How much to feed
How much should I feed a 25kg dog?
Last updated 23 September 2026 · How we write and check this
Short answer
A 25kg dog typically needs about 315 to 335g of a standard dry food a day. This weight sits right at the boundary between medium and large breeds, and dogs here often gain weight gradually over months rather than suddenly, so a slow, steady creep upward is the pattern to watch for rather than a sharp change.
The daily amount
Resting energy for a 25kg dog is around 783 kcal, and a typical neutered adult at normal activity needs close to 1.6 times that, about 1,250 kcal a day. At 350 to 400 kcal per 100g of dry food, that lands near 315 to 335g.
This is the amount for a dog getting regular daily walks, not one that is mostly sedentary or one that is unusually active.
Why gradual weight creep is common here
Larger breeds at this weight often show weight gain slowly, sometimes half a kilogram every couple of months, which is easy to miss without regular checks since the change on any single day is invisible.
By the time a rounded belly or a lost waistline is obvious, a dog can already be carrying several kilograms more than ideal, which is harder to correct than catching a small gain early.
Catching the drift early
Weigh your dog monthly and keep a simple record, since comparing against a number from six months ago is far more useful than judging by eye alone.
If the trend is upward for two months in a row with no change in activity, reduce the daily total by about 10 percent rather than waiting to see if it corrects itself. Photographing your dog from above and the side on the same day each month, in similar lighting, makes small shifts in shape far easier to compare over time.
Key takeaways
- A 25kg adult dog typically needs about 315 to 335g of dry food a day.
- Weight gain at this size tends to be gradual and easy to miss without regular checks.
- Monthly weigh ins with a written record catch trends that daily glances miss.
- Act on a two month upward trend rather than waiting for an obvious change in shape.
