Bringing a new puppy home is one of the most exciting experiences for any dog owner, but it also comes with a great deal of responsibility. One of the biggest questions new puppy parents ask is: how much should I feed my puppy? Getting your puppy’s nutrition right during those crucial first months can have a lasting impact on their growth, development, and long-term health.

In this complete puppy feeding guide for UK dog owners, we’ll walk you through everything you need to know about feeding your growing puppy — from how many meals per day they need at each age stage, to portion sizes for small, medium, and large breeds, and how to spot the signs that you’re feeding too much or too little. Whether you’ve just brought home a tiny Chihuahua puppy or a bouncy Labrador, this guide covers it all.

Understanding Your Puppy’s Nutritional Needs

Before we dive into specific feeding amounts, it’s important to understand why puppies have such different nutritional requirements compared to adult dogs. Puppies grow at an extraordinary rate during their first year — some breeds can multiply their birth weight by up to 70 times by the time they reach adulthood. That kind of rapid development demands a carefully balanced diet.

According to the European Pet Food Industry Federation (FEDIAF), puppies require significantly higher levels of protein, fat, vitamins, and minerals than adult dogs. These guidelines are the gold standard for pet food manufacturers across Europe and are backed by extensive scientific research into canine nutrition.

Key Nutrients Every Puppy Needs

Protein

Protein is the building block of your puppy’s growing body. It supports the development of muscles, organs, skin, coat, and the immune system. The British Veterinary Association (BVA) recommends that puppy food contains a minimum of 25-30% protein from high-quality animal sources such as chicken, lamb, fish, or turkey. Look for named meat proteins at the top of the ingredient list rather than generic “meat meal” or animal derivatives.

Fat

Fat provides the concentrated energy that puppies need to fuel their rapid growth and boundless activity. Puppy food should typically contain between 12-18% fat. Fat also delivers essential fatty acids, including omega-3 and omega-6, which are crucial for brain development, healthy skin, and a glossy coat. DHA (docosahexaenoic acid), an omega-3 fatty acid found in fish oil, is particularly important for cognitive and visual development in young puppies.

Calcium and Phosphorus

These two minerals work together to build strong bones and teeth. Getting the balance right is critical — too little calcium can lead to skeletal problems, whilst too much can cause abnormal bone growth, particularly in large breed puppies. FEDIAF guidelines specify precise calcium-to-phosphorus ratios for puppy food, which is why feeding a specially formulated puppy food rather than adult food is so important. Large breed puppy foods are specifically designed with controlled calcium levels to support steady, healthy bone development.

DHA (Docosahexaenoic Acid)

DHA is an omega-3 fatty acid that plays a vital role in your puppy’s brain and eye development. Puppies whose mothers received adequate DHA during pregnancy, and who continue to receive it through their diet, show improved trainability, better problem-solving abilities, and enhanced visual development. Quality puppy foods often include fish oil or fish meal as a natural source of DHA.

Vitamins and Minerals

Puppies need a full spectrum of vitamins and minerals to support their developing immune systems, growing bones, and overall health. Key vitamins include vitamin A for vision and immune function, vitamin D for calcium absorption, vitamin E as an antioxidant, and B vitamins for energy metabolism. A “complete” puppy food will contain all of these in the correct proportions.

How Much Should You Feed Your Puppy? – By Age

One of the most common mistakes new puppy owners make is applying a one-size-fits-all approach to feeding. In reality, a puppy’s nutritional needs change dramatically as they grow. A six-week-old Chihuahua has vastly different requirements from a six-month-old German Shepherd. Below, we break down exactly how much to feed your puppy at each stage of their development.

8-12 Weeks (Newly Weaned)

This is the age at which most puppies go to their new homes. They have recently been weaned from their mother’s milk and are adjusting to solid food. At this stage, their small stomachs mean they need frequent, smaller meals to maintain steady energy levels and blood sugar.

Feeding Schedule

  • Meals per day: 4 meals spread evenly throughout the day
  • Example times: 7:00am, 11:00am, 3:00pm, 7:00pm

Daily Amount Guide

  • Small breeds (e.g., Chihuahua, Pomeranian): 50-100g per day
  • Medium breeds (e.g., Cocker Spaniel, Border Collie): 100-200g per day
  • Large breeds (e.g., Labrador, Golden Retriever): 200-350g per day

Nutritional Focus

At this stage, your puppy is adjusting to life away from their mother. Consistency is key — feed the same food they were eating at the breeder for at least the first week to avoid digestive upset. If you plan to change their food, follow a gradual transition guide over 7-10 days. The food should be calorie-dense and nutrient-rich to support their initial growth spurt.

