Feeding Guide

These amounts are a starting point only because animals' needs vary. Adjust the feeding amount to maintain optimal body weight.


Science PlanTMpuppy formulas should be fed from weaning until maturity at 1 year old. The daily amount required by individual puppies typically varies by ±16% (e.g. a 4 month old, 4kg puppy may require between 105 and 145 grams of these Science PlanTMPuppy Healthy DevelopmentTMdry formulas per day). Therefore these amounts should be adjusted to maintain optimal body weight, and fed as 2-4 meals per day (the number may decrease with age). A 370g can is equal to 125 grams of the dry food.

Additional information

  • During the last half of lactation, puppies can be weaned on to the same Science Plan™ Puppy food that is being fed to the bitch, which simplifies the weaning process.
  • Science Plan™ Puppy Healthy Development™ formulas are enriched with a high level of DHA (docosahexaenoic acid), an essential structural component of the brain which occurs naturally in mothers' milk. All Science Plan™ Puppy Healthy Development™ formulas (other than Large Breed) can be fed to pregnant and lactating bitches and will provide puppies with a high level of DHA before weaning. When the appropriate Science Plan™ Puppy formula is also fed to puppies after weaning, additional DHA is supplied throughout the critical formation and development of brain and eyes.

Recommended for

  • Puppies of small and medium breeds from weaning
    until 1 year old
