How to choose the best puppy food in South Africa
Quick answer: The best puppy food is a complete and balanced food made for growth that matches the size your puppy will be as an adult. If your puppy will be a big dog, choose a food that states it is suitable for large-breed growth. Then feed measured meals, keep an eye on body condition, and move to adult food once your puppy is fully grown.
Walk down any pet food aisle and you’ll see dozens of puppy bags, all promising the world. The good news is that you don’t need to decode every ingredient. A few checks on the label, plus some sensible feeding habits, will get you to the best puppy food for your dog.
Why puppies need a growth food
Puppies are building bone, muscle and organs, so their nutrient needs differ from an adult dog’s. A food made for adult maintenance isn’t designed to cover those needs.
That’s why the most important words on a puppy food are the ones that say who the food is made for. Look for a food labelled complete (not “complementary”) and suitable for growth or all life stages.
What to look for on the bag
1. A “complete” food for growth
The World Small Animal Veterinary Association (WSAVA) suggests checking that a food is labelled complete and that it suits your pet’s life stage. A good label will also say how adequacy was established: by formulation to a recognised nutrient profile (such as AAFCO or FEDIAF), or by feeding trials.
Foods sold for short-term, intermittent or complementary feeding, such as treats and toppers, should make up no more than about 10% of the diet.
2. The large-breed statement
This is the one many owners miss. Large and giant breed puppies are more sensitive to calcium levels while their bones grow, and too much calcium is a known risk factor for developmental bone and joint problems.
In the US, AAFCO now requires growth foods to say whether they are suitable for large-size dogs, defined as 70 lb (about 32 kg) or more as an adult. Read this carefully. “Including growth of large-size dogs” and “except for growth of large-size dogs” look almost the same but mean the opposite. If the label doesn’t say, ask the manufacturer or choose a dedicated large-breed puppy food.
Adding a calcium supplement to a balanced puppy food is not a good idea. More calcium does not mean stronger bones.
3. Calories and the feeding guide
The feeding guide on the bag is a starting point based on an average puppy. Your puppy’s activity, breed and body condition will decide the real amount. WSAVA notes that calorie content isn’t required on every label outside the US, so if it’s missing, the manufacturer should be able to tell you.
Questions worth asking the pet food company
WSAVA’s guidance on selecting a pet food suggests a few questions you can put to any brand. A reputable company should answer them easily:
- Do you employ a qualified pet nutritionist (for example, a PhD in animal nutrition or a board-certified veterinary nutritionist)?
- Who formulates your foods?
- What quality control do you use, from ingredients to the finished product?
- Do you do or fund nutrition research, and is it published?
- Is the food made by you, or by a third party for you?
WSAVA also warns that terms like “holistic” and “premium” aren’t regulated, so don’t choose on marketing words alone. An ingredient list on its own also won’t tell you much about overall quality.
Match the food to your puppy’s adult size
Dogs of different sizes grow at very different rates. Royal Canin’s guidance gives a useful rule of thumb for when puppies reach adulthood:
- Small and toy breeds: around 9 to 10 months.
- Medium breeds: around 12 months.
- Large and giant breeds: between 15 months and 2 years.
Small and toy breed puppies
Small puppies have small mouths and stomachs, so a small kibble made for small-breed growth is usually easier to eat. Browse our small breed dog food for small-breed puppy formulas.

Medium breed puppies
A standard puppy food labelled for growth or all life stages is the usual choice for medium breeds.

Large and giant breed puppies
Big puppies should grow steadily, not as fast as possible. The American Kennel Club notes that overfeeding drives excessive growth, which is linked to developmental orthopaedic disease, and advises against free feeding. Pick a large-breed puppy formula and see our large breed dog food page for options.

How much and how often to feed
- Start with the feeding guide on the bag for your puppy’s age and expected adult weight.
- Weigh or measure every meal. Eyeballing almost always leads to overfeeding.
- Feed several smaller meals a day instead of leaving food out all day.
- Check body condition every week or two. You should be able to feel the ribs easily under a thin layer of fat, and see a waist from above.
- Adjust the amount based on body condition, not just what’s left in the bowl.
Count treats and training rewards as part of the daily food, and keep them small.
When to switch to adult food
Switch when your puppy is close to adult size, using the ages above as a guide. Your vet can confirm the timing, especially for mixed breeds.
Change food gradually over about a week. Royal Canin suggests roughly 75% old food for the first two days, 50/50 for the next two, then 25% old food, then fully on the new food. If your puppy’s tummy gets upset, slow down.
Your puppy food checklist
- The label says “complete” and suitable for growth or all life stages.
- If your dog will weigh about 23 kg or more as an adult, the food says it is suitable for large-breed growth (AAFCO’s cut-off is about 32 kg, but some experts prefer the lower figure).
- The company can tell you who formulates its food and how it checks quality.
- You know how many calories are in a cup or 100 g.
- You weigh meals and adjust based on body condition.
- No calcium or other supplements unless your vet recommends them.
- You have a plan to switch to adult food at the right age.

Frequently asked questions
There’s no single best food for every puppy. The best choice is a complete food made for growth (or all life stages) that suits your puppy’s adult size, from a company that can explain who formulates it and how it checks quality. Large-breed puppies need a food that states it is suitable for large-breed growth.
As a guide, small breeds are adult at around 9 to 10 months, medium breeds at around 12 months, and large and giant breeds between 15 months and 2 years. Switch gradually over about a week, and ask your vet if you’re unsure.
Only if the label says it is suitable for the growth of large-size dogs. Large-breed puppies are more sensitive to calcium levels, so a food made for large-breed growth is the safer choice.
