How much raw food to feed a puppy is the question that shapes your dog’s entire first year, their bone density, joint development, immune strength, and long-term health. Yet a 2023 survey by the UK Raw Feeding Veterinary Society found that nearly 60% of owners who switched to raw underestimated how much portion requirements shift week by week during a puppy’s growth phase. That gap between intention and execution is exactly where preventable harm happens.
This guide covers everything in one place: weekly feeding calculations, age-by-age charts with real gram examples, the clinical science behind calcium and phosphorus balance, BARF and PMR ratio breakdowns, the micronutrients most raw diets miss, and the monitoring habits that keep your puppy on track. Every figure is drawn from veterinary research and clinical evidence.

Is Raw Food Good for Puppies?
Yes, when the diet is properly balanced. Done right, raw feeding gives a developing puppy the biological foundation that processed food struggles to match: better dental health from the mechanical action of chewing raw meat and bone, lean controlled growth rather than fat-padded rapid weight gain that stresses joints, dramatically smaller and firmer stools because the food is actually used rather than passed, a richer gut microbiome that builds long-term immune competence, and noticeably better coat condition within two to three weeks of switching.
“A nutritionally complete raw diet can support excellent development in puppies. The critical word is “complete”; the diet must include the right balance of bone, organ, and muscle meat, alongside key micronutrients that are easy to miss in home-prepared diets. ” [Dr. Sarah Dodd, BVSc, MSc, PhD candidate, Veterinary Nutritionist]
The caveat is real, though. A 2024 PMC-published case series documented four large-breed puppies developing nutritional secondary hyperparathyroidism with pathological fractures after being fed exclusively boneless raw meat. The science is unambiguous: a balanced raw diet is excellent; an unbalanced one causes serious, sometimes irreversible harm. Every section below is built to keep you firmly in the first category.
When Can Puppies Have Raw Food?
Earlier than most owners expect. Finely minced raw meat can be introduced as a weaning supplement from around three to four weeks alongside the mother’s milk. By seven to eight weeks, the standard age UK puppies arrive in their new homes; the vast majority are ready for a complete raw diet from day one.
For three to four weeks, use tiny amounts of fine raw mince. Between four and seven weeks, ground raw meat works well, but skip the whole bone at this stage; the jaw is not ready for it. From seven to eight weeks, soft edible bone can be introduced: chicken wing tips and small chicken necks are ideal starters because they are soft enough to be safe but firm enough to begin building jaw strength. By eight weeks onwards, the puppy is ready for the full feeding protocol described in this guide.
Meal timing matters as much as total daily quantity. Knowing puppy feeding frequency at each growth stage keeps metabolism stable as your puppy develops.
How Much Raw Food to Feed a Puppy: The Two Core Methods
There are two primary frameworks for calculating how much raw food to feed a puppy. Choose based on your puppy’s size and how hands-on you want to be.
Method A: Current Body Weight Percentage Most Accurate
Feed a percentage of your puppy’s actual current weight, recalculated every single week. This is the most responsive method because it mirrors the non-linear reality of puppy growth, with peak metabolic demand at eight weeks, progressively decreasing as the puppy approaches adult size. The weekly recalculation is non-negotiable: skipping even two or three weeks means your portion could be 20 to 30% off by the time you notice.
Puppy Raw Feeding Chart by Age
| Age | % of Current Weight Daily | Meals Per Day |
|---|---|---|
| 7 – 10 Weeks | 8% – 10% | 4 meals |
| 10 – 16 Weeks | 7% – 8.5% | 3 – 4 meals |
| 4 – 5 Months | 6.5% – 7.5% | 3 meals |
| 6 – 9 Months | 4.5% – 5.5% | 2 meals |
| 9 – 12 Months | 3% – 4% | 2 meals |
| 12+ Months (Adult) | 2% – 3% | 1 – 2 meals |
Pro Tip:
A 2.5 kg puppy at 8 weeks needs 200 to 250 g daily across 4 meals of 50 to 62 g each. By 16 weeks at 5 kg, that becomes 350 to 425 g daily. Weigh every 7 days, and recalculate each time; this single weekly habit is more important than any other in raw feeding.
Method B: Estimated Adult Weight Simpler and Consistent
Feed 2 to 2.5% of your puppy’s projected adult weight throughout the growth phase. A Labrador expected to reach 30 kg gets 750 g daily from weaning through to adulthood. Simple, consistent, no weekly recalculation. The trade-off is precision in early puppyhood, when 2 to 3% of adult weight can underestimate a very young puppy’s true caloric needs. For mixed-breed puppies, Method A is always more reliable because adult weight prediction is difficult.
