How much should I feed if my dog's weight is exactly between two amounts on the feeding chart?

Most feeding charts list amounts for specific weight brackets, such as every 2 or 5kg, to keep the chart a manageable size, which means any dog whose weight falls between two printed rows is left to interpolate somehow.

Simply rounding to the nearest row, or averaging the two nearest figures, works reasonably well as a rough guide but is less accurate than calculating directly for the exact weight.

Use your dog's exact weight in the resting energy formula, 70 times weight in kilograms to the power of 0.75, then apply your chosen activity multiplier, which gives a number specific to your dog rather than an estimate based on the nearest chart bracket.

This calculated figure will almost always land sensibly between the two chart rows your dog's weight falls between, confirming that the chart's bracketing was a reasonable simplification rather than something wildly different from the precise calculation.

Once you have your dog's exact weight, recalculating precisely takes only a minute using a calculator or a food calculator tool, so there is little reason to rely on chart interpolation guesswork at all.

Recalculate whenever your dog's weight changes meaningfully, rather than continuing to use a chart bracket that was accurate at a previous weight but may no longer be the closest match.
