The label on a puppy bag is written to survive a lawsuit, not to help you at six in the morning with a hungry puppy, so here is how to actually read it. Feed a puppy a food whose label says it is complete and balanced for growth or for all life stages, split into three or four meals a day until about six months and two meals after that, and portion by body condition rather than by the bag. If your puppy will weigh 70 lb or more as an adult, the label also needs to say the food is suitable for growth of large size dogs. This post covers what the label has to say, how often and how much to feed, the large breed calcium issue, when to switch to adult food, and what not to feed a growing dog.
What the label must say
Turn the bag over and find the nutritional adequacy statement, the small print that says who the food is for. AAFCO recognizes four life stages: gestation and lactation, growth, maintenance, and all life stages. Different quantities and ratios of nutrients are needed at each stage.1 A food labeled for adult maintenance is not a puppy food, no matter what the front of the bag shows. VCA's puppy feeding guidance is direct: check the label for a nutritional adequacy statement that specifies the food has been formulated to meet the requirements for growth.2
"All life stages" foods qualify, because they have to meet the growth profile, which is the more demanding one. AAFCO notes that a food labeled this way should carry separate feeding directions for gestation and lactation, growth, and maintenance.3 If it has one set of directions for every dog, be suspicious.
Two more label words matter. A product marked for intermittent or supplemental feeding only is a treat or topper, meant to be fed alongside a complete diet, never as the whole meal.3 And puppies are the worst candidates for an unbalanced diet: the WSAVA Global Nutrition Committee warns that home prepared and raw meat based diets with nutrient deficiencies or excesses are especially harmful to puppies, who can develop painful skeletal disorders and fractures.4 Our label reading guide covers the rest of the panel.
The large breed puppy rule
If your puppy's expected adult weight is 70 lb or more, look for a specific extra phrase. VCA quotes the AAFCO wording: the food provides complete and balanced nutrition for growth, "including the growth of large size dogs (70 lb or more as an adult)."5 That phrase means the calcium level has been held within a tighter range. VCA explains that calcium in growth foods for large and giant breed puppies needs to be considered more carefully because these breeds have the highest risk of growth abnormalities, and that excessive calcium can contribute to those abnormalities.2 A calcium to phosphorus ratio of about 1.1 to 1 up to 1.4 to 1 is described as safe if the puppy is not overeating.5
Two practical consequences. First, do not add calcium supplements, bone meal, or extra dairy to a large breed puppy's diet. Second, do not let a large breed puppy get fat. A lean, slow growing Lab puppy is doing it right, even if the grandparents say it looks skinny. Our large breed nutrition guide goes deeper on this.
How often to feed
VCA suggests three to four meals a day for young puppies, because it breaks the day's food into smaller volumes for a small stomach, and puppies should be fed measured amounts at regular times based on body condition and age.26 A rough schedule that works for most owners:
- 8 to 12 weeks: four meals, spaced through the day. Toy breed puppies in particular should not go long stretches without food.
- 3 to 6 months: three meals.
- 6 months on: two meals, which VCA describes as the most common recommendation for dogs generally.6
Measured meals beat free feeding. A bowl that is always full makes it impossible to notice the day a puppy stops eating, and that is often the first sign of a problem.
How much to feed
Puppies burn far more per pound than adults. The Merck Veterinary Manual gives resting energy as 70 times body weight in kilograms raised to the 0.75 power, then multiplies by 3 for a puppy under four months and 2 for a puppy over four months, compared with 1.6 for a neutered adult.7 A 5 kg (11 lb) three month old puppy works out to about 700 kcal a day, which is more than many adult dogs twice its size. Recalculate every two weeks as the weight changes, and remember the multiplier drops at four months. Our portion guide has the full method.
Then check the puppy, not the math. You should feel ribs easily under a thin layer, see a waist from above, and see a tummy tuck from the side. Round is not healthy in a puppy. AAFCO's own consumer guidance notes that the calorie dense foods designed for young animals can make a less active adult obese, which is your cue for when the puppy food has done its job.3
When to switch to adult food
Switch when growth is essentially finished, which depends on size. Small and medium breeds finish growing first, and many vets move them to adult food around the first birthday; ask yours. VCA states that large breed dogs should stay on a growth formula until around 18 months and giant breeds until 24 months.5 Switching a large breed too early does not cause harm the way excess calcium does, but it removes the guardrails while the skeleton is still building. When you do switch, do it over at least seven days by swapping a quarter of the old food for the new every couple of days, and expect a little softness in the stool along the way.
Treats and training
Puppies get a lot of treats, because puppies need a lot of training. The WSAVA treat guide says treats should always make up less than 10 percent of a dog's daily calorie intake, and that any treat should be an appropriate size and shape to reduce the risk of choking.8 Break training treats into pea sized pieces, or use pieces of the puppy's own kibble, and take the treat calories out of the meals. Our training treats guide covers options that work.
What not to feed a puppy
- Adult maintenance food as the main diet, for the label reasons above.
- Calcium supplements on top of a complete growth food, especially for large breeds.
- Raw diets without a vet's input. The CDC does not recommend feeding raw pet food to dogs and notes that freeze drying and freezing only reduce germs rather than kill them.9 A puppy's immune system is still developing, and the WSAVA warning about unbalanced diets hits puppies hardest.4 If you want to feed raw eventually, wait until the dog is grown and read our freeze dried raw guide first.
- Human food scraps. The ASPCA Animal Poison Control Center lists onion, garlic, and chives among foods that can cause gastrointestinal irritation and red blood cell damage in dogs.10 A puppy will eat anything, which is exactly the problem.
Every puppy food in the dog food collection has been checked against The Truva Standard, and only products that passed all five checks are listed. Passing the Standard tells you about the brand's honesty, not whether it fits your puppy's size; you still have to read the life stage statement. Filtering the dog food collection by the life stage statement is the quickest way to narrow the list for your puppy. You are still the one who has to check the statement, not the puppy pictured on the front of the bag.
When to call the vet
Call if your puppy skips more than one meal, has diarrhea for more than a day, or vomits repeatedly, since puppies dehydrate fast. Call if a large breed puppy is limping, walking oddly, or reluctant to play, which can signal a growth problem. Ask your vet to weigh and body condition score the puppy at every vaccine visit and tell you if the growth curve looks too steep.
