Shelter-to-home transition: the records to keep on day one
The first 24 hours of a new adoption are calm in retrospect and chaotic in real time. A short record-keeping routine on day one protects the pet during the transition and sets the lifetime record up cleanly.

Quick answer: Day one: photograph adoption paperwork, save digital copies of all shelter records, write the pet’s baseline (weight, eating, drinking, behavior), update the microchip registry, schedule a new-pet vet visit. Build the pet profile from verified records and clearly labeled gaps.
Why day one matters
New adoptions arrive with paperwork that is easy to lose. Day-one organization keeps it in the right place for the next decade. Day-one observations — weight, eating, behavior — set the baseline that future visits compare against.
The new pet is also adjusting; observation matters as much as paperwork.
What to log day one
- Photograph all paperwork: adoption contract, vaccine records, spay/neuter certificate, microchip card
- Save digital copies in a folder you control
- Note current weight — even a rough estimate is a baseline
- Note current diet — brand, amount, last fed time
- Note known medications with doses
- Note any observed behavior — shy, eating well, vocalizing, sleeping a lot
- Update the microchip registry to your contact information
- Schedule the new-pet vet visit within 7 to 14 days
The 3-3-3 rule context
Many shelters share a 3-3-3 framework: 3 days of decompression, 3 weeks of finding routine, 3 months of feeling at home. Record-keeping on day one does not push the pet; it sets up the household to support the decompression.
Do not over-handle on day one. Quiet routine first; vet visit second.
Household share
- Tell every household member where pet records live
- Set feeding and walking responsibilities for the first week
- Agree on house rules — furniture, sleeping spots, bathroom routine
- Note who handles vet calls and refills
- Share the pet profile with appropriate household members
Vet visit prep
Bring everything: adoption paperwork, vaccine records, microchip card, behavior notes, current food. The vet will conduct a baseline exam, possibly run baseline labs, and confirm the schedule for any boosters.
The vet visit is also when gaps in the shelter record are filled.
How Driyu fits
A Driyu pet profile holds the day-one record — vaccinations, microchip, weight, diet, behavior notes — in one place. As the first vet visit and the decompression weeks fill in details, the same record updates without restarting. Document scans of adoption paperwork live in the Pro Cloud Vault today; the day-one summary fields live in the free pet profile.

Frequently asked questions
What if the pet refuses to eat on day one?
Common for the first 24 to 48 hours due to stress. Offer the shelter’s food at the shelter’s schedule. If refusal extends past 48 hours, call the vet.
Should I update the microchip registry immediately?
Yes. The microchip registry is what gets you called if the pet escapes during the high-risk first week. Update it on day one.
When should I introduce other pets?
Most shelter and behavior resources recommend 3 to 7 days of decompression before any introductions. Use the 3-3-3 framework as a guide.
What if the pet shows behavior the shelter did not warn me about?
Common during decompression. Some behaviors fade as the pet settles. Others persist; a credentialed positive-reinforcement trainer is the right call.
