Cat & Dog Vaccination Schedule (2026)

Why vaccines still matter

Vaccines do quiet, unglamorous work: they teach a pet's immune system to recognize a disease before it ever shows up. The diseases they prevent are not rare or abstract. Parvovirus can kill a puppy in days. Distemper is often fatal. Rabies is fatal in essentially all cases — and because it can spread to people, it's the one shot the law actually requires in most of the country.

For a new puppy or kitten, that first round of shots is the single most protective thing you'll buy in their first year. It's also the reason the early vet visits are worth every dollar, a topic we'll get to below.

Core vs. non-core shots

Core vaccines are recommended for nearly every pet because the diseases are widespread, severe, or transmissible to humans. For dogs, the core set covers rabies plus distemper, parvovirus, and adenovirus (often combined in one "DHPP" shot). For cats, it's rabies plus FVRCP, which protects against feline viral rhinotracheitis, calicivirus, and panleukopenia.

Non-core vaccines are given based on lifestyle and risk. A dog who's boarded or groomed often may be offered Bordetella (kennel cough), and one who hikes tick country might get a Lyme vaccine. An outdoor cat may be offered feline leukemia. These aren't "optional because they don't matter" — they're optional because not every pet is exposed. Your vet decides based on how your pet actually lives.^[1]

The puppy & kitten series

Young animals get a series rather than one-and-done because the antibodies they got from their mother's milk can interfere with early vaccines. By repeating the shots every 3–4 weeks, vets make sure protection "takes." The series typically starts around 6–8 weeks and runs until about 16 weeks, then a booster at roughly a year. Here's the general shape:

Your vet may compress or shift these dates based on the brand of vaccine and your pet's risk. The exact weeks matter less than the rhythm: a series, spaced a few weeks apart, finishing with a booster around the first birthday.

Adult boosters

After that first-year booster, most core vaccines shift to a slower schedule. Rabies boosters are often every one to three years depending on the vaccine and local law. DHPP and FVRCP boosters are commonly given every one to three years too, guided by your vet and sometimes by antibody tests. Non-core shots like Bordetella may need yearly top-ups, especially for dogs who board or visit daycare.

The key is not to let boosters slide off your radar entirely. A lapsed vaccine leaves a gap that a single booster visit can close — so keep the reminders on, and ask your vet at the annual checkup what's actually due.

What it costs

Vaccine costs are usually baked into a routine visit. A basic exam runs roughly $50–$150,^[2] and a routine dog visit averages around $214 while a cat visit averages around $138.^[2] Across the year, owners spend an average of about $598 on vet care for a dog and $529 for a cat.^[3] The vaccine itself is often the cheaper part — it's the exam and the time that make up the bill, which is exactly why that exam is worth it.

FAQ

Is rabies vaccination really required by law?

In most US states and many countries, yes. Rabies is almost always fatal once symptoms appear and it can spread to people, so keeping that shot current is both a legal and a safety matter. Your vet knows your local rules.

Can I skip non-core vaccines to save money?

Sometimes, but only if your pet's lifestyle genuinely doesn't call for them. A strictly indoor cat may not need feline leukemia, for instance. Ask your vet which non-core shots your pet's routine actually justifies rather than cutting them blindly.

What if I miss a booster?

Don't panic — just book the visit. Depending on how far you've overshot and which vaccine it is, your vet may restart the series or simply give the booster. The sooner you close the gap, the simpler it is.
