Free Puppy & Litter Weight Tracker
Built for breeders: log every puppy in the litter, compare them on one chart, spot the one falling behind, and print clean records for your vet or new owners. Free, no account — everything stays on your device. Works for any animal you weigh, not just puppies.
How it works
- Create a litter — give it a name (e.g. "Frenchie April Litter")
- Add each puppy by name or collar colour
- Log weights as often as you want — recommended 2–3× per day for newborns
- Read the chart — use % change mode to compare puppies of different sizes fairly
- Print records using the print button — clean handout for your vet or new owners
