Dog Pregnancy & Whelping Tracker
A dog's pregnancy runs about 63 days, and the days before whelping are all about watching the signs - especially that twice-daily temperature. PetHealthLog lets you log temperature, weight and notes on one timeline, so you can spot the pre-labour drop and have a clean record for your vet. Free, no account, works offline.
Start tracking - it's freeThe pre-whelp window is easy to lose track of
Canine gestation is roughly 63 days, with normal births anywhere from about day 58 to day 68 - so a due date is a window, not a fixed point. As that window approaches, the routine becomes a daily one: weight, appetite, behaviour, and from around day 56 the temperature, taken morning and evening.
The temperature is the part most worth getting right, because a clear drop - commonly below about 99°F and staying there - often means whelping will start within roughly 24 hours. But two readings a day jotted on scraps of paper are exactly the kind of record that gets lost or muddled right when it matters most.
A simple log closes the gap. PetHealthLog is free, needs no account and works offline, so each temperature and weight goes on one timeline you can read at a glance - and hand to your vet if anything looks off.
What the tracker actually does
Log the twice-daily temperature
Record morning and evening readings from around day 56, so the run of numbers is in one place and a sustained drop toward labour stands out instead of being missed.
Track weight across the pregnancy
Note weight as it climbs through gestation, so steady progress is visible and a concern is easy to flag at a check-up.
Mark the due-date window
Keep the breeding date and the roughly day 58-68 window in view, so you know when to start the close daily watch rather than guessing.
Note appetite, behaviour and nesting
Jot appetite changes, restlessness or nesting alongside the temperature, building the picture that tells you whelping is getting close.
A vet-ready PDF
Export a clean record of temperatures, weights and notes, so a call or visit to your vet starts from real data instead of memory.
What to watch as the due date nears
Late-pregnancy monitoring usually steps up around these checkpoints - this is a general guide, not a schedule for your dog. Use the free tracker to record each step and share the history at your next visit.

Frequently asked questions
- Is this dog pregnancy tracker really free?
- Yes. Logging temperature and weight, marking the due-date window, notes on appetite and behaviour, and the PDF report are all free. There is no sign-up and no account, and your records stay on your own device.
- How long is a dog pregnant for?
- Canine gestation is roughly 63 days, though births from about day 58 to day 68 are considered normal in most breeds - so it's best thought of as a window. Your veterinarian can confirm the dates for your dog; the tracker just keeps the daily record across that window.
- What does the temperature drop before whelping mean?
- A sustained drop - commonly described as below about 99°F and staying there - often means whelping will begin within roughly 24 hours, which is why many owners take the temperature morning and evening from around day 56. The exact reading and what it means for your dog are your veterinarian's call; the tracker simply makes the twice-daily record easy to keep and read.
- Does it work offline?
- Yes. PetHealthLog is a progressive web app that works offline, so you can log a temperature or weight without a connection.
- Is this a substitute for veterinary advice?
- No. PetHealthLog is a record-keeping tool, not veterinary advice. It does not diagnose anything or manage the pregnancy. A dog's pregnancy and whelping should be overseen by a licensed veterinarian, and if labour stalls, the dog strains without producing a puppy, or anything seems wrong, contact your vet right away. The tracker just records what you observed.