Alongside portion size, getting your daily meal schedule right is just as important for a developing puppy. Even with the right portions, your puppy’s metabolism depends on a structured puppy feeding schedule by age to ensure they are digesting these grams effectively from weaning through to adulthood.
What Does That Actually Look Like in Grams?
Percentages become real when you see actual weights. At 8 weeks, a small breed puppy weighing around 1.2 kg needs roughly 96 to 120 g of raw food daily across four meals, about 24 to 30 g per meal, which sits comfortably in the palm of your hand. A medium breed at 3 kg needs 240 to 300 g daily. A large breed at 4.5 kg needs 360 to 450 g.
By 12 weeks, those numbers have already shifted considerably. Your small breed puppy is now around 2 kg and needs 140 to 170 g daily. The medium breed at 6 kg needs 420 to 510 g. The large breed at 9 kg needs 630 to 765 g. This pace of change is precisely why weekly weighing exists; a three-week gap can mean you are 25% off the right portion without realising it.
Why Breed Size Changes Everything
Not all puppies grow at the same rate, and feeding the same percentage to a Chihuahua and a Great Dane will give very different results. Here is what changes by size
Small and Toy Breeds
Small breed puppies have proportionally faster metabolisms and reach adult size by 9 to 10 months. Feed at the higher end of every age band and maintain four meals daily until at least four months. For Chihuahuas and other toy breeds, feeding small breed puppies correctly is less about total weight and more about how that amount is split across the day; skipping even one meal at this stage disrupts metabolic stability in ways that larger breeds simply do not experience.
Large and Giant Breeds
Large breed puppies are the highest-risk group in raw feeding. Their growth plates stay open until 18 to 24 months, far longer than those of small breeds. Overfeeding drives rapid growth that mechanically stresses unmineralized cartilage, directly contributing to hip dysplasia, elbow dysplasia, and osteochondrosis. Always feed at the lower end of every percentage band. A large breed puppy that looks slightly lean is far less at risk than one that looks well-filled.
In large and giant breed puppies, the most common nutrition-related orthopedic mistake I see is owners overfeeding in the belief that a bigger, heavier puppy is a healthier one. The opposite is true. Lean, slow, controlled growth is the target, not rapid size. Dr Brennen McKenzie, MA, MSc, VMD, cVMA, Veterinary Internal Medicine
For giant breeds, Great Danes, Mastiffs, and Irish Wolfhounds use the RER formula rather than simple percentages: 70 × (body weight in kg)^0.75, then multiply by 3.0 for puppies under four months and 2.0 from four to twelve months. A 10 kg puppy at three months has an RER of approximately 394 kcal, meaning a daily requirement of around 1,182 kcal.
BARF vs PMR: Which Model Is Right for Your Puppy?
Can puppies eat raw dog food following either BARF or PMR? Yes, both are valid and widely used in the UK. The choice comes down to your philosophy on plant material and how you want to structure the diet.
PMR (Prey Model Raw)
PMR is strictly animal-based muscle meat, raw bone, and organs only, with no plant material. For puppies, the adult ratios are adjusted to increase bone content during the skeletal mineralization window. Muscle meat, including heart, makes up 64 to 69% of the diet, heart being the most important natural taurine source. Raw edible bone sits at 17%, elevated above the 10% recommended for adults, directly reflecting a growing puppy’s calcium and phosphorus demands. Liver accounts for 7%, delivering vitamin A and copper. Other secreting organs, the kidney, spleen, and pancreas, make up a further 7%, providing zinc, manganese, and a broad spectrum of trace minerals. A small amount of animal fiber, fur, or feathers can be added for gut motility.
BARF (Biologically Appropriate Raw Food)
BARF, developed by Dr. Ian Billinghurst, treats the dog as a facultative carnivore adapted to digest pulverized plant material from prey gut contents. Muscle meat drops to 58%, raw edible bone remains at 17%, and the remaining proportions split across lightly blended vegetables for fiber and phytonutrients at 7%, liver at 7%, other organs at 7%, seeds and nuts for Omega-6 and Vitamin E at 3%, and a small amount of fruit for antioxidants at 1%. Both models target the same 17% bone for puppies; that figure does not change regardless of which framework you follow.
