clean teeth through chewing bones. Research shows:
- Raw meaty bones do provide mechanical cleaning and enzymatic action
- Dental fractures can occur with weight-bearing bones (avoid large mammal bones)
- Kibble's cleaning effect is limited despite marketing claims ("dental diets" excepted)
- Best practice: Regardless of diet, regular tooth brushing is essential

Case Study: Two Dogs, Two Diets
In our household, we have two dogs with different needs:
Bailey (8-year-old Labrador): Has arthritis and takes NSAIDs. After consulting with a veterinary nutritionist, we keep her on a high-quality kibble with added joint supplements. The consistency helps with her medication schedule, and the controlled formulation supports her kidney health while on long-term medication.
Charlie (3-year-old Border Collie): An agility competitor with endless energy and sensitive skin. After trial and error, we found a commercial raw diet gives him optimal performance, reduced allergy symptoms, and perfect body condition. The higher protein and moisture content support his intense activity level.
This demonstrates there's no one-size-fits-all answer. The best diet depends on individual dog needs, owner lifestyle, and budget.
Transition Guide: Switching Between Diets Safely
25% New Diet, 75% Current Diet
Start with small amounts of the new food. For raw transitions, begin with single protein sources. Monitor stool consistency closely.
50% Each Diet
Equal mixing. This is when digestive issues most commonly appear. Have canned pumpkin or probiotics ready if needed.
75% New Diet, 25% Current Diet
Most dogs adjust by this point. Continue monitoring energy levels, coat condition, and stool quality.
100% New Diet
Complete transition. Adjust portions based on new food's calorie density. Schedule a wellness check with your vet after 4-6 weeks.
Critical Transition Notes
- Kibble to Raw: NEVER mix in the same meal (different digestion rates can cause issues)
- Raw to Kibble: Easier transition, but still go slowly
- Supplementation: May need probiotics or digestive enzymes during transition
- Medical Conditions: Consult your vet before switching dogs with health issues
- Puppies/Seniors: Require slower transitions (21-28 days)
Hybrid Approach: Best of Both Worlds
Many 2026 pet owners are choosing a hybrid approach, combining elements of both diets:
- 80% quality kibble as base
- 20% raw as meal topper
- Provides variety and some raw benefits
- More affordable than 100% raw
- Simplifies food safety concerns
- Kibble for weekday convenience
- Raw on weekends or special days
- Provides nutritional diversity
- Easier for multi-dog households
- Maintains gut flexibility
- Quality kibble as base
- Add raw bones for dental health
- Include fresh fruits/vegetables
- Add fish oil for omega-3s
- Probiotic supplementation
- Mix freeze-dried raw with kibble
- No thawing required
- Convenient for travel
- Lower bacterial risk than frozen raw
- More expensive than other hybrids
Final Recommendations
After analyzing hundreds of studies and thousands of owner experiences, our 2026 recommendations are:
- For most dogs: A high-quality, AAFCO-tested kibble provides complete nutrition safely and affordably
- For dogs with specific needs: Commercial raw (especially HPP-treated) can offer benefits worth the extra cost and handling requirements
- For budget-conscious owners wanting raw benefits: The hybrid approach (raw toppers or rotation) offers a practical middle ground
- Most importantly: Work with a veterinary nutritionist to create a plan tailored to your individual dog
The best diet is one that keeps your dog healthy, fits your lifestyle and budget, and that you can consistently provide. Whether you choose kibble, raw, or a hybrid approach, focus on quality ingredients, proper nutrition, and your dog's individual response.
2026 Kibble vs Raw FAQs
Is raw food really more "natural" for dogs?
Domestic dogs have evolved alongside humans for 15,000+ years and have developed amylase genes to digest carbohydrates. While their wild ancestors ate raw prey, modern dogs are genetically distinct. "Natural" doesn't always mean optimal after all, wild canids also have shorter lifespans and more parasites. The key is providing complete nutrition, whether through raw or kibble.
Can I mix kibble and raw in the same meal?
Most veterinary nutritionists now recommend against mixing in the same meal due to different digestion rates. Kibble digests slower than raw meat, which can lead to fermentation and digestive upset. Instead, feed them at separate meals or use the hybrid approaches mentioned above. If you do mix, monitor your dog closely for digestive issues.
How do I ensure my raw diet is nutritionally complete?
Follow the 80-10-5-5 rule for prey model or include appropriate plant matter for BARF. Use a nutritional balancing software or work with a veterinary nutritionist. Commercial raw diets that are AAFCO-complete take the guesswork out. For homemade, regularly rotate protein sources and include organ meats, bones, and necessary supplements (especially calcium, zinc, and vitamin E).
Are there dogs who should never eat raw?
Yes. Dogs with compromised immune systems, those on chemotherapy or immunosuppressants, households with pregnant women, young children, or immunocompromised individuals should avoid raw due to bacterial risks. Also, dogs with pancreatic issues may struggle with high-fat raw diets. Always consult your veterinarian.
What's the single biggest mistake raw feeders make?
Nutritional imbalance is the most common serious issue. Many homemade raw diets are deficient in calcium, zinc, vitamin E, or iodine. The second biggest mistake is poor food safety practices, leading to bacterial contamination. Using commercial complete raw diets or working with a nutritionist prevents these issues.
