Dog & Cat Vaccine Schedule 2026: When, What & How Much

Vaccination Is the Foundation of Your Pet’s Health

Vaccines are the single most reliable way to protect your pet from life-threatening infectious diseases. Yet many pet owners aren’t entirely sure about when each vaccine is due or which ones their pet actually needs.

This guide breaks down the vaccine schedules for both dogs and cats, along with practical tips for managing records and watching for side effects.

Dog Vaccine Schedule

Rabies Vaccine (Required by Law in Many Regions)

Who needs it: All dogs, typically required by local or national law
First dose: Usually administered between 12 and 16 weeks of age
Boosters: Every 1 to 3 years depending on local regulations and vaccine type
Check your local requirements — in many jurisdictions, proof of rabies vaccination is legally mandatory

Core Combination Vaccines (Highly Recommended)

Commonly referred to as DHPP (Distemper, Hepatitis, Parainfluenza, Parvovirus) or similar combinations
Puppies: Start at 6-8 weeks old, with boosters every 3-4 weeks until 16 weeks of age
Adult dogs: One booster at 1 year after the puppy series, then every 1-3 years depending on the vaccine

Core vaccines protect against: Distemper, Parvovirus, Adenovirus (Hepatitis), and Parainfluenza.

Non-Core Vaccines (Based on Lifestyle)

Bordetella (kennel cough): Recommended for dogs that visit boarding facilities, dog parks, or grooming salons
Leptospirosis: Recommended in areas where wildlife exposure is common
Canine Influenza: May be required by boarding facilities
Discuss your dog’s specific risk factors with your veterinarian

Cat Vaccine Schedule

FVRCP — Core Vaccine

Protects against: Feline Viral Rhinotracheitis, Calicivirus, and Panleukopenia
Kittens: Start at 6-8 weeks, with boosters every 3-4 weeks until 16 weeks of age
Adult cats: Booster at 1 year, then every 1-3 years

Rabies Vaccine

Required by law in many areas, even for indoor-only cats
First dose: Typically at 12-16 weeks of age
Boosters: Every 1-3 years depending on the vaccine used and local regulations

Feline Leukemia Virus (FeLV) — Non-Core

Recommended for: Outdoor cats, cats in multi-cat households, or cats exposed to unknown cats
Schedule: Two initial doses 3-4 weeks apart, then annual boosters
For strictly indoor cats with no exposure risk, discuss with your vet whether this vaccine is necessary

What to Watch for After Vaccination

Monitor your pet for 24-48 hours after any vaccination:

Mild reactions (common): Slight lethargy, reduced appetite, mild swelling at the injection site. These typically resolve within 1-2 days
Serious reactions (rare): Facial swelling, vomiting, difficulty breathing, collapse. Contact your veterinarian immediately if you observe any of these
Avoid strenuous exercise and bathing on the day of vaccination

Why Keeping Vaccination Records Matters

Vaccination records come up more often than you might expect:

Boarding and daycare: Most facilities require proof of current vaccinations
Changing veterinarians: Your new vet needs a complete vaccination history to avoid unnecessary re-vaccination
Knowing when the next dose is due: Without records, you’re guessing — and guessing can mean your pet goes unprotected

Paper vaccination cards are easy to lose and hard to find when you need them most. Digital records that you can pull up on your phone are far more practical.
