Puppy feeding and growth
How much should a 14 week old puppy eat?
Last updated 23 September 2026 · How we write and check this
Short answer
Most fourteen week old puppies are on 3 meals a day, with daily amounts still rising steadily. This is often the fastest growth window for medium and large breeds, so weigh the puppy every week or two and adjust the total food amount upward in line with the food bag's chart rather than leaving portions fixed.
A period of rapid change
Between three and four months many puppies put on more weight, relative to their size, than at almost any other stage. A medium breed puppy might gain half a kilogram or more in two weeks during this window, which means food amounts that felt generous a fortnight ago can suddenly be too small.
Coat and teeth changes affect eating too
Adult teeth are actively pushing through at this age, and some puppies chew more cautiously or favor softer food for a few days around a particularly uncomfortable tooth. This is usually short lived and not a reason to change the diet itself, just something to expect.
Keeping an eye on shape, not just weight
Two puppies of the same breed and age can need noticeably different amounts depending on activity level and metabolism. Use weight gain trends alongside a visual and hands on check: a defined waist when viewed from above is a better sign of correct feeding than matching a printed number exactly.
Key takeaways
- Fourteen week old puppies are usually on 3 meals a day with rising daily totals.
- This age often brings the fastest relative growth spurt for medium and large breeds.
- Teething discomfort can briefly change how a puppy approaches food without needing a diet change.
- A visible waist and easily felt ribs are better guides than matching a chart exactly.
