Explanation

Growing puppies generally need more energy relative to body size than adult dogs. Their needs change during growth, so a calculated value should be reviewed against growth rate, body condition, the food label, and veterinary advice.

Formula and methodology

After converting weight to kilograms, RER = 70 × weight in kg^0.75. The estimate uses 3 × RER for puppies under four months and 2 × RER for puppies four months or older that are still growing.

Worked example

A 5 kg puppy has an RER of about 234 kcal/day. If under four months, the 3.0 growth factor gives about 702 kcal/day. If older and still growing, 2.0 × RER gives about 468 kcal/day.

Assumptions and limitations

This is for healthy growing puppies only. Growth rate, expected adult size, activity, body condition, environment, neuter status, and food characteristics can affect intake. It does not replace veterinarian or pet-food feeding guidance.## Methodology references

Frequently asked questions

When should I switch age groups?

Use the older group from four months while the puppy is still growing.

Does expected adult size matter?

It can affect growth planning, which is why regular veterinary monitoring remains important.

Is this a guaranteed feeding amount?

No. It is an energy estimate that must be compared with food guidance and the puppy’s response.
