The estimate
How we estimate adult size from the first month
A puppy's size cannot be guaranteed, but it can be estimated, and we do that from the
first month of life. We look at three things: the size of the parents and of their
lines, which we have known for years; the puppy's weight and growth curve compared with
its littermates; and the experience of many litters from the same lines. What comes out
of that is a range, not a number.
We explain the estimated range and review it as the puppy develops. Growth can vary between littermates, so leave some flexibility when planning space, equipment and travel.
