Selecting the right food for a growing puppy means looking past the marketing on the front of the bag. The healthiest options prioritize high-quality animal protein as the first ingredient, include DHA for brain development, and avoid artificial preservatives, corn, wheat, and soy that can upset a developing digestive system. The wrong choice early on can lead to poor stool quality, low energy, and missing key nutrients during a critical growth window.
I’m Rikta — the founder and writer behind FitlyFast. I’ve spent years analyzing nutritional formulations and ingredient sourcing across dozens of pet food brands to separate genuine quality from clever labeling.
After examining ingredient panels, protein sources, and real owner feedback across different budgets, I’ve ranked the options to help you find the best all-natural puppy food for your specific breed and lifestyle needs.
How To Choose The Best All-Natural Puppy Food
Puppies have rapidly developing bones, brains, and immune systems that require precise nutrient density — not just calories. Selecting an all-natural formula means verifying that the protein source is named (chicken, beef, salmon) rather than vague by-products, and checking for guaranteed levels of DHA from fish oil or salmon oil rather than synthetic fortification. The texture matters too: small breed puppies need tiny kibble to prevent choking, while large breed puppies need controlled calcium and phosphorus levels to support steady bone growth without joint stress.
Protein Source and Single-Source Formulas
The first ingredient should always be a named meat or meat meal (deboned chicken, chicken meal, beef, salmon). Single-protein recipes help identify food sensitivities early — if a puppy develops loose stools or itchy skin, you can pinpoint the culprit without eliminating multiple ingredients. Multi-protein blends are fine for most puppies, but a single-source formula simplifies troubleshooting during the first months at home.
Kibble Size and Texture Adjustments
A 10-week-old Chihuahua cannot safely chew large kibble designed for a Labrador. Manufacturers list the recommended breed size on the bag — small, medium, large, or all-breed. Small breed formulas typically feature kibble under 8mm in diameter, while large breed kibble runs 12-15mm. Freeze-dried raw formats break into small pieces when crushed and rehydrate to a soft texture that works for puppies transitioning from wet food.
Digestive Health and Stool Quality
Consistent, formed stools are the single best indicator that a puppy food agrees with your dog. Formulas containing prebiotics (from chicory root or pumpkin), probiotics (enterococcus faecium or lactobacillus), and natural fiber from sweet potatoes or quinoa support healthy digestion. High-protein foods can sometimes cause loose stools in sensitive puppies, so starting with a small bag and monitoring stool consistency over 7-10 days is a smart strategy before committing to a large purchase.

In‑Depth Reviews
1. Open Farm Ancient Grains Chicken & Salmon
Open Farm blends 90% animal protein with ancient grains like oats and quinoa, creating a nutrient-dense formula that avoids the peas, potatoes, and legumes that trigger sensitivities in many puppies. The chicken and salmon provide a dual-protein source with omega-3 fatty acids for coat health and DHA for cognitive development. Each ingredient lot is traceable back to its geographic origin, which gives owners visibility into sourcing that most brands don’t offer.
This recipe is particularly effective for puppies with sensitive stomachs — the unrefined ancient grains are easier to break down than corn or soy-based fillers. The kibble size is medium, making it suitable for medium and large breed puppies, though small breeds may struggle with the larger pieces. Owners report consistently firm stools and sustained energy levels after switching from cheaper grain-heavy brands.
One trade-off is the 4 lb bag size, which goes quickly for medium and large breed puppies and may require frequent reordering. The chicken and salmon recipe also contains fish, so puppies with known seafood allergies should be tested cautiously. For owners who prioritize ingredient transparency and gentle digestion, this is the most balanced premium option available.
Why it’s great
- 90% animal protein with named meat sources
- Ancient grains support sensitive digestion
- Ingredient traceability to farm origin
- No artificial flavors, preservatives, or additives
Good to know
- Medium kibble may be too large for tiny breeds
- Contains fish allergen
- Small bag requires frequent repurchase for larger puppies
2. Instinct Puppy Freeze-Dried Raw Chicken
Instinct’s FreshDried Bites deliver 85% cage-free chicken meat and organs with 15% non-GMO fruits and vegetables, locking in raw nutrition through a freeze-drying process that preserves enzymes and natural DHA. This format eliminates the need for refrigeration while maintaining the nutrient profile of a raw diet. The small, crumbly pieces rehydrate quickly and work as a full meal or a topper for picky eaters.