Calcium and Phosphorus: The Number One Clinical Risk
More puppies are harmed by calcium-phosphorus imbalance than by any other raw feeding error. Understanding this is not optional; it is the most important piece of knowledge in this entire guide.
The target calcium to phosphorus ratio for a growing puppy is 1:1 to 1.2:1. Phosphorus is abundant in muscle meat. Calcium comes primarily from raw edible bone. When a puppy eats only boneless raw meat with no bone component, the clinical sequence is clear: high phosphorus triggers the parathyroid gland to release PTH, which instructs osteoclasts to dissolve the puppy’s own bone tissue to restore blood calcium. This is nutritional secondary hyperparathyroidism. It progresses until bones fracture under normal body weight.
Puppies under six months have no regulatory mechanism for calcium absorption their bodies take in nearly all dietary calcium regardless of actual need. This makes them uniquely vulnerable to both deficiency and excess. The margin for error is genuinely narrow at this stage of development.
Clinical Evidence:
A 2024 case series published in PMC documented four large-breed puppies presenting with neurological deficits and generalised osteopenia bones appearing translucent on radiographs after being fed exclusively boneless raw meat. A separate case recorded an 8-month-old Shetland Sheepdog fed a mineral imbalanced raw diet presenting with neck pain, collapse, and floating dental arcades teeth losing their bony anchorage because the underlying bone had been dissolved. Skeletal deformities established during the growth phase are frequently permanent even after dietary correction.
Vitamin D is equally non-negotiable. Unlike humans, dogs cannot synthesise Vitamin D from sunlight; they depend entirely on dietary intake. Without adequate Vitamin D, calcium absorption fails even when the bone content in the diet is correct. The result is rickets or rubber jaw syndrome: the mandible and maxilla become soft and pliable from failed mineralisation. Feed fatty fish at least twice weekly or supplement with Vitamin D3.
Nutritional imbalance, including the sudden dietary shifts that raw feeding transitions can cause, sometimes triggers acute gastrointestinal symptoms including blood in a puppy’s stool particularly in the first weeks of a raw diet.
Raw Meaty Bones: Bone Content Reference
Knowing the actual bone percentage of each cut you use is a foundational skill. A chicken wing and a chicken thigh are both raw food one is nearly half bone, one is mostly meat. Feeding the wrong combination produces a diet that looks balanced but is calcium-deficient in practice.
| Raw Meaty Bone | Bone % | Meat % | Best For |
|---|---|---|---|
| Chicken wing tip | 60% | 40% | 8 weeks+ softest starter bone |
| Chicken neck | 36% | 64% | 8 weeks+ most common UK raw cut |
| Chicken wing (whole) | 46% | 54% | 8 weeks+ widely available |
| Chicken back | 44% | 56% | Pair with boneless meat to hit 17% |
| Duck neck | 50% | 50% | 12 weeks+ medium breeds |
| Turkey neck | 42–45% | 55–58% | 12 weeks+ medium and large breeds |
| Rabbit whole (no fur) | 28% | 72% | Sensitive puppies lean protein |
| Beef ribs | 52% | 48% | 16 weeks+ large breeds, supervised only |
| Lamb ribs | 27% | 73% | Lower bone is good for variety |
How to Calculate Your Bone %:
Bone calculation: 200 g of chicken wings = 200 × 0.46 = 92 g actual bone. With a 1,000 g daily intake that is only 9.2% well below the 17% puppy target. Correct by reducing boneless meat and replacing with higher-bone cuts such as chicken backs or wing tips.
Four Micronutrients Most UK Raw Diets Miss
A 2025 Texas A&M University study found that the majority of homemade dog diets, including raw, are deficient in at least one essential nutrient. For growing puppies, these gaps compound over months. These four are the most consistently absent.
-
Iodine
is essential for thyroid hormones that regulate growth and neurological development. It sits primarily in the thyroid gland, which most raw feeders cannot access. Without supplementation, virtually every home-prepared raw diet is iodine-deficient. Use kelp (Ascophyllum nodosum) with a guaranteed iodine analysis. Generic kelp powders vary wildly in iodine content; too much triggers hyperthyroidism just as too little causes deficiency.
-
Zinc
is required for over 300 metabolic enzymes. Deficiency in puppies presents as stunted growth and zinc-responsive dermatosis, a distinctive crusting around the eyes, muzzle, and paw pads, frequently misdiagnosed as allergies. Best sources are beef, lamb, pumpkin seeds, and oysters. High dietary calcium inhibits zinc absorption, which is another reason to hold bone content at exactly 17% rather than well above it.