Tips for 8-12 Week Old Puppies

  • Always have fresh water available — puppies dehydrate quickly
  • Keep meal times calm — no excitement or competition around the food bowl
  • Soften kibble slightly with warm water if your puppy is struggling to chew
  • Monitor weight gain weekly — puppies should gain weight steadily but not excessively
  • Never leave food out between meals at this age (no free-feeding)

3-4 Months

At three to four months, your puppy is becoming more confident, active, and curious about the world. Their growth rate is at its peak, and they need plenty of fuel to support their increasing activity levels and ongoing physical development.

Feeding Schedule

  • Meals per day: 3 meals per day
  • Example times: 7:00am, 1:00pm, 7:00pm

Daily Amount Guide

  • Small breeds: 70-130g per day
  • Medium breeds: 150-250g per day
  • Large breeds: 250-400g per day

Nutritional Focus

This is a period of rapid growth, particularly for medium and large breeds. Protein and fat requirements remain high. Your puppy’s immune system is also maturing, so foods containing antioxidants (such as vitamin E, vitamin C, and selenium) are beneficial. This is also the age at which many puppies begin their vaccination programme, so supporting immune health through nutrition is especially important.

Tips for 3-4 Month Old Puppies

  • Begin establishing a consistent daily routine — puppies thrive on predictability
  • Start using meal times as training opportunities — ask for a sit before placing the bowl down
  • If your puppy seems constantly hungry between meals, speak to your vet before increasing portions
  • Be mindful of foods that are toxic to puppies — well-meaning family members may offer unsuitable treats

4-6 Months

Between four and six months, your puppy is entering their adolescent phase. Small breeds may already be approaching their adult size, whilst large breeds are still in the early stages of their growth journey. This is a period where overfeeding can become a real risk, as your puppy’s rapid growth begins to slow slightly but their appetite may remain enormous.

Feeding Schedule

  • Meals per day: 3 meals per day (beginning to transition towards 2 meals for some breeds)
  • Example times: 7:00am, 1:00pm, 7:00pm or 7:00am, 6:00pm

Daily Amount Guide

  • Small breeds: 80-140g per day
  • Medium breeds: 180-300g per day
  • Large breeds: 300-450g per day

Nutritional Focus

Bone development is particularly critical at this stage, especially for larger breeds. Ensure you’re feeding a large breed-specific puppy food if you have a dog expected to weigh over 25kg as an adult. These foods have carefully controlled calcium and phosphorus levels to prevent developmental orthopaedic diseases. Joint-supporting nutrients like glucosamine and chondroitin are also valuable at this age.

Tips for 4-6 Month Old Puppies

  • Start reducing from 3 to 2 meals per day if your puppy seems comfortable with the change
  • Weigh your puppy regularly and compare against breed growth charts
  • Be firm with the family about table scraps — this is when bad habits form
  • Consider whether your puppy’s food still meets their needs — some fast-growing breeds may benefit from moving onto a different formula

6-9 Months

By six to nine months, most puppies are well on their way to being young adults. Their growth rate is slowing down, but they’re still developing muscle, bone density, and brain function. This is also the age when many puppies are neutered or spayed, which can affect their metabolism and calorie requirements.

Feeding Schedule

  • Meals per day: 2 meals per day
  • Example times: 7:00am, 6:00pm

Daily Amount Guide

  • Small breeds: 70-120g per day (approaching adult portions)
  • Medium breeds: 200-350g per day
  • Large breeds: 350-500g per day

Nutritional Focus

As growth begins to plateau, particularly for small and medium breeds, calorie requirements may start to decrease. This is the time to be extra vigilant about portion control — many puppy owners continue feeding puppy-sized portions even as their dog’s growth slows, leading to unwanted weight gain. If your puppy has been neutered, their calorie needs may drop by up to 25%, so adjust portions accordingly.

Tips for 6-9 Month Old Puppies

  • Transition firmly to a 2-meal-per-day schedule if you haven’t already
  • Regularly assess your puppy’s body condition — you should be able to feel (but not see) their ribs
  • If your puppy has been neutered, speak to your vet about adjusting their food intake
  • Large breeds at this stage should still be on puppy food, but smaller breeds may be ready to transition to adult food

9-12 Months

Most small and medium breed puppies will reach their full adult size by around 9-12 months of age. Large breeds may still have several months of growing left. At this stage, the transition from puppy food to adult food begins for most dogs, and feeding amounts need to be carefully managed.