Natural DHA, calcium, and phosphorus are included at levels that support brain development, strong bones, and healthy teeth during the first year. Owners of small and medium breed puppies report improved coat shine, higher energy levels, and enthusiastic mealtime responses. The 25 oz bag is compact but dense — a little goes a long way when rehydrated, making it more cost-effective than its raw format suggests.
This food is grain-free and contains no corn, wheat, soy, or legumes, making it suitable for puppies with multiple food sensitivities. Some owners note that using it as the primary food rather than a topper increases the per-serving cost significantly. The chicken protein means it’s unsuitable for puppies with known poultry allergies.
Why it’s great
- 85% meat and organs for high bioavailable protein
- Freeze-drying preserves natural DHA and enzymes
- Rehydrates quickly for easy feeding
- No artificial colors, preservatives, or grain fillers
Good to know
- Small bag size limits use as primary food for larger breeds
- Chicken allergen present
- Per-serving cost is higher than kibble-only formulas
3. Wellness Complete Health Puppy Chicken & Salmon
Wellness Complete Health delivers a grain-free formula with chicken as the primary protein and salmon oil providing guaranteed levels of DHA for brain development. The 24 lb bag offers the best per-pound cost among premium puppy foods on this list, making it practical for medium and large breed owners who go through bags quickly. The kibble is medium-sized and designed to be easily chewed without being too small to encourage gulping.
Omega-6 and omega-3 fatty acids from salmon oil support healthy skin and a shiny coat, while antioxidants from blueberries and spinach bolster the immune system during the first year. Owners consistently report firm, well-formed stools and less waste overall — the higher digestibility means the puppy absorbs more nutrients and produces fewer bowel movements compared to lower-quality brands. This is a measurable benefit for owners who want clean yard cleanup and efficient feeding.
The recipe contains no corn, wheat, soy, or poultry by-products, though it does include chicken, so puppies with poultry allergies should avoid it. A small percentage of owners note that the protein level is moderate compared to high-protein raw formulas, but this controlled protein level actually reduces gas and loose stool in puppies that don’t tolerate high-protein diets well.
Why it’s great
- Large 24 lb bag delivers strong value per pound
- Guaranteed DHA from salmon oil
- Produces firm, consistent stools
- No artificial colors, preservatives, or by-products
Good to know
- Contains chicken protein
- Moderate protein level may not suit high-energy large breeds
- Kibble is medium — not optimized for very small breeds
4. Merrick Texas Beef & Sweet Potato
Merrick’s formula uses real deboned Texas beef as the first ingredient, delivering 70% of its total protein from animal sources alongside glucosamine and chondroitin for healthy hip and joint development. The 52% combined protein and healthy fat ratio provides the caloric density needed for active, growing puppies that burn through energy quickly. The smaller kibble size is specifically designed for puppy mouths and works well across medium and large breeds.
DHA is included to support brain development, while omega-6 and omega-3 fatty acids nourish skin and coat. The sweet potato provides a natural fiber source that helps maintain firm stools without the digestive issues that can accompany high-protein foods. Owners report enthusiastic eating and steady weight gain in puppies that previously turned away from chicken-based formulas.
The grain-free recipe is gluten-free and contains no corn, wheat, or soy, though the beef protein means it’s unsuitable for puppies with red meat sensitivities. Some owners transitioning from chicken-based foods noted a temporary runny stool period of 5-7 days before the puppy adjusted. The 10 lb bag is smaller than the Wellness 24 lb offering, so the per-pound cost is higher for owners feeding large breed puppies.
Why it’s great
- Deboned beef is the first ingredient
- 70% of protein from animal sources
- Glucosamine for joint health in growing pups
- Smaller kibble size for easier chewing
Good to know
- Beef protein may not suit all puppies
- Transition period may cause temporary loose stools
- Smaller bag size increases per-pound cost for large breeds
5. Royal Canin Size Health Nutrition Small Puppy
Royal Canin targets puppies with an expected adult weight of 9 to 22 lbs, providing tiny kibble that small breed mouths can pick up and chew without risk of choking. The formula includes specialized antioxidants to support immune system development, prebiotics for gut health, and DHA from natural sources for brain development. Breeder recommendations are common for this brand because the kibble size eliminates the need for soaking or crushing for toy breeds like Chihuahuas and Bichons.
