How much to feed

Why does the feeding chart on the bag seem like too much food?

Last updated 23 September 2026 · How we write and check this

Short answer

Feeding charts printed on bags are often generous averages designed to cover a wide range of dogs at a given weight, including more active ones, so many dogs genuinely need less than the chart suggests, particularly less active or already slightly overweight dogs. It is common and reasonable to feed 10 to 20 percent below a chart's figure if your dog is doing well on it.

Why charts run generous

Manufacturers often calculate feeding charts to suit an active, working weight range of dogs rather than the average pet, partly because underfeeding complaints are more visible to a brand than a slow, gradual overfeeding trend.

Charts also typically group a range of weights into one row, such as 15 to 20kg, using the figure that suits the upper end of that bracket, which overstates the amount for a dog at the lower end.

Trusting your dog's actual response

If your dog is maintaining a healthy body condition eating noticeably less than the chart suggests, that is fine, since the chart is a starting estimate, not a required minimum.

Body condition, checked by feeling the ribs and waist, is a more reliable guide than any printed number for confirming whether an amount is right for your specific dog.

When to still increase toward the chart

If your dog is losing weight, seems low on energy, or you are unsure whether a lower amount is actually appropriate, check with your vet before settling well below the chart long term.

A dog that is genuinely very active, works regularly, or is not yet neutered may need an amount closer to or even above the chart figure, so this is not a rule that applies to every dog equally, and it is worth checking whether any of these factors apply before assuming the chart is simply generous.

Key takeaways

  • Feeding charts are often generous averages, and many dogs do well on somewhat less than the printed amount.
  • Charts frequently group a range of weights together, using the upper end's requirement for the whole bracket.
  • Body condition is a more reliable guide than the chart for your specific dog.
  • Check with your vet before settling well below the chart if your dog seems low on energy or is losing weight.
