Weaning Puppies Onto Raw: A Safe UK Guide for 2026

When To Start Weaning Puppies Onto Raw

Weaning puppies onto raw food typically begins between 3 and 4 weeks of age, when puppies start showing interest in their mother’s meals and their first teeth break through. The window for full transition runs from around week 3 to week 7 or 8, by which point pups should be eating four small raw meals a day independently.

If you’re an owner collecting an 8-week-old pup that’s already weaned onto kibble, the principles still apply — you’ll simply use a slower, gentler transition rather than starting from milk. The Pet Food Manufacturers’ Association recommends prioritising age-appropriate nutrition through every life stage, and a properly balanced raw diet meets those needs from the very first solid meal.

Why Raw From The Start Matters

Puppies fed a biologically appropriate diet from weaning enjoy a smoother microbiome transition than those switched from kibble months later. Their immature digestive systems learn to handle natural proteins, fats and bone without the inflammation many owners later associate with kibble. Studies cited by the British Veterinary Association highlight how early diet shapes lifelong gut health, joint development and immune function.

Raw fed pups also tend to develop strong jaw muscles, cleaner teeth and steadier growth rates — particularly important for large and giant breeds where rapid weight gain on calorie-dense kibble is linked to skeletal problems. If you’re considering the BARF approach instead of PMR, our complete BARF guide explains the differences and how each model suits puppies. Weaning puppies onto raw also sets up taste preferences early — many kibble-only dogs later refuse raw, whereas pups raised on it accept new proteins enthusiastically for life.

7 Easy Steps for Weaning Puppies Onto Raw

This is the proven sequence UK breeders use for weaning puppies onto raw safely over four weeks. Stick to one protein at a time and don’t rush — pups will tell you when they’re ready for the next stage.

1. 1. Days 1–3 (week 3): Offer a teaspoon of finely minced raw chicken breast, blended into a smooth slurry with warm water. Place it on a flat plate so multiple pups can investigate.
2. 2. Days 4–7: Increase the slurry to one tablespoon per pup, twice a day. Add a pinch of finely ground egg yolk for fat and choline.
3. 3. Week 4: Move to slightly chunkier minced chicken with finely ground bone (chicken wings minced through a grinder work well). Offer four small meals a day.
4. 4. Week 5: Add a second protein — minced turkey or duck — on alternate days. Introduce a small amount of organ meat (around 5% liver) for the first time.
5. 5. Week 6: Begin offering soft edible bone like minced chicken necks. Start to coarsen the mince so pups practise chewing.
6. 6. Week 7: Move to chunked meat rather than mince. Add a red meat protein such as minced lamb or beef. Total daily food should sit at 8–10% of bodyweight.
7. 7. Week 8 onwards: Fully weaned. Continue four meals a day until 12 weeks, then drop to three. Mother is no longer needed nutritionally.

Building a Balanced Raw Meal for Weaning Puppies

When weaning puppies onto raw, every meal still follows the same 80/10/10 prey model ratios as adults — but with a slightly higher bone content (12–15%) to support growth, and care to keep liver under 5% of the meal in the early weeks. Here’s how a balanced meal breaks down:

Portion Sizes During Weaning

Puppies eat a far higher percentage of bodyweight than adults — typically 8–10% during weaning, tapering down as they grow. Always split the daily total across four meals to keep blood sugar steady. The table below shows approximate daily totals for healthy pups.

Weigh weekly. Adjust portions by ±10% based on body condition — you should feel ribs easily without seeing them. When weaning puppies onto raw, portion accuracy matters far more than at any later life stage, so don’t eyeball it.

Safe First Proteins When Weaning Puppies Onto Raw

Not every protein is equal at this delicate stage. The safest first proteins for weaning puppies onto raw are lean, low-fat poultry that’s easy to mince finely. Save richer proteins for week 5 or later, once digestion has settled.

• • Chicken breast (week 3): The textbook starter. Cheap, low-fat, easy to source from any UK supermarket. Around £4–£6 per kg.
• • Turkey mince (week 4): Slightly leaner than chicken, gentle on tummies. Look for plain mince with no added water.
• • Duck (week 5): A nutrient-rich novel protein. Richer in iron and zinc — ideal as a second protein.
• • Lamb (week 6): The first red meat in the rotation. Higher fat, so build up slowly.
• • Beef (week 7): Lean beef mince introduces another red protein. Avoid fatty cuts until pups are over 12 weeks.

Avoid pork in the first month unless it’s pre-frozen for three weeks (UK guidance on Aujeszky’s disease, see the Food Standards Agency). Also hold off on oily fish like salmon and mackerel until 8 weeks, when whole sardines become a brilliant omega-3 addition.

Common Mistakes When Weaning Puppies Onto Raw

Most issues people report when weaning puppies onto raw come down to a handful of avoidable errors. Recognise them early and the whole transition becomes much smoother.

• • Introducing too many proteins at once — start with chicken alone. Add a new protein only every 5–7 days.
• • Skipping bone or grinding it wrong — puppies on bone-less diets risk calcium deficiency within weeks. Always include 12–15% ground bone.
• • Feeding cold from the fridge — pups eat best at room temperature. Take meals out 20 minutes early or warm with a splash of hot water.
• • Over-feeding fat — duck legs and lamb mince contain more fat than chicken. Trim visible fat in the first month.
• • Free-feeding all day — leaving raw food out for hours grows bacteria and removes meal structure. Pups should finish each meal in 5–10 minutes.
• • Forgetting to weigh — pups outgrow portions every week. A 5kg lab pup at 8 weeks may need 700g a day by 10 weeks.

Hygiene, Storage & Safety

Weaning puppies onto raw means raw meat in the kitchen — and pups are messier than adult dogs. The PDSA emphasises the same kitchen hygiene rules whether you’re handling raw food for humans or pets. Apply common-sense practice:

• • Defrost meals in the fridge for 12–24 hours. Never refreeze fully thawed raw meat.
• • Use stainless steel bowls or ceramic — easy to disinfect after each meal.
• • Wash hands and surfaces with hot soapy water immediately after preparing meals.
• • Keep a dedicated chopping board for raw pet food, ideally a different colour.
• • Portion meals into freezer-safe tubs in advance — a fortnight’s worth saves time and money.

Vulnerable adults, young children or immunocompromised household members should not handle raw pet food directly.

Frequently Asked Questions

At what age should I start weaning puppies onto raw?

Begin at 3 to 4 weeks of age, when puppies start showing interest in solid food and their first teeth emerge. Full transition should be complete by 7 to 8 weeks.

Can I switch an 8-week-old kibble-fed puppy to raw?

Yes. Use a slow 7–10 day transition rather than a sudden swap. Start with 25% raw mixed with 75% kibble, increasing the raw portion every two days. Our transition guide covers the full process.

How much should a puppy eat when weaning onto raw?

Aim for 8–10% of current bodyweight per day, split across four meals. A 5kg pup needs roughly 400g daily. Reweigh weekly and adjust.

Is weaning puppies onto raw safe for large breeds?

Yes — and often safer than calorie-dense kibble that drives rapid growth. Aim for steady, lean development by keeping calcium at 12–15% bone content and avoiding over-feeding fat.

Do raw fed puppies need supplements?

A balanced 80/10/10 raw diet with whole eggs and occasional oily fish meets nearly all needs when weaning puppies onto raw. Many breeders add a small amount of green-lipped mussel powder for joints once pups are 12 weeks old.
