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
Cost Analysis: Monthly & Annual Expenses
One of the most significant factors in the
kibble vs raw debate is cost. Here’s a detailed
breakdown for a 30-pound adult dog:
Premium Kibble
Monthly: $50-$100
Annual: $600-$1,200
Per meal: $0.55-$1.10
Extras: Minimal (bowl, storage container)
Commercial Raw (Frozen)

The ecological footprint of pet food is
increasingly important. 2026 research shows:
| Environmental Factor | Kibble | Raw | Analysis |
|---|---|---|---|
| Carbon Footprint | Higher (processing, transportation) | Lower (less processing) | Raw wins if locally sourced |
| Water Usage | Moderate | Higher (meat production water intensive) | Kibble often better (uses by-products) |
| Packaging Waste | Plastic bags (recyclable in some areas) | Plastic trays, foam containers | Kibble slightly better (less packaging per calorie) |
| Energy Consumption | High (extrusion, drying) | Low (freezing only) | Raw wins on processing energy |
| Food Waste Utilization | Excellent (uses by-products humans won’t eat) | Poor (uses human-grade cuts) | Kibble much better for sustainability |
Eco-Friendly
Choices for Both Diets
- Kibble: Choose brands using renewable
energy, recycled packaging - Raw: Source from regenerative farms, use
less popular protein sources (rabbit, goat) - Both: Calculate your dog’s exact calorie
needs to avoid overfeeding waste - Packaging: Look for compostable or
recyclable packaging options
Which Dog Is Each Diet Best For?
Kibble Is Best For:
- First-time dog owners
- Budget-conscious households
- Multi-dog households
- Traveling frequently
- Immunocompromised family members
- Senior dogs with dental issues
- Busy professionals
Raw Is Best For:
- Dogs with severe food allergies
- Working/performance dogs
- Dogs with chronic skin conditions
- Owners wanting maximum control
- Dogs with excellent dental health
- Households committed to food safety
- Dogs needing weight management
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.
