Two practices each holding half a vaccine history is a filing problem, not a lost cause: neither clinic can see the other's entries, so the full picture exists only once somebody deliberately assembles it. Your job is to collect both halves, have them merged into one file at the clinic you use now, and keep a personal copy that no longer depends on either practice's cabinet.
Collect a Complete Copy From Each Clinic
Contact both clinics and ask each for everything it holds on your dog, not just the most recent booster. A useful copy shows the vaccine name or product, the date it was given, and the date the next dose falls due, printed or stamped by the practice itself. Ask specifically whether either clinic gave rabies vaccinations, because that entry is the one boarding facilities, groomers, and travel checks ask about first. If a clinic has closed or changed hands, ask where its records were transferred; practices normally pass files to a successor or a storage service rather than destroying them.
Ask Your Current Clinic to Merge the File
Take both copies to the clinic you will actually use going forward and ask the team to file them together as one record. Where the two halves overlap, the dates should match; where they leave a gap, ask the clinic to note the gap as unknown rather than filling it in from memory or guesswork. A booster given on an assumed date can leave your dog under- or over-vaccinated, and an honest gap lets the vet decide whether a dose needs repeating. Leave the visit with the merged record copied for you as well, so the combined version exists in your hands and not only on the clinic's system.
Keep Your Own Master Copy at Home
From now on, treat yourself as the record's permanent home and the clinics as contributors. After every appointment, add the new entry to your copy the same day: what was given, by which clinic, and when it expires. Photographing each new certificate as a backup protects you if paper is lost, and a lost card stays a minor inconvenience because the issuing clinics can rebuild their parts from their own systems. Note the microchip number alongside the vaccine pages, since facilities often check identity and vaccination together.
Why the Merged Record Matters on Busy Days
The split record causes trouble at exactly the moments nobody has time to chase paperwork: a boarding kennel refusing check-in, a new vet unable to tell whether a booster is due, or a sitter who needs medication details alongside vaccination proof. One merged file answers all of those in a single hand-over. With the two halves finally together, KinsLe's Pet Passport holds them in one place, so your dog's combined history can be produced at appointments, on the road, and whenever care passes to someone else.
