One litter, from breeding date to go-home day.
Set the breeding and KennelBoss works out the rest of the calendar — then carries the litter through whelping, weeks of growth, and the day the puppies go home.

The dates work themselves out
Give it the breeding and the rest follows: when to scan, when she is due, and when the puppies are eight weeks old and ready to leave. A go-home date you set yourself overrides it — but you should not have to count weeks on a calendar to get one.
Awaiting birth and born are different litters
A litter you are waiting on and a litter you are raising need different things from you, and they read differently in the list. Marking a litter born is the moment the whole record changes shape.
The litter is the thing everything hangs off
Puppies, weights, vaccine schedules, expenses and buyers all attach to it. That is why the cost of a litter and the profit from it are figures rather than an afternoon with a calculator.
Breeding date in, whole litter out.
The calendar a breeder keeps in their head, worked out once and kept in one place.
- 01
Create the litter from the breeding
Dam, sire, breeding type and date — the pairing you already planned.
- 02
Let it fill in the calendar
Ultrasound, due date, and the eight-week go-home day, ready to adjust.
- 03
Mark it born and add the puppies
The litter changes from expected to real, and everything below it wakes up.
- 04
Raise it in one place
Weights, vaccines, photos and costs, all against this litter.
- 05
Send them home
Go-home day is a date the record has known about since the breeding.
Common questions
Do I have to work out the due date myself?
No. Give it the breeding and KennelBoss fills in the calendar — when to scan, when she is due, and the eight-week go-home day. Set your own go-home date any time you want a different one.
What changes when I mark a litter born?
Everything below it wakes up. The litter stops being one you are waiting on and becomes one you are raising: puppies, weights, vaccine schedules and costs all attach from that point.
Is this the same thing as publishing the litter?
No. This is the litter as you run it. Publishing it to buyers is a separate step, so a litter can be fully managed here and visible to nobody until you decide otherwise.
Can I still change dates after the fact?
Yes. The calculated dates are a starting point, not a commitment — a bitch who whelps early does not need you to fight the software about it.
Stop counting weeks on a wall calendar.
Every litter, its dates, its puppies and its costs — in one record.
