Puppies grow quickly, and what they eat in those early months matters. The best puppy food needs to meet every need, from supporting healthy growth and brain development to digestion and immune health, all while giving your puppy enough energy for all that playing, learning and growing.
Here’s a guide to what to feed a puppy, covering the nutrients they need, and how to choose the right food based on breed.
Why Choosing the Right Puppy Food Matters
Puppies do a lot of growing in a short amount of time, so their food needs to work harder than adult dog food. They need higher levels of energy, quality protein, healthy fats and key nutrients to support their changing bodies. The right formula helps build strong muscles, supports healthy bone development and provides nutrients such as DHA for brain and eye development.
That’s why puppy food should be chosen for your puppy’s stage, size and breed, rather than simply feeding a smaller portion of adult food.
What to Look for in Puppy Food
Some puppy foods do far more for your dog than others. Certain “premium” dog foods still contain high-glycaemic grains, low-quality proteins or cheap fillers that don’t actually provide your puppy any nutritional value.
Ingredients such as corn, wheat, soy, or tapioca may fill a bag, but they don’t support your puppy’s development. If you’re working out what to feed a puppy, these are the things we suggest looking out for.
Complete and Balanced Nutrition
A good puppy food should be complete and balanced for growth. That means it contains the right mix of protein, fats, vitamins and minerals, rather than relying on one impressive ingredient or marketing claim.
High-Quality Protein
Active dogs need high-protein diets because protein is one of the building blocks for muscles, tendons, ligaments, and cartilage. Animal protein is particularly good for growing dogs, because it has a strong amino acid profile.
Healthy Fats and DHA
Healthy fats give puppies concentrated energy, which they need plenty of as they grow. Omega-3 fatty acids like DHA and EPA are found in fish, and these support neurological and cognitive development, as well as eye and brain health in puppies. Including these nutrients in your puppy’s diet sets them up for success.
Vitamins and Minerals for Growth
Minerals like calcium and phosphorus are needed for healthy bone development, but too much or too little can cause skeletal issues, especially in large-breed puppies. Large breed formulas are formulated to carefully manage calcium levels in order to support longer growth periods and reduce the risk of joint and orthopaedic problems.
Biologically Appropriate Ingredients
Puppies need food that consists of ingredients their little bodies know how to use. That’s why the best puppy food recipes focus on premium animal ingredients that align with a dog's natural diet, providing nourishment on a biological level. Look for puppy foods that have meat, poultry or fish at the top of their ingredient list, rather than grains or unnecessary fillers.
The Best Diet for Puppies Based on Stage and Size
It may sound obvious, but a Bichon and a Great Dane puppy will have very different needs. Smaller puppies benefit from a nutrient-dense food in a puppy kibble size, while large breed puppies need carefully controlled nutrition to support their long-term growth without putting extra pressure on their developing joints.
If you have a larger puppy, our guide to large breed puppy food explains why large-breed formulas are so important.
How to Transition Your Puppy to a New Food
Little tummies can become easily upset with dramatic changes in diet, so we recommend introducing any new puppy food gradually over 7–10 days.
Days 1-2: Mix 25% new food with 75% old food.
Days 3-4: Mix 50% new food with 50% old food.
Days 5-6: Mix 75% new food with 25% old food.
Day 7: Transition completely to the new food.
Always read the feeding guide on the bag, then adjust based on your puppy’s age, activity level and body condition. Monitor your puppy’s digestion, appetite and energy as they adjust. If you’re unsure when to move to adult food, we cover that in more detail in When to Switch from Puppy to Adult Dog Food.