-
DHA ( Omega- 3 )
is a structural component of the developing brain and retina. The neurological architecture built in the first twelve weeks of life is largely DHA-dependent. Dogs convert less than 5% of plant-based ALA into usable DHA, so flaxseed is not a meaningful source. Feed fresh oily fish, such as sardines, mackerel, and herring, two to three times weekly, or use a fish oil supplement providing pre-formed EPA and DHA at around 50 to 75 mg per kilogram of body weight daily.
-
Vitamin D
cannot be synthesised from sunlight by dogs; it must come from food. Deficiency causes calcium absorption failure even when bone content is correct, producing rickets or rubber jaw. Fatty fish, egg yolks, and beef liver in appropriate quantities are the best dietary sources. If oily fish is not fed at least twice weekly, supplement with a vet-recommended Vitamin D3
Can Puppies Eat Raw Dog Food Safely?
Can puppies eat raw dog food without creating risks in your home? Yes, with consistent hygiene management. A healthy puppy’s stomach pH of 1–2 neutralises most pathogens. The primary risk is not to the puppy. It is for the humans sharing the household. For the BVA’s full position on raw feeding safety, including the risks and safeguards they recommend, see BVA’s official guidance on raw meat-based diets.
A raw-fed puppy can carry Salmonella, Listeria, or E. coli without any signs of illness and then excrete those bacteria in faeces, where they survive for days. In households with young children, pregnant women, elderly individuals, or immunocompromised members, this requires active management rather than occasional awareness.
The core rules are straightforward. Never leave raw food in the bowl for more than 30 minutes. Use a dedicated, labelled chopping board and knife for raw pet food only; never cross-contaminate with human food preparation. Sanitise all bowls, surfaces, and utensils with dilute bleach or a pet-safe disinfectant after every use. Wash your hands immediately after handling raw meat or touching the puppy’s mouth. Store defrosted raw sealed at the bottom of the fridge and defrost overnight, never at room temperature. If anyone in your home is pregnant or immunocompromised, HPP (High-Pressure Processed) commercial raw significantly reduces pathogen risk without compromising nutritional integrity. These rules align with the UK Food Standards Agency’s raw pet food safety protocols, which set the official standard for raw pet food handling in UK households.
“The microbiological risk of raw pet food is manageable with strict kitchen hygiene, but it is real. Owners should treat raw pet food preparation with the same care they apply to raw chicken for human consumption because the pathogens involved are largely the same.” [Dr Ian Battersby, BVSc DSAM DipECVIM-CA MRCVS, RCVS Specialist in Small Animal Internal Medicine]
Is Your Portion Right? Five Things to Check Weekly
Charts tell you where to start. Your puppy’s body tells you whether it is working. This five-minute weekly assessment keeps you accurate throughout the growth phase — and it is more reliable than any calculation.
Signs of Underfeeding
-
Ribs visible without touching:
You should never see the outline of a raw-fed puppy’s ribs. If you can, increase the daily portion by 10% and reassess after one week.
-
Frantic, persistent hunger:
Some food enthusiasm is normal in puppies. Genuinely frantic behaviour at mealtimes, or attempts to eat inedible objects, suggests caloric intake is insufficient.
-
Low energy after 8 weeks:
A well-nourished puppy is energetic during waking periods. Persistent lethargy beyond the neonatal stage suggests the diet is not meeting energy needs.
Signs of Overfeeding
-
Ribs not palpable with light pressure:
Press two fingers lightly on the ribcage. Ribs should be felt easily, like pressing the back of your hand. If you need force, reduce by 10%.
-
Round pot belly:
From above, a visible waist should be present. From the side, an abdominal tuck. A rounded belly is not healthy puppy chubbiness in large breeds it directly loads developing growth plates.
-
Stool tells you the truth:
Soft or loose stools suggest excess fat or overfeeding. White chalky stools mean too much bone; reduce bone-heavy cuts immediately. Small, firm, dark, low-odour stools mean the balance is correct.
Treats and Chews: The Hidden Portion Most Owners Ignore
Every treat, training reward, and recreational chew counts toward your puppy’s daily total. Ignore them, and your calculated portion becomes inaccurate before the day is halfway done.