Feeding Schedule

  • Meals per day: 2 meals per day
  • Example times: 7:00am, 6:00pm

Daily Amount Guide

  • Small breeds: 60-110g per day (now on adult food)
  • Medium breeds: 200-350g per day (transitioning to adult food)
  • Large breeds: 350-550g per day (still on puppy food)

Nutritional Focus

The key focus at this stage is the transition from puppy to adult food. This should be done gradually over 7-10 days to avoid digestive upset. Start by replacing 25% of the puppy food with adult food on days 1-3, then 50% on days 4-6, 75% on days 7-9, and fully adult food from day 10 onwards. Always choose a high-quality adult dry dog food that’s labelled as “complete” to ensure it meets all nutritional requirements.

Tips for 9-12 Month Old Puppies

  • Don’t rush the transition — your puppy’s digestive system needs time to adjust
  • Monitor their stool quality during the transition period
  • Large and giant breeds should stay on puppy food until 12-24 months
  • This is a good time to reassess treats and extras — they should make up no more than 10% of daily calories

12+ Months (Transition to Adult Feeding)

By twelve months, most dogs are considered young adults and should be fully transitioned onto an appropriate adult food. The exception is giant breeds (such as Great Danes, Mastiffs, and Saint Bernards), which may continue growing until 18-24 months and should remain on a growth formula for longer.

Feeding Schedule

  • Meals per day: 2 meals per day (standard for most adult dogs)
  • Example times: 7:00am, 6:00pm

Daily Amount Guide

  • Small breeds (up to 10kg adult weight): 50-110g per day
  • Medium breeds (10-25kg adult weight): 180-350g per day
  • Large breeds (25kg+ adult weight): 300-550g per day

Nutritional Focus

Adult dogs need a different nutritional profile compared to puppies — particularly lower calorie density, controlled protein levels, and balanced minerals. Choose an adult food that matches your dog’s size, activity level, and any specific health needs. If you’re unsure which food is best, our puppy food reviews include recommendations for foods that work well during the transition period.

Puppy Feeding Chart: Quick Reference

The following puppy feeding chart provides a quick overview of how much to feed your puppy based on their age and breed size. These amounts are approximate guidelines for complete dry kibble — always check the specific feeding guide on your puppy food packaging, as calorie content varies between brands.

Age Meals per Day Daily Amount (Small Breed up to 10kg) Daily Amount (Medium Breed 10-25kg) Daily Amount (Large Breed 25kg+)
8-12 Weeks 4 50-100g 100-200g 200-350g
3-4 Months 3 70-130g 150-250g 250-400g
4-6 Months 3 80-140g 180-300g 300-450g
6-9 Months 2 70-120g 200-350g 350-500g
9-12 Months 2 60-110g 200-350g 350-550g
12+ Months 2 50-110g 180-350g 300-550g

Important: These are general guidelines. Always refer to the feeding guide on your specific puppy food packaging and consult your vet for personalised advice, especially if your puppy has specific health requirements.

How to Calculate the Right Portion Size

The feeding chart above gives you a solid starting point, but every puppy is unique. Here’s how to fine-tune your puppy’s portions for their individual needs.

Check the Feeding Guide on the Packaging

All reputable puppy food brands include a feeding guide on the packaging based on your puppy’s current weight and expected adult weight. This is your best starting point. However, these guides are general estimates — you should always adjust based on your individual puppy’s body condition and activity level.

Use the Body Condition Score (BCS)

The PDSA recommends regularly assessing your puppy’s body condition using a simple 9-point scale. Here’s what to look for:

  • Ideal (Score 4-5 out of 9): You can feel your puppy’s ribs easily without pressing hard, but they’re not visible. There’s a visible waist when viewed from above, and the belly tucks up when viewed from the side.
  • Underweight (Score 1-3): Ribs, spine, and hip bones are easily visible. No discernible waist. The belly tucks up excessively.
  • Overweight (Score 6-9): Ribs are difficult to feel under a layer of fat. No visible waist. The belly may sag rather than tuck up.

If your puppy scores above or below the ideal range, adjust their daily food amount by 10% and reassess after two weeks.