Chicken is the primary protein, and the crunchy texture helps reduce tartar buildup during the teething phase. Owners of picky small breed puppies report that the tiny pellets are accepted even when other brands are refused. The 4 lb bag is appropriately sized for toy breeds that eat small portions, though it may require frequent reordering for households with multiple small dogs.
This is not a grain-free formula and contains wheat and gluten, which may not be ideal for puppies with confirmed grain sensitivities. The ingredient list is less transparent about meat sourcing compared to Open Farm or Smallbatch, and the protein content is lower than high-protein options. It’s a targeted solution for small breed owners who prioritize correct kibble size and digestive ease over maximum protein percentages.
Why it’s great
- Kibble is perfectly sized for 2-10 lb puppy mouths
- Prebiotics and antioxidants support gut and immune health
- DHA for brain development
- Crunchy texture helps clean teeth
Good to know
- Contains wheat and gluten
- Lower protein content than grain-free options
- Less transparent ingredient sourcing than premium brands
6. Smallbatch Freeze-Dried Raw Beef
Smallbatch Pets uses 88% grass-fed beef including hearts, livers, kidneys, and bones, mixed with 10% organic produce and 2% natural supplements to create a single-protein raw diet that meets AAFCO nutrient profiles for all life stages. The freeze-dried format preserves the nutrient density of raw meat without requiring freezer space, and the sliders rehydrate in minutes when crushed and mixed with warm water. This format is especially effective for picky eaters who reject kibble textures.
The single-source beef protein makes it easy to rule out food sensitivities — if a puppy thrives on this formula, chicken or fish allergies are not a concern. Owners of senior dogs and puppies alike report improved coat shine, higher energy, and better digestion. The 14 oz bag is dense and feeds a small breed puppy for about two weeks when used as a primary food, though it works best as a topper or treat for medium to large breeds due to the cost.
Some owners find the sliders difficult to break into even pieces, particularly in colder weather when the freeze-dried blocks are harder. The beef-only formula may not provide the variety that some puppies prefer, and the per-serving cost is among the highest on this list when used as a complete meal.
Why it’s great
- 88% grass-fed beef with organs for natural nutrition
- Single-source protein simplifies allergy identification
- Organic produce and natural supplements included
- Meets AAFCO for all life stages
Good to know
- Sliders can be difficult to break into small pieces
- High per-serving cost as a primary food
- Only beef flavor available
7. Wellness CORE Large Breed Puppy Chicken & Turkey
Wellness CORE Large Breed formula is designed to meet the specific needs of puppies expected to weigh 50 lbs or more as adults, with controlled fat and calorie levels to prevent rapid growth that stresses developing joints. The 45% high-quality protein from responsibly sourced chicken and turkey supports lean muscle development, while glucosamine and chondroitin provide joint support that large breed puppies need during their skeleton-building first 18 months.
Probiotics and high fiber content promote digestive regularity — a major advantage for large breed puppies that are prone to loose stools and gas on high-protein diets. Omega fatty acids support skin and coat health, and taurine contributes to healthy heart function. Owners of German Shepherds, Labrador Retrievers, and Golden Retrievers consistently report fewer stomach issues, improved coat quality, and sustained energy without the hyperactivity spikes seen with lower-quality foods.
This formula is marketed as adult food but is commonly used for large breed puppies due to its balanced nutrient profile — the bag itself does not explicitly label it as a puppy formula, so owners should confirm it matches their vet’s growth recommendations. The 26 lb bag provides strong value for large breed households, though the chicken and turkey blend means it’s unsuitable for puppies with poultry allergies.
Why it’s great
- Formulated for large breed growth with controlled calories
- Glucosamine and probiotics for joints and digestion
- High protein from named chicken and turkey
- Excellent stool quality and reduced gas
Good to know
- Not explicitly labeled as puppy food
- Contains poultry protein
- Some Amazon delivery issues reported
