A litter holds everything about one set of puppies: each puppy, their weights, the diary and their buyers. Start the litter when the puppies are arriving or have just arrived. If mum has a pregnancy recorded, Breeders Aid links the two, so the calendar swaps the estimated dates for the real birth date.
Steps
- Tap Litters, then tap New litter. (You can also tap New litter in the Litters section of mum's profile.)
- Tap Mum, then choose her from the Who is mum? list. Use the search box if she isn't shown.
-
If mum has a pregnancy on record, you'll see a question such as Is this litter from Willow's breeding? Choose the pregnancy (for example With Rocky · due 14 Oct) to link the litter to it, or choose No — a different breeding. If there's just one, it's chosen for you and dad is filled in.

New litter with the pregnancy link for mum's breeding - Tap Dad (optional) to choose dad, or leave it.
- Check Born on. It's today unless you change it.
- Check the Litter name. It's filled in from the parents (for example Willow × Rocky). You can type your own.
-
If you have one, type the Registration litter number (optional). It's used to give each puppy its registration code.

The New litter screen with Mum, Dad, Born on and Litter name - Tap Create litter.
- Bernie celebrates. Tap Whelping mode if puppies are still arriving, or Add puppies if they're all here.
Tips
- Whelping mode is built for the whelping box: big buttons and very little typing. See Record each birth in Whelping mode.
- If you get the birth date wrong, you can fix it later with Change birth date in the litter's ••• menu (top right). See Fix a mistake in a litter or puppy.
- To add puppies one at a time later, open the litter, tap the Puppies tab and tap Add puppy.
Troubleshooting
- It says "Choose the mum first". A litter needs a mum. Tap Mum and pick her before tapping Create litter.
- Mum isn't in the Who is mum? list. Type her name in the search box. The list only shows dogs recorded as female. See Add a dog to Breeders Aid.
- I can't choose a date next week for Born on. The birth date can't be more than a day ahead. Start the litter when the puppies are arriving.
- I linked the wrong pregnancy. The link is set when the litter is created. Contact us through Help & support in More if it needs changing.
- I created a litter by mistake. If it has no puppies yet, open it, tap ••• at the top right and choose Remove litter….
