Dog Vaccination Records: What to Keep and Why

Keep a signed rabies vaccination certificate for every rabies shot, plus a dated record of each core and lifestyle vaccine your dog has received, showing the product, the date given and when the next dose is due. Those papers are what boarding kennels, groomers, daycares, new veterinarians and travel officials ask for, and the metal rabies tag on the collar is usually not accepted in their place. Below is what a complete record looks like and how long to hold on to it.

Core and non-core vaccines: what your dog's record should cover

The AAHA Canine Vaccination Guidelines sort vaccines into two groups. Core vaccines are recommended for all dogs regardless of lifestyle unless there is a specific medical reason not to vaccinate. Non-core vaccines are recommended for some dogs based on lifestyle, geographic location and risk of exposure.

Group	Vaccines listed by AAHA
Core	Canine distemper virus, canine adenovirus type 2, canine parvovirus type 2, leptospirosis, rabies
Non-core	Bordetella, Lyme disease (Borrelia burgdorferi), canine influenza, Western diamondback rattlesnake toxoid

Two details matter for your records. First, the current AAHA list places leptospirosis among the core vaccines, and its guidance notes that leptospiral vaccines need annual boosters. Second, AAHA says practices in regions where a non-core disease is endemic, such as Lyme disease, may treat that vaccine as core locally. So the "right" set of entries depends on where your dog lives and what it does. Ask your veterinarian which vaccines your dog needs; this article is not veterinary advice.

Rabies certificate vs rabies tag

Rabies is the one vaccine that is usually a legal matter as well as a medical one. AAHA's rabies guidance notes that rabies vaccination of dogs is legally mandated in many jurisdictions, and that the age at first vaccination, booster timing and whether exemptions exist may all be set by local or state law. Licensed rabies vaccines for dogs come in 1-year and 3-year formulations, and AAHA recommends a booster 1 year after the first dose regardless of which formulation was used.

• The certificate is the document your veterinarian signs. It is the record that proves the vaccination.
• The tag is a small numbered tag for the collar that links back to that record. It helps identify a vaccinated dog, but on its own it is generally not treated as proof. The City of Brownsville, Texas, for example, states that the rabies certificate, not just the tag, is the required proof.

If you only have a tag, call the clinic that gave the shot and ask for a copy of the certificate.

What a complete vaccination record shows

Whether it is a clinic printout, a certificate or a vaccination booklet, a useful entry includes:

• Your dog's identity: name, breed, sex, age or date of birth, and the microchip number if there is one.
• The vaccine: what it protects against and the product name.
• Manufacturer and lot or serial number of the dose given.
• Date given.
• Expiration or next due date. For rabies, whether it was a 1-year or 3-year vaccine.
• The clinic and the veterinarian who administered or supervised it, with signature on the rabies certificate.

The microchip line is worth checking now if you might ever travel. For U.S.-vaccinated dogs returning from a high-risk country, the CDC requires the rabies paperwork to show the microchip number and that the rabies vaccine was given after the microchip was implanted. See Traveling With Your Pet’s Vaccination Records for the full travel picture.

Why boarding, groomers and daycares ask for records

Anywhere dogs share space, one sick or unvaccinated dog puts the others at risk. AAHA's leptospirosis guidance lists time in kennels or dog daycares among the risk factors for leptospirosis, and its non-core list includes Bordetella (often combined with canine parainfluenza) and canine influenza for dogs at risk of exposure. Each business sets its own list, so ask what they require before you book, and bring the paperwork rather than assuming the clinic can be reached on the day.

A practical habit: when a facility accepts your records, note which vaccines they checked and when each expires. That tells you what to renew before the next stay.

Titers: when a blood test shows up in the file

A titer is a blood test that measures antibodies to a disease. AAHA's guidance on titers explains that a titer is not necessarily an indicator of protection or susceptibility, that the guidelines do not set "protective" values, and that routine titer testing to decide whether to revaccinate is not usually advised. It describes exceptions, such as dogs with a history of adverse vaccine reactions. For rabies, AAHA states that serologic testing is not a substitute for vaccination.

If your veterinarian does run a titer, keep the lab report with the vaccine records, dated, and ask whether a facility or authority you deal with will accept it. Many will still want the vaccination itself.

Puppies: the records that start it all

A puppy's first months produce a stack of entries in a short time. Under the AAHA guidelines, puppies receive at least 3 doses of a combination vaccine (distemper, adenovirus, parvovirus) between 6 and 16 weeks of age, 2 to 4 weeks apart, then a single dose within a year of the last one. Leptospirosis is given as two doses 2 to 4 weeks apart starting at 12 weeks, and rabies as required by law. Keep every dated entry, including any vaccines given by a breeder or shelter before adoption, and ask for the product and lot information if it is missing.

Your veterinarian will set the actual schedule for your puppy.

Keeping copies and how long to keep them

• Keep the originals together in one folder: rabies certificates, clinic printouts, the vaccination booklet and any titer reports.
• Keep a digital copy of each page on your phone so you can show it at a front desk or forward it when a groomer asks.
• Keep old records too. There is no single legal retention rule for pet owners, but the full history is what a new veterinarian, a specialist or a travel form may ask about. Keeping it for your dog's lifetime is the simple approach.
• Track due dates separately from the paperwork, so a booster does not lapse the week before a trip or a boarding stay.

Fuzzi Fi can hold this on your phone: log each vaccine with the date given and a booster interval or next due date, see whether it is Up to date, Due Soon or Overdue, and attach photos or PDFs of the certificates to your dog's profile to open or share later.
