The file is part of the dog you hand over
A rehomed dog arrives in a new home carrying a history only paperwork can tell. The new owner cannot ask the dog when the last booster was given, which food upsets her stomach, or why she flinches at a raised broom — but a complete file answers all of it on day one. Treat the document handover as part of the rehoming itself, not an afterthought once the lead has changed hands. A dog whose records travel with her settles faster, gets safer vet care sooner, and keeps the continuity that a change of home already disrupts enough.
Health and identity documents first
Start with the papers another professional will ask for. The vaccination record and rabies certificate show what cover the dog carries and when it lapses. Vet history — consultation notes, test results, operations, dental work, known conditions and reactions — should go across whole, including the unflattering pages about weight gain or a bite incident, because the new vet needs facts, not a sales summary. Microchip paperwork is the most time-sensitive piece: hand over the chip number and registry details and agree who contacts the registry, and when, so the registered keeper changes promptly. A dog found wandering in her first unsettled week must ring the new owner's phone, not the old one.
Ownership, agreements, and insurance
Include the paper trail of how the dog came to you: the original adoption agreement, purchase paperwork, or a previous rehoming note, so her chain of ownership reads clearly. If an insurance policy is running and can continue or be transferred under its terms, pass the policy details and claims history; if it ends with you, say so plainly so the new owner arranges cover without a gap. Then both parties should sign a simple transfer note recording the dog's name, description, and microchip number, the names of both parties, and that ownership is passing over. Keep a copy each. That single page prevents nearly every later dispute about whether the dog was lent, fostered, or given.
The care knowledge that lives outside the vet file
Vet records say what was done; the new owner also needs what daily life has taught you. Write a routine sheet covering food and amounts, walk habits, house-training status, cues she knows, fears and triggers, how she travels, and how she behaves with children, cats, and other dogs as you have actually seen it. Be honest about the hard parts — separation anxiety, guarding, a shaky recall — because a prepared owner copes, while a surprised one may give up. Add the practical extras: which vet and groomer she knows, any training classes attended, and the blanket or toy that smells of your home and should travel with her.
Do the handover in one bundle, and keep a copy
Assemble everything before the day, paper in one folder and digital copies sent the same day, and walk through it together rather than posting it after. Keep a copy of the transfer note and the microchip confirmation for your own records even after she leaves; questions can surface months later, and a retained copy answers them kindly and quickly. Then check in once, a little later, that the registry update actually completed — the most important page in the bundle is the one whose change someone must confirm, not just intend.
That complete handover is built into KinsLe through Transferrable Profiles, which pass a dog's profile to her new owner with her history, records, and routines intact from the first day.
