Pet Vaccination Schedule Calculator

A well-planned pet vaccination schedule protects your dog or cat from serious and potentially life‑threatening infectious diseases. Core vaccines—such as DHPP and Rabies in dogs or FVRCP and Rabies in cats—offer broad, foundational protection against common pathogens with significant public health implications. Non‑core vaccines, including Bordetella, Leptospirosis, and FeLV, are recommended based on lifestyle, geography, and individual risk factors. While vaccination guidelines share themes worldwide, the exact timing, labeling, and legal requirements can vary meaningfully by country, state, and municipality. That’s why your licensed veterinarian remains the best authority on what to give and when to give it.

This calculator provides an educational, heuristic timeline for upcoming shots based on species, birth date, and country. For puppies and kittens, pediatric series often begin around 8 weeks, continue every 3–4 weeks until approximately 16–20 weeks, and include a Rabies vaccination once the local minimum age is met. Following the initial series, many core vaccines are boosted at the one‑year mark and then administered every 1–3 years depending on product label and regional regulations. For adult pets with unknown vaccine histories, veterinarians may recommend a restart protocol or antibody titers in select scenarios, balancing disease risk, travel plans, and public health rules.

Remember that a schedule is only part of preventive care. Veterinary teams evaluate your pet’s medical record, environment, and temperament to tailor a plan. Boarding, daycare, grooming, dog parks, multi‑pet households, wildlife exposures, and international travel can all influence non‑core vaccine recommendations. Additionally, certain medical conditions or prior adverse events may alter timing or brand selection. Always discuss your pet’s unique needs—including any upcoming moves or trips—with your vet. This tool is not medical advice or a substitute for a physical examination.

Finally, keep accurate records. Many regions require proof of Rabies vaccination for licensing and travel, and shelters, trainers, or groomers may request documentation for Bordetella or other vaccines. Digital copies and reminders can help you stay on time, especially during the first 18 months when due dates arrive quickly. If you miss a window, don’t panic—contact your clinic to plan a catch‑up sequence. Your veterinary team will ensure your pet returns to an effective protection level as safely and efficiently as possible.
