The free template: seven tabs, zero signup
Built the way clinics think: Pet Info (identity, microchip, allergies, clinic contacts), Vaccinations (with a certificate-location column — the field everyone forgets), Medications, Health Log (dated observations with a better/worse dropdown), Weight, Vet Visits, and Expenses. Opens in Excel, Google Sheets, and Numbers. One workbook per pet.

Where the spreadsheet genuinely wins
- It costs nothing and expires never. No subscription, no company that can shut down, no export anxiety. A spreadsheet from 2015 still opens today; not every app from 2015 does.
- Total control. Your columns, your categories, your quirks. No product manager decides what a "record" is allowed to be.
- Privacy by construction. The data sits in your account or on your disk, full stop.
- Zero learning curve for anyone who already spreadsheets. The best system is the one that gets used, and familiarity is adherence.
The three places it quietly fails
1. Rows don't ring. A next-due date in a cell is a fact, not an alarm. The spreadsheet knows the rabies booster is due in March; nothing happens in March. The calendar-event workaround genuinely works — but it doubles the bookkeeping, and doubled bookkeeping is where systems die.
2. Documents can't live in cells. The certificate, the lab PDF, the discharge note — the things clinics and boarders actually ask for — live somewhere else, and the spreadsheet can only point at them. When the pointer says "Google Drive, probably," the system has failed at the exact moment it was built for.
3. Discipline decays. Every row is typed by a human who is tired, busy, or holding a leash. Spreadsheet pet records are usually immaculate for six weeks and archaeological after six months. This is not a character flaw; it is what manual systems do — the same reason the manual-entry apps we compared share the problem.
Spreadsheet, paper, or Pawmi — honestly
| Spreadsheet | Printable PDFs | Pawmi | |
|---|---|---|---|
| Cost | Free | Free | Free tier; Pro $3.99/mo or $30/yr |
| Reminders fire themselves | No (calendar workaround) | No | Yes — created from records |
| Stores the actual documents | No, only pointers | The paper is the document | Yes — parsed and filed per pet |
| Data entry | All manual | All manual | Upload the paperwork; AI extracts it |
| With you at the emergency vet | If synced and you find the tab | Only if you brought it | Phone or any browser |
| Survives the company | Yes, indefinitely | Yes | As long as we do — keep originals regardless |
The hybrid most households should actually run
Keep original certificates in a folder. Keep either the spreadsheet or Pawmi as the system of record — not both, duplicated systems drift apart. If you run the spreadsheet: add the calendar event for every due date the moment you type it, and scan documents to one cloud folder the spreadsheet points to. If you run Pawmi: upload the paperwork and let the records, reminders, and documents stay one object. Either way, the organizing principles are the same — one pet per container, dates on everything, proof findable in under a minute.