Adjust for Activity Level

A highly active puppy — one that goes on long walks, plays vigorously, or attends training classes — will need more calories than a relatively sedentary puppy. Conversely, a puppy recovering from illness or surgery may need reduced portions temporarily. Work with your vet to determine the right calorie intake for your puppy’s specific lifestyle.

Factor in Treats and Extras

According to the RSPCA, treats should make up no more than 10% of your puppy’s daily calorie intake. If you’re giving your puppy training treats, dental chews, or other extras throughout the day, remember to reduce their main meal portions accordingly. Those little training treats add up surprisingly quickly!

Best Feeding Practices for Puppies

Getting the right amount of food is only part of the equation. How you feed your puppy is just as important. Follow these best feeding practices to set your puppy up for a lifetime of healthy eating habits.

Establish a Consistent Routine

Dogs thrive on routine, and puppies are no exception. Feed your puppy at the same times every day, in the same location. This predictability helps with house training (puppies typically need to toilet shortly after eating), reduces anxiety, and helps regulate their digestive system.

Use Mealtimes for Training

Meal times are an excellent training opportunity. Ask your puppy to sit and wait calmly before placing their bowl down. This reinforces basic obedience and helps prevent food-related behaviour problems such as resource guarding or jumping up at the bowl.

Always Provide Fresh Water

Your puppy should have access to clean, fresh water at all times. Puppies need more water per kilogram of body weight than adult dogs — roughly 50-60ml per kg of body weight per day, increasing in hot weather or after exercise. Wash and refill their water bowl at least twice daily.

Keep Bowls Clean

Bacteria can build up quickly in food and water bowls, particularly in warm weather. Wash your puppy’s bowls daily with hot soapy water or run them through the dishwasher. Stainless steel or ceramic bowls are easier to keep hygienic than plastic ones, which can develop scratches that harbour bacteria.

Avoid Free-Feeding

Free-feeding (leaving food out all day) is generally not recommended for puppies. It makes it difficult to monitor how much your puppy is eating, can lead to overeating and obesity, may contribute to picky eating habits, and makes house training more challenging. Instead, offer measured portions at set times and remove the bowl after 15-20 minutes if your puppy hasn’t finished.

Feed in a Quiet Location

Choose a calm, quiet spot for your puppy’s meals, away from high-traffic areas in your home. If you have other dogs, feed them separately to prevent competition, stress, or food aggression. Children should be taught not to disturb the puppy while they’re eating.

Signs You’re Overfeeding or Underfeeding Your Puppy

Getting portion sizes right isn’t always straightforward, especially when your puppy seems permanently hungry (as most puppies do!). Here are the key signs to watch out for.

Signs of Overfeeding

  • Excessive weight gain: Your puppy is gaining weight faster than expected for their breed
  • No visible waist: When viewed from above, your puppy’s body appears barrel-shaped
  • Difficulty feeling ribs: You have to press firmly to feel their ribcage
  • Loose, frequent stools: More food than their digestive system can process
  • Reduced energy levels: Paradoxically, overfed puppies can become sluggish
  • Joint stress: In large breeds, excess weight puts undue stress on developing joints, potentially causing long-term problems

The Blue Cross warns that puppyhood obesity significantly increases the risk of joint problems, diabetes, and heart disease later in life. Prevention is far easier than treatment.

Signs of Underfeeding

  • Visible ribs, spine, and hip bones: These should not be prominently visible in a healthy puppy
  • Low energy: Your puppy seems lethargic or disinterested in play
  • Poor coat condition: Dull, dry, or flaky skin and coat can indicate nutritional deficiency
  • Slow growth: Your puppy isn’t meeting expected weight milestones for their breed
  • Excessive hunger: Your puppy is constantly scavenging, stealing food, or acting desperately hungry at meal times
  • Stool issues: Small, hard stools or very infrequent bowel movements

If you notice any of these signs, adjust the portion size by 10-15% and monitor for improvement over the following two weeks. If you’re unsure, always consult your vet.

Choosing the Right Puppy Food for Your Dog’s Age

With so many options available, choosing the right puppy food can feel overwhelming. Here are the key factors to consider:

Always Choose “Complete” Food

In the UK, pet foods labelled as “complete” must meet all the nutritional requirements for the stated life stage as defined by FEDIAF guidelines. “Complementary” foods, on the other hand, are designed to be fed alongside other foods and do not contain the full range of nutrients your puppy needs. Always check the label — if it doesn’t say “complete,” it shouldn’t be your puppy’s sole food source.

