Pet Adoption Paperwork Checklist: Records to Keep
Use this pet adoption paperwork checklist to organize the contract, identification, vaccination history, medical records, and ownership details you receive.
TL;DR
What records should I keep after adopting a pet?
Save the adoption or transfer agreement, vaccination and deworming history, medical records, microchip details, sterilization status, medication information, diet notes, and any behavior or care instructions. Mark unknown information clearly and ask a veterinarian what should happen next.
Adoption day often comes with a folder, an email, or a few pieces of paper. Save all of it. Even an incomplete record helps the next veterinarian understand what is known, what is uncertain, and which questions need follow-up.
Pet adoption paperwork checklist
Ownership and transfer
- Adoption, purchase, foster-to-adopt, or transfer agreement
- Receipt or proof of adoption if supplied
- Shelter, rescue, breeder, or previous owner's contact details
- Date the pet came into your care
- Any restrictions or obligations in the agreement
Read the agreement before signing and keep a copy after the transfer. Requirements can vary by organization and location.
Identification
- Microchip number and registry name
- Confirmation that the chip was scanned
- Instructions for transferring the registration
- Current tag or license details
- A recent photo and distinguishing features
The AVMA guidance on selecting and bringing home a dog recommends asking for health and vaccination history and arranging veterinary care after adoption. The same record-keeping habit is useful for any newly adopted pet.
Health and care history
- Vaccination dates and product names, if available
- Deworming and parasite-prevention history
- Spay or neuter record
- Medical conditions, surgeries, allergies, and test results
- Current and recently stopped medications
- Food, feeding amount, and known sensitivities
- Dental, grooming, or mobility notes
- Behavior notes and triggers that help keep the transition calm
Do not fill gaps with guesses. Write "unknown" and bring the question to the first veterinary visit. Your newly adopted pet vet visit checklist explains how to prepare when records are incomplete.
Create a simple record system
Use one folder for originals and one digital copy for quick access. Name files with the pet's name, document type, and date, such as Milo-vaccination-record-2026-08-30.pdf. Store the microchip number and clinic contact details in a place a caregiver can find.
Keep the following separate:
| Record type | What it answers |
|---|---|
| Adoption agreement | How did the transfer happen and what terms apply? |
| Medical record | What care has a clinic documented? |
| Reminder | What needs attention next? |
| Care note | What did a caregiver observe or complete? |
Petio can connect these items to the correct pet profile. It is an organizer, not the official clinic record, so retain the original documents and share updates with the veterinary team.
Review the file after the first visit
After the first veterinary appointment, add the clinic's records and label older information as historical or unverified. Record follow-up dates only from the current veterinary plan. If the pet has another caregiver, share the practical care note without exposing account credentials or unrelated personal information.
Safety note
This is general record-keeping guidance, not veterinary or legal advice. Follow the adoption organization's terms and ask a veterinarian about missing history, vaccinations, medications, nutrition, or any health concern.

Frequently asked questions
What paperwork should I get when adopting a pet?
Ask for the adoption or transfer agreement, vaccination and deworming history, medical records, microchip details, sterilization status, current medications, diet information, and any behavioral or care notes available.
What if an adopted pet has no medical records?
Keep the paperwork you do receive, write down what is unknown, and schedule a veterinary visit to establish a record and ask which preventive care is appropriate. Do not guess a vaccine history.
Should I update the pet's microchip after adoption?
Yes. Confirm the chip number and update the registry with your current contact details as soon as the transfer is complete. Ask the shelter, rescue, or veterinarian which registry process applies.
How should I store adoption records?
Keep the originals in a safe place, make a readable digital copy, and attach records to the correct pet profile. Keep an offline copy of the most important documents for emergencies or travel.
