Raw Feeding Puppies UK: Beginner's Guide

Raw feeding puppies is one of the best decisions you can make for their long-term health and development. Done correctly, puppies fed raw diets from a young age tend to have stronger immune systems, better dental health, clearer skin, and more stable energy levels than their kibble-fed counterparts. But puppy raw feeding does require attention to detail—growth is rapid, nutritional needs are higher, and the margins for error are smaller. This comprehensive guide walks you through everything you need to know. For detailed ratio guidance, see our comprehensive portion guide.

When Can Puppies Start Eating Raw Food?

The timing depends on your pup's situation:

Puppies Still with Mother (3-4 Weeks)

You can introduce small amounts of raw food from about 3-4 weeks whilst puppies are still nursing. At this stage, mum is still providing crucial antibodies and nutrition through milk, but puppies are increasingly interested in solid food. Introduce minced raw meat in tiny portions (a tablespoon at a time) alongside nursing.

Newly Weaned Puppies (6-8 Weeks)

Most puppies are fully weaned and ready for raw feeding around 8 weeks old. If you're bringing home a new puppy at 8-12 weeks, this is the ideal time to establish raw feeding. Even if they've had kibble or wet food from their breeder, switching to raw is straightforward at this age.

If you're adopting or acquiring a puppy that's already older (12+ weeks), they can transition to raw without difficulty, though you may want to do it gradually over 7-10 days to avoid digestive upset. Learn more from The Kennel Club's puppy guidance.

The Sliding Scale: How Much to Feed by Age

Puppy feeding is dramatically different from adult feeding. Puppies are growing rapidly and have much higher caloric and nutritional demands. This is where the "sliding scale" comes in—the percentage of body weight needed decreases as your puppy grows.

Why Such High Percentages?

An 8-week-old puppy's metabolism is vastly different from an adult dog's. They're not just maintaining their current body—they're building bone, muscle, fur, organ tissue, and brain development, all simultaneously. A growing puppy can burn 2-3 times more calories per kilogram of body weight than an adult dog.

As your puppy grows, their absolute food consumption increases (because they're getting heavier), but the percentage of body weight needed decreases. By adulthood, they'll need just 2-2.5% of body weight, but they'll be eating far more in grams because they're much larger.

Practical Feeding Examples by Age

Let's make this concrete with real examples for a medium-breed puppy (Cocker Spaniel, predicted adult weight 25kg):

Starting Proteins: Introduce Gradually

One of the most common raw feeding mistakes with puppies is introducing too much variety too quickly. A young puppy's digestive system is still establishing its microbiome and needs time to adapt to raw feeding. Introduce proteins one at a time, waiting 5-7 days between introducing new proteins to monitor for sensitivities.

Recommended Protein Introduction Order

Bone Content for Growing Puppies

Bones are crucial for puppies—they're not just food, they're building materials for growing skeletons. However, bone content needs careful management in puppies.

The Right Bone Content

Most raw feeding guidance recommends 10-15% bone content for puppies (slightly higher than the typical 10% for adults). This provides adequate calcium and phosphorus without excessive mineral loading on developing kidneys. Raw meaty bones like chicken wings, chicken necks, and lamb ribs are ideal.

Calcium to Phosphorus Ratio

This is critical for puppies. The calcium-to-phosphorus ratio should be roughly 1.2:1. Whole prey naturally provides this balance, but if you're feeding individual components, monitor carefully. Too much phosphorus relative to calcium interferes with bone development. Too much calcium can cause joint and bone problems, especially in large-breed puppies.

Bone Types to Avoid for Young Puppies

• Large weight-bearing bones (e.g., femurs, marrow bones) are too hard for young puppies and risk broken teeth
• Cooked bones of any kind—they splinter and are dangerous
• Very small bones that could be swallowed whole without grinding

Feeding Frequency by Age

As puppies grow, they can handle larger meals less frequently. This is crucial for owners—fewer meals means less preparation and monitoring.

Note: Two meals per day is recommended for most dogs to prevent bloat and promote stable digestion, even in adulthood. For more on managing raw feeding transition, see our transition guide.

Common Puppy Raw Feeding Mistakes to Avoid

1. Introducing Too Much Variety Too Quickly

Feeding chicken, beef, pork, and turkey all within the first two weeks overwhelms a young digestive system. Stick with one protein for 5-7 days before introducing the next. This lets you identify any sensitivities clearly.

2. Neglecting Organ Meat

Organ meats are essential for puppies—they're nutrient-dense and crucial for development. Aim for 10% organ meat overall (5% liver, 5% other organs). If you skip this, you're missing vital nutrients like vitamin A, iron, and taurine.

3. Wrong Bone Content or Types

Oversized bones can damage developing teeth. Undersized bones can be swallowed whole. Aim for soft raw bones (chicken wings, necks, ribs) that are appropriately sized for your puppy's mouth. Ground raw bones or finely minced bone works well for very young puppies.

4. Not Monitoring Growth Carefully

Puppies grow rapidly, and portion needs change frequently. Weigh your puppy every 1-2 weeks for the first 6 months and adjust portions accordingly. A puppy that's too thin or too fat sets them up for health problems throughout life.

5. Feeding Only Muscle Meat

Some new raw feeders feed almost exclusively muscle meat because it's easier to source and less "weird" than organs. But organ meat is nutritionally irreplaceable. If your puppy gets mostly muscle meat, they're missing crucial micronutrients.

Monitoring Puppy Growth and Body Condition

Unlike adults, puppies are constantly changing. You need to assess and adjust more frequently.

Body Condition Scoring for Puppies

Puppies should have visible ribs when looked at from above, but not excessively prominent. When you run your hand along their sides, you should feel the ribs easily without pressing hard, but not see them starkly. This is healthy body condition for growth—slightly more visible than adults. Consult RSPCA guidance on body condition scoring.

Signs Your Puppy Is Getting the Right Amount

• Steady growth week to week (consult your vet for breed-specific growth curves)
• Shiny coat and bright eyes
• Firm stools (may be slightly softer than kibble-fed puppies, but not runny)
• Good energy and enthusiasm
• Muscles are developing visibly

Large Breed vs Small Breed Puppies

Large and giant breed puppies need special consideration. They grow for much longer (up to 18-24 months) and their calcium and phosphorus requirements are more critical. Too much food—or specifically too much calcium—in the first year can cause orthopedic problems like hip dysplasia and elbow dysplasia.

Large Breed Considerations

Large breed puppies should grow slowly and steadily rather than rapidly. Feed at the lower end of the percentage range for your puppy's age. Monitor bone content carefully—aim for exactly 10-12% rather than experimenting. Work with your vet to ensure calcium-phosphorus ratios are ideal.

Many large breed puppy raw feeders recommend adding calcium supplementation (through finely ground eggshell or specific supplements) to maintain optimal ratios. Small breed puppies typically don't need this if fed proper ratios.

When to Switch to Adult Feeding Percentages

The transition happens gradually and varies by breed:

• Small breeds: Around 9-10 months of age
• Medium breeds: Around 12 months of age
• Large breeds: Around 12-15 months of age
• Giant breeds: Around 18-24 months of age

Rather than switching abruptly, gradually reduce percentages over 2-4 weeks. If your 10-month-old puppy is currently eating 3.5% and should transition to 2.5%, reduce gradually—3.2%, then 2.8%, then 2.5%—and monitor body condition carefully.
