What is PupSaga?
Key Features
Four connected calculators. Dog Age, Puppy Growth, Dog Weight, Dog Pregnancy — each one links to the other three, and they share dog profiles and kg/lb conversion.
Age by size, not by "times seven". Pick the expected adult size (Small ≤20 lb / 9 kg, Medium 21–50 lb, Large 51–100 lb, Giant >100 lb), get a calendar age, a life stage, and a 1–16 dog-to-human chart.
A weight log, not a verdict. Add dated measurements with a unit, get a chart with a zero baseline and dates spaced by real elapsed time, then export CSV or print the record for a vet visit.
Pregnancy dates with a documented method. First breeding date +63 days as a working estimate, with the +58 to +72 reference window; a vet-confirmed ovulation date switches to a separate +63-day anchor and a narrower +62 to +64 window.
Local-only data with real backups. Records stay in this browser; CSV for reading and sharing, JSON backup in My Dog for restoring after a device or browser change.
Use Cases
- Keep dated puppy weight measurements separate from illustrative growth predictions.
- Build a weight history to export as CSV or print for a veterinary appointment.
- Explore a size-aware human-age comparison using expected adult size.
- Organize a pregnancy due-date estimate and reference window from a breeding or vet-confirmed ovulation date.
How to Use PupSaga
- 1Open the tool you need. Start from Dog Age, Puppy Growth, Dog Weight or Dog Pregnancy — no signup screen in between.
- 2Enter the minimum the tool needs. Age or birthday plus expected adult size; or current weight, age in weeks and adult size; or a date and a weight; or the first breeding date.
- 3Read the result and its caveats. Each tool shows the estimate next to a Calculation method and a "what this page will not tell you" section.
- 4Save it to a local dog profile. Add a dog name in My Dog, save the result, and export CSV or JSON when you want a copy outside the browser.

FAQ
Is PupSaga free?
Yes. The four public tools are free and do not require an account. No paid tier or trial limit was shown on the reviewed pages.
Does it store my dog’s data on a server?
The privacy policy says dog profiles, measurements, inputs and saved results remain in this browser and are not sent to a PupSaga database or external AI service. There is no account or automatic sync. Export CSV for reading/sharing and a My Dog JSON backup for restoration before clearing site data or changing devices. Hosting request data and website analytics are handled separately.
Can the weight calculator tell me my dog’s ideal weight?
No. It records dated measurements and draws a chart. It does not calculate ideal weight, score body condition, diagnose a change, or recommend a feeding adjustment. Consult your veterinarian about changes that concern you.
How does the dog age calculator work?
It uses a birthday or known age together with expected adult size to show an illustrative human-age comparison for ages 1–16. The medium-size reference follows an AVMA educational poster; other size adjustments are PupSaga simplifications. It is not a biological-age or health assessment.
How accurate is the pregnancy due-date estimate?
The tool uses first breeding date +63 days as a working estimate, with a +58 to +72 day reference window. With a vet-confirmed ovulation date, it uses that separate anchor +63 days and a +62 to +64 day window. The ranges are not combined. These are estimates, not pregnancy confirmation, delivery-risk assessment, or a guarantee of a due date.