Consider Breed Size

Many premium brands now offer size-specific puppy foods. Small breed puppy foods feature smaller kibble sizes for tiny mouths and are often more calorie-dense to match small dogs’ faster metabolisms. Large breed puppy foods have controlled calcium and phosphorus levels, added joint-supporting ingredients, and are designed to support slower, steadier growth.

Dry vs Wet Food

Both dry kibble and wet food can form the basis of a healthy puppy diet, and many owners choose to feed a combination of both. Wet puppy food is often more palatable and provides additional hydration, whilst dry kibble is more convenient, better for dental health, and typically more economical. If you mix wet and dry food, be careful not to overfeed — calculate the combined calorie content.

Grain-Free Considerations

Grain-free puppy foods have become increasingly popular, but it’s important to be aware of the ongoing research into a potential link between grain-free diets and a heart condition called dilated cardiomyopathy (DCM) in dogs. Unless your vet has specifically recommended a grain-free diet due to a diagnosed allergy, you may wish to choose a grain-inclusive food. Read our full analysis on whether grain-free food is good for puppies to make an informed decision.

Special Considerations

Large and Giant Breed Puppies

Large breed puppies (those expected to weigh over 25kg as adults, such as Labradors, Golden Retrievers, and Rottweilers) and giant breed puppies (over 45kg, such as Great Danes and Mastiffs) have very specific nutritional requirements. The most critical consideration is controlled growth rate.

Overfeeding large breed puppies — particularly feeding food with excessive calcium, phosphorus, or vitamin D — can lead to developmental orthopaedic diseases (DOD) including osteochondrosis, hypertrophic osteodystrophy (HOD), and panosteitis. These painful conditions can have lifelong consequences for your dog’s mobility and quality of life.

Key recommendations for large and giant breed puppies include:

  • Always choose a food specifically formulated for large breed puppies
  • Never supplement with calcium or vitamin D unless directed by your vet
  • Keep your puppy lean — slightly underweight is far preferable to slightly overweight
  • Avoid strenuous exercise until their growth plates close (typically 12-18 months)
  • Giant breeds may need to stay on puppy food until 18-24 months of age

Small and Toy Breed Puppies

Small and toy breed puppies (under 10kg as adults, such as Pomeranians, Yorkshire Terriers, and Chihuahuas) face their own unique challenges. Their tiny stomachs mean they can’t eat large quantities at once, yet their fast metabolisms require frequent, energy-dense meals. Small breed puppies are also more susceptible to hypoglycaemia (low blood sugar), which can be dangerous if meals are missed or delayed.

Key recommendations for small and toy breed puppies include:

  • Choose a small breed-specific puppy food with smaller kibble and higher calorie density
  • Never skip meals — feed at consistent times and ensure they eat before long periods of activity
  • Monitor closely for signs of low blood sugar: lethargy, weakness, trembling, or confusion
  • Keep a small amount of honey or glucose solution on hand as an emergency energy boost
  • Small breeds typically reach adult size faster and can transition to adult food around 8-10 months

Puppies with Sensitive Stomachs

Some puppies are prone to digestive upset, which may manifest as loose stools, flatulence, vomiting, or reluctance to eat. If your puppy consistently experiences digestive issues, consider the following:

  • Choose a puppy food with a limited number of ingredients
  • Look for foods containing prebiotics and probiotics to support gut health
  • Avoid foods with artificial colours, flavours, or preservatives
  • Always transition foods gradually over 7-10 days
  • If problems persist, consult your vet — your puppy may have a food allergy or intolerance that requires a specific diet

Frequently Asked Questions (FAQ)

How many times a day should I feed my puppy?

The number of meals depends on your puppy’s age. From 8-12 weeks, feed 4 meals per day. At 3-6 months, reduce to 3 meals per day. From 6 months onwards, most puppies can be fed 2 meals per day. Always space meals evenly throughout the day and try to keep to the same times each day. Consistent feeding times help with house training and support healthy digestion.

Can I free-feed my puppy?

We strongly recommend against free-feeding (leaving food available all day). Free-feeding makes it very difficult to monitor how much your puppy is eating, increases the risk of overeating and obesity, can lead to picky eating habits, and makes house training much harder because you can’t predict when they’ll need the toilet. Instead, offer measured portions at set times and remove the bowl after 15-20 minutes.

How do I know if my puppy is eating enough?

