Catch the puppy that stops gaining.
Weigh-ins in whatever unit you used, charted on one axis, so a fading puppy shows up as a flat line instead of a feeling.

Grams at birth, pounds at eight weeks
A litter is routinely weighed in grams on day one and pounds by the time it leaves. Every reading is converted to a common scale, so the chart is continuous even though your notes never were.
A litter on one chart
Puppies side by side, not one at a time. The one falling behind its siblings is the point of weighing them at all, and it is visible at a glance rather than by comparison in your head.
Parents too, not just puppies
Sires and dams carry their own weight history — useful for condition before a breeding, and it is what the genetics forecast uses to estimate an adult size range.
Weigh, log, and see it.
The scale is already in the whelping room. This is what happens to the number afterwards.

Weigh the litter
In whatever unit your scale is in. No converting in your head at 2am.
- 02
Log it from the phone
Beside the whelping box, which is the only place a weigh-in gets recorded reliably.
- 03
Watch the curve, not the number
Growth per puppy, across the litter, on one chart.
- 04
Act on the flat line
A puppy that stops gaining is the earliest warning you get, and the whole reason the log exists.
Common questions
Do I have to convert grams to pounds?
No. Log whatever your scale says — grams at birth, ounces at a week, pounds at eight — and KennelBoss puts them on one scale so the chart runs continuously.
Can I see the whole litter at once?
Yes, side by side. Finding the puppy falling behind its siblings is the reason to weigh them, and it does not work one puppy at a time.
Can I weigh adults too?
Yes. Sires and dams keep their own weight history — useful for condition before a breeding, and it is what the genetics forecast uses to estimate an adult size range for a pairing.
What am I actually looking for?
A flat line. A puppy that stops gaining is the earliest warning you get, and it shows up on the chart days before it is obvious in the box.
Know which puppy is struggling, on the day.
Every weigh-in, every unit, one growth chart per litter.
