Puppy growth by breed
Every breed here has a published adult weight we can cite. Each page pairs that standard with the growth curve for its size category, so you get a weight table anchored to your actual breed instead of a generic one. Breeds without published figures are not listed, and we say which and why.

Doodles and other Poodle crosses
These crosses have no single published adult standard. Their pages compare the two parent standards for each Poodle variety, then use the puppy’s own weight and age for the estimate. A parent-standard span is context, never a promised outcome.
How to read these pages
The five size categories come from Salt et al. 2017, who grouped dogs by adult bodyweight rather than by breed, because that is what predicts a growth curve. A breed lands in a category on its average adult weight across both sexes, which is how the original research assigned them, so a breed whose males and females differ widely still gets one category.
That grouping has a visible edge case worth knowing about. The Labrador Retriever averages 30.6 kg and the Golden Retriever 29.5 kg, so two very similar dogs sit either side of the 30 kg boundary and draw different curves. Neither is wrong; the boundary is just a line drawn through a continuum, and it is a reminder that a category is a bucket rather than a measurement of your dog.
The full argument, including how far each breed sits from its category median and what that means for the numbers, is in are breed growth charts really breed specific?
Questions about breed charts
Are these growth charts breed-specific?
Partly, and the honest answer matters here. The shape of each curve comes from the five adult-weight size categories in Salt et al. 2017, because that is how the underlying data is organised. There is no breed dimension in it.
The scale is breed-specific: each table is anchored to that breed's own published adult weight from an official standard. So two breeds in the same category share a percentage-of-adult curve but get different weight tables, which is the most a page can honestly claim from this data.
Why is my breed not listed?
Because we could not find a published adult weight from an official standard that we would be willing to cite. We check beyond the AKC where another recognised standard exists: that is how the FCI's metric Cane Corso range qualified.
We would rather have 40 pages built on real figures than two hundred built on estimates.
Which breeds does the growth reference not cover?
Any breed averaging more than 40 kg as an adult, which is where the source data stops. That is 7 of the breeds here, including the Bernese Mountain Dog, Cane Corso, Great Dane and others.
Those pages still work, because the percentage curve for the heaviest category is the closest thing available, but each one says plainly that it is being applied past the edge of the data rather than pretending the data goes further than it does.
My puppy is a mix. Which page should I use?
Use the mixed breed calculator, which works from your puppy's current weight and age rather than applying either parent's purebred standard as though it belonged to the cross.
If you have a Goldendoodle, Labradoodle or Cockapoo, the crossbreed pages below show how much the relevant parent standards change with the Poodle variety. Those spans are context, not guaranteed limits for an individual puppy.
