How to Feed My Pet

The 10% treat rule isn't really about calories

Here is the mistake that quietly makes pets overweight, and almost nobody notices they are making it: feeding the recommended amount of food, and then treats on top.

The daily calorie requirement is the whole budget. Treats come out of it, not in addition to it.

Our editorial guidance
This is why the calculator shows the breakdown as a split rather than a sum — total needed, then treats, then food as the remainder. Enter 180 kcal of treats and the food figure drops by the corresponding weight. You are not being told to feed more; you are being shown how the same budget divides.

How we label our evidence

  • Evidence gapWe could not verify this in our approved sources, so we have not invented a number.

Why the ceiling is 10%

The usual explanation — "treats are fattening" — misses the actual reason, which is more interesting and more important.

A complete pet food is formulated as a balanced diet: protein, calcium, essential fatty acids, vitamins and minerals all in proportion to each other. Treats are not formulated that way. Once treats take up a large share of daily intake, they are displacing the balanced portion — and the ratios that the complete food was carefully built to deliver stop being delivered.

So an animal can be eating the right number of calories and still be getting an unbalanced diet. That is what the 10% guideline is protecting, and it is why the calculator warns about nutrient balance rather than about weight when you go over.

The small-dog problem

The smaller the animal, the harder this gets. A single dental chew might be around 75 kcal. For a 30 kg dog needing roughly 1,250 kcal a day, that is about 6% — fine. For a 5 kg dog needing around 350 kcal, the same chew is over 20% of the day, and the 10% ceiling is gone before you have given anything else.

The calculator flags this for dogs under 10 kg specifically, because the arithmetic is genuinely unforgiving at that size — and because a 30% error from a measuring cup matters a great deal more when the whole day's ration is 90 g.

Treat these as placeholders. Product-to-product variation is large — the same category of dental chew can differ by a factor of two between brands. We have not verified these against a systematic source, and the figure printed on your own packaging beats every number in this table.

Practical ways to stay under

  • Break them up. Most dogs respond to the event of getting a treat, not its size. A chew snapped into four pieces is four rewards.
  • Use the daily ration. Setting aside part of the measured food for training moves calories from one pocket to the other instead of adding them.
  • Count what everyone gives. Households routinely double-feed treats without realising, because each person only counts their own.

The treats field is in the "Treats" tab of the dog and cat calculators — either as a total, or itemised if you are not sure. On a diet, read safe weight loss alongside it.