The best way to tell is by regularly assessing their body condition score. A healthy puppy should have a visible waist when viewed from above, and you should be able to feel their ribs easily without pressing hard, but the ribs shouldn’t be visibly protruding. Your puppy should also have good energy levels, a glossy coat, and produce well-formed stools. If in doubt, ask your vet to assess your puppy at their next check-up.

Should I feed my puppy before or after walks?

The British Veterinary Association advises waiting at least one hour after feeding before exercising your puppy, and waiting at least one hour after exercise before feeding. This is particularly important for large and deep-chested breeds, as exercising too soon after eating can increase the risk of a life-threatening condition called gastric dilatation-volvulus (GDV), or bloat. For young puppies under 12 weeks who haven’t yet been fully vaccinated, exercise should be limited to garden play anyway.

Can I mix wet and dry puppy food?

Yes, you can absolutely mix wet and dry puppy food. Many owners find this combination works well — the dry kibble provides dental benefits and convenience, whilst the wet food adds palatability and hydration. However, be careful to calculate the combined calorie content so you don’t accidentally overfeed. A good rule of thumb is to replace roughly 25% of the dry food volume with wet food and adjust from there based on your puppy’s condition. Check out our best wet puppy food guide for quality options.

How much water should my puppy drink?

As a general guideline, puppies need approximately 50-60ml of water per kilogram of body weight per day. So a 5kg puppy would need roughly 250-300ml daily. They’ll need more in hot weather, after exercise, or if they’re eating dry kibble (which has a moisture content of around 10%) compared to wet food (which is around 70-80% water). Always ensure your puppy has access to clean, fresh water and monitor their drinking habits — excessive thirst can be a sign of illness.

When should I transition to adult dog food?

The timing depends on your puppy’s breed size. Small breeds typically transition at around 8-12 months. Medium breeds transition at around 12 months. Large breeds should wait until 12-15 months, and giant breeds may need to stay on puppy food until 18-24 months. Always transition gradually over 7-10 days by gradually increasing the proportion of adult food. If you’re unsure about the right timing for your specific puppy, consult your vet.

My puppy is not eating — what should I do?

A puppy refusing to eat can be worrying, but there are several common causes. First, rule out illness — if your puppy hasn’t eaten for more than 24 hours, seems lethargic, is vomiting, or has diarrhoea, contact your vet immediately. If your puppy seems healthy but is just being fussy, try offering their food at the next scheduled meal time without offering alternatives. Remove the bowl after 15 minutes if they don’t eat. Sometimes puppies are simply not hungry, or they may be holding out for tastier treats. Ensure you’re not overfeeding treats between meals, and avoid making meal times stressful. If the problem persists beyond a couple of days, seek veterinary advice.

Should I feed my puppy treats between meals?

Treats are an important part of puppy training and bonding, but they should be given in moderation. The general guideline from veterinary professionals is that treats should make up no more than 10% of your puppy’s daily calorie intake. Choose small, low-calorie training treats and factor them into your puppy’s overall daily food allowance. Avoid human food treats, especially those that are salty, fatty, or contain toxic ingredients like chocolate, raisins, or onions. For a full list of dangerous foods, see our guide on what not to feed your puppy.

Can puppies eat the same food as adult dogs?

Puppies should not eat adult dog food as their main diet during their growth period. Puppy food is specifically formulated to meet the higher protein, fat, calorie, vitamin, and mineral requirements of growing dogs. Adult food simply doesn’t provide the right balance of nutrients for a developing puppy, which could lead to stunted growth, weakened bones, and immune system problems. Once your puppy has reached their appropriate age for transition (based on breed size), you can switch to adult food using a gradual transition method.

Final Verdict

Feeding your puppy correctly is one of the most important things you can do to ensure they grow into a healthy, happy adult dog. The key takeaways from this guide are:

  • Feed the right amount for their age and breed size — use our feeding chart as a starting point and adjust based on your puppy’s individual body condition.
  • Choose a complete, age-appropriate puppy food — preferably one that’s been formulated according to FEDIAF guidelines and suits your puppy’s breed size.
  • Follow a consistent feeding schedule — start with 4 meals per day at 8 weeks, gradually reduce to 2 meals per day by 6 months.
  • Monitor their body condition regularly — use the body condition score system to ensure your puppy is growing at a healthy rate.
  • Never free-feed — measured portions at set times lead to better eating habits, easier house training, and a healthier weight.
  • Transition to adult food at the right time — based on breed size, and always do it gradually over 7-10 days.

Remember, every puppy is an individual.