The rule is simple: treats are deducted from the daily portion, not added on top. A puppy receiving 400 g daily who also receives 60 g of liver treats through training sessions is effectively eating 460 g, an extra 420 g across the week, without anyone intending it.
For practical adjustment: small training treats of five to ten pieces add roughly 20 to 40 kcal, so reduce the main meal by 15 to 20 g. A chicken neck used as a recreational chew adds 60 to 80 kcal reduce the main meal by 50 to 65 g. A duck neck adds 100 to 130 kcal reduce by 80 to 105 g.
Important: Liver as a training treat needs specific management. It is calorie-dense and very high in Vitamin A. Used daily across multiple training sessions, liver must stay within 5% of the total daily diet across all meals and treats combined. Chronic excess Vitamin A causes hypervitaminosis A, bone pain, stiffness and in severe cases, joint fusion.
How to Transition Your Puppy to Raw Food
Can puppies eat a raw food diet from day one? Yes, but how you introduce it matters. A cold turkey transition works well for most puppies: fast overnight, then introduce the first raw meal in the morning. For puppies with sensitive stomachs, gradual phasing is more reliable.
Over seven days, move from 15% raw and 85% previous food on day one, up to 100% raw by day seven. Progress through 25% on day two, 35% on day three, 50/50 on day four, 75% raw on day five, and full raw from day seven. Minor stool softening in the first three days is normal. It typically resolves by day four as the gut microbiome adjusts.
Pro Tip: Use a single protein, chicken or rabbit, for the first two full weeks on raw. Introducing multiple proteins at once makes it impossible to identify the cause if digestive issues arise. Add a new protein every five to seven days once the gut has settled.
Conclusion
Understanding how much raw food to feed a puppy is a weekly practice, not a one-time figure. Weigh your puppy every seven days, recalculate the portion, maintain 17% raw edible bone at all times, and let the rib test and stool quality confirm whether the balance is right.
Done correctly, raw feeding gives your puppy one of the most nutritionally appropriate diets available. The goal is never rapid growth; it is steady, lean development that builds a structurally sound dog built to last.
FAQ _ People Also Ask
How much raw food should I feed my puppy per day?
Feed 8 to m10% of your puppy’s current body weight daily at 7 to 10 weeks, split across four meals. Weigh every 7 days and recalculate puppy growth is non-linear and last week’s portion is already outdated. Reduce progressively to 2–3% at adult maintenance.
Is raw food good for puppies?
Raw food is good for puppies when it is nutritionally complete. Benefits include better dental health, lean-controlled growth, improved stool quality, and a stronger immune foundation. The only risk is from unbalanced diets, particularly those missing raw edible bone or lacking iodine, zinc, DHA, and Vitamin D.
When can puppies have raw food?
Puppies can start raw food from 3 to 4 weeks as a weaning supplement. Most are ready for a complete raw diet by 7 to 8 weeks. A puppy arriving at your home at 8 weeks can start raw immediately use a single protein for the first two weeks before introducing variety.
Can puppies eat raw dog food bought from shops?
Yes, commercially prepared complete raw food is the safest starting point. Choose products labelled ‘complete and balanced’ that have been independently tested. HPP raw reduces pathogen risk without heat. Avoid anything labelled ‘complementary only’ as these require additional nutritional balancing.
Can puppies eat a raw food diet alongside kibble?
Not recommended in the same meal. Raw digests faster than kibble, and combining both causes digestive inconsistency. Separate them by at least 4 to 6 hours, or follow the 7-day gradual phasing method to switch fully to raw.
What is the difference between BARF and PMR for puppies?
PMR is strictly animal-based muscle meat, bone, and organs with no plant material. BARF includes 7 to 11% plant matter. Both models use 17% raw edible bone for puppies. PMR proponents argue dogs have no need for plant material; BARF proponents argue it adds fibre and phytonutrients that organ meat alone cannot provide.
What happens if I feed too little bone?
Insufficient bone causes Nutritional Secondary Hyperparathyroidism, the body dissolves its own skeleton to maintain blood calcium. Signs include bone pain, inability to stand, and pathological fractures. Published case series document this in puppies fed exclusively boneless raw meat within months of starting the diet.
Do I need supplements on a raw puppy diet?
Three are consistently recommended: oily fish or fish oil for EPA/DHA; kelp-based iodine for thyroid function; and Vitamin D3 if oily fish is not fed at least twice weekly. Dogs cannot make Vitamin D from sunlight; it must come from the diet without exception.
