Feeding Your Puppy: Nutrition for the First Year
What you feed your puppy in the first year shapes their growth, their energy and their long-term health. From sticking with the breeder's food in the early weeks to choosing a growth formula and managing treats, this guide covers the practical decisions every new owner faces at the food bowl.

Start with What the Breeder Was Feeding
Bringing a puppy home is a big upheaval for a small dog: new people, new smells, new routines. Changing their diet on top of all that is a reliable recipe for an upset tummy. A good breeder will tell you exactly what the puppy has been eating and will often send you home with a few days' supply. Keep feeding that same food for at least the first week or two.
When you do want to switch foods, do it gradually over seven to ten days. Start by mixing a small amount of the new food into the old, then slowly shift the ratio each day until the new food has fully taken over. If your puppy develops loose stools or goes off their food during the transition, slow down and give their digestion time to catch up. If you're still choosing a breeder, this handover of feeding information is one of the small signs of a careful operation, and our guide to selecting the right breeder covers what else to look for.
Puppy Food Is Not Just Marketing
Growth formulas exist for a genuine reason. Puppies need more energy, protein, calcium and certain fatty acids per kilogram of body weight than adult dogs, and in carefully balanced proportions. A quality complete puppy food is formulated to deliver that balance; adult food is not. Look for a food labelled as complete and balanced for growth.
This matters most for large and giant breeds. Puppies that will mature over about 25 kilograms grow for longer and are prone to joint and skeletal problems if they grow too fast or get the calcium balance wrong. For these dogs, choose a food specifically formulated for large breed puppies and keep them lean rather than roly-poly. If you're not sure how big your puppy will end up, our breed profiles list typical adult sizes for the breeds common in Australia.

How Often to Feed
Small stomachs need small, frequent meals. As a general guide:
- 8 to 12 weeks: four meals a day, evenly spaced
- 3 to 6 months: three meals a day
- 6 to 12 months: two meals a day, which most dogs stay on for life
Feed measured amounts at set times rather than leaving food out all day. It makes toilet training more predictable, helps you notice quickly if appetite drops, and keeps portion sizes honest. The feeding guide on the packet is a starting point, not a rule: adjust based on your individual puppy's condition.
Treats Count Too
Treats are essential for training, but they are not a bonus on top of the daily food allowance, they are part of it. A common rule of thumb is that treats should make up no more than about ten percent of your puppy's daily intake. Use tiny training treats, break bigger ones into pieces, and consider setting aside part of the day's kibble to use as rewards. A puppy will work just as hard for a piece of their own dinner as for anything fancy.

Foods That Are Dangerous for Dogs
Some everyday human foods are toxic to dogs, and puppies are especially vulnerable because of their small size. Keep these well out of reach and make sure everyone in the household knows the list:
- Chocolate: the darker the chocolate, the more dangerous it is
- Grapes, raisins and sultanas: even small amounts can cause kidney damage
- Onion, garlic, leek and chives: raw, cooked or powdered
- Xylitol: an artificial sweetener found in some chewing gums, lollies and peanut butters
- Cooked bones: they splinter and can pierce or block the gut
- Alcohol, caffeine and macadamia nuts
If you suspect your puppy has eaten any of these, contact your vet or an emergency animal hospital straight away rather than waiting to see if symptoms appear.
Water, Body Condition and Your Vet
Fresh, clean water should be available at all times, refreshed daily and checked more often in hot weather. It is easy to overlook, but it is the most important nutrient of all.
Keep an eye on body condition rather than just the number on the scales. On a healthy puppy you should be able to feel the ribs easily without them being visibly prominent, and see a waist when looking from above. Puppy fat is not harmless: overweight puppies are more likely to become overweight adults with joint problems.

Finally, treat your vet as a partner in your puppy's nutrition. Vaccination and check-up visits during the first year are the perfect opportunity to have your puppy weighed, discuss body condition, and plan the switch from puppy food to adult food, which happens at different ages depending on breed size. Good food, sensible portions and regular vet input will set your dog up for a long, healthy life together.
