Pet Vaccination Schedules: Complete Guide by Species
Vaccinations are one of the most important investments you can make in your pet's health. They prevent deadly diseases, protect other animals in your community, and save thousands of dollars in potential treatment costs. This comprehensive guide covers vaccination schedules for dogs, cats, and other companion animals, including timelines, core vs non-core vaccines, and estimated costs.
Understanding Core vs Non-Core Vaccines
Veterinary vaccines are classified into two categories based on their importance and how widely they are recommended:
Core Vaccines
Core vaccines are recommended for all pets regardless of lifestyle, location, or breed. They protect against diseases that are:
- Highly contagious and widespread in the environment
- Severe or fatal with limited treatment options
- Transmissible to humans (zoonotic), such as rabies
- Required by law (rabies vaccine in most jurisdictions)
Non-Core (Lifestyle) Vaccines
Non-core vaccines are recommended based on your pet's individual risk factors:
- Geographic location and local disease prevalence
- Lifestyle (boarding, dog parks, hiking, travel)
- Exposure risk to wildlife or other animals
- Age and overall health status
Your veterinarian will help determine which non-core vaccines are appropriate for your pet based on these factors.
Puppy Vaccination Schedule (6 Weeks to 16+ Weeks)
Puppies receive maternal antibodies through their mother's milk, but these naturally decline between 6-16 weeks of age. The puppy vaccination series is designed to provide protection as maternal immunity fades. It is critical to complete the full series, as partial vaccination may leave your puppy vulnerable.
| Age | Core Vaccines | Non-Core Vaccines (if recommended) | Notes |
|---|---|---|---|
| 6-8 Weeks | DHPP #1 (Distemper, Hepatitis/Adenovirus, Parainfluenza, Parvovirus) | Bordetella (kennel cough) if boarding/daycare planned | First visit; deworming often included |
| 10-12 Weeks | DHPP #2 | Leptospirosis #1, Lyme #1 (in endemic areas), Canine Influenza #1 | Continue socialization in safe environments |
| 14-16 Weeks | DHPP #3, Rabies (1-year) | Leptospirosis #2, Lyme #2, Canine Influenza #2 | Rabies required by law; can go to dog parks 2 weeks after this visit |
| 12-16 Months | DHPP Booster, Rabies Booster (3-year) | Leptospirosis annual, Bordetella annual, Lyme annual, Canine Influenza annual | Completes the puppy series; establishes adult schedule |
Important: Do NOT take your puppy to dog parks, pet stores, or areas with unknown dogs until 2 weeks after the final DHPP vaccine at 14-16 weeks. Parvovirus is extremely resilient in the environment and can survive for months in soil.
Adult Dog Vaccination Schedule
After completing the puppy series and the 1-year booster, adult dogs transition to a less frequent vaccination schedule. However, some vaccines still require annual boosters. For detailed cost information, see our dog vaccination costs guide.
| Vaccine | Type | Frequency | Protects Against |
|---|---|---|---|
| Rabies | Core | Every 3 years (after initial 1-year vaccine) | Rabies virus; fatal, zoonotic. Required by law. |
| DHPP (DA2PP) | Core | Every 3 years | Distemper, Adenovirus (Hepatitis), Parainfluenza, Parvovirus |
| Bordetella | Non-Core | Every 6-12 months | Kennel cough. Required for boarding, daycare, grooming. |
| Leptospirosis | Non-Core | Annually | Bacterial infection from wildlife urine in water. Zoonotic. |
| Lyme Disease | Non-Core | Annually (in endemic areas) | Borrelia burgdorferi from tick bites. Northeastern, upper Midwestern US. |
| Canine Influenza (H3N2/H3N8) | Non-Core | Annually | Dog flu. Recommended for social dogs, boarding, shows. |
| Rattlesnake Vaccine | Non-Core | Annually (before snake season) | Reduces severity of Western Diamondback rattlesnake bites. |

Kitten Vaccination Schedule (6 Weeks to 16+ Weeks)
Like puppies, kittens receive maternal antibodies that decline during the first months of life. The kitten vaccination series is designed to build immunity as maternal protection fades. For detailed cost information, see our cat vaccination costs guide.
| Age | Core Vaccines | Non-Core Vaccines (if recommended) | Notes |
|---|---|---|---|
| 6-8 Weeks | FVRCP #1 (Feline Viral Rhinotracheitis, Calicivirus, Panleukopenia) | FeLV #1 (Feline Leukemia) for at-risk kittens | First visit; deworming and FeLV/FIV testing often included |
| 10-12 Weeks | FVRCP #2 | FeLV #2 | Continue keeping kitten indoors or in safe environments |
| 14-16 Weeks | FVRCP #3, Rabies (1-year or 3-year depending on jurisdiction) | FeLV booster if outdoor/at-risk | Rabies required by law in most areas |
| 12-16 Months | FVRCP Booster, Rabies Booster | FeLV annual | Completes kitten series; establishes adult schedule |
Adult Cat Vaccination Schedule
| Vaccine | Type | Frequency | Protects Against |
|---|---|---|---|
| Rabies | Core | Every 1 or 3 years (varies by vaccine type and jurisdiction) | Rabies virus; fatal, zoonotic. Required by law. |
| FVRCP | Core | Every 3 years (after initial kitten series + 1-year booster) | Feline Herpesvirus (Rhinotracheitis), Calicivirus, Panleukopenia |
| FeLV (Feline Leukemia) | Non-Core | Annually for at-risk cats | Feline Leukemia Virus. Recommended for outdoor cats, multi-cat households with unknown status. |
| FIV (Feline Immunodeficiency) | Non-Core | Varies; limited availability | Feline Immunodeficiency Virus. Availability and recommendations vary by region. |
| Bordetella | Non-Core | Annually if at risk | Upper respiratory infection. May be required for boarding. |
| Chlamydia felis | Non-Core | Annually if at risk | Bacterial conjunctivitis. Recommended in multi-cat environments with history of outbreaks. |
Important note for indoor cats: Even strictly indoor cats should receive core vaccinations (rabies and FVRCP). Indoor cats can escape, be exposed through screened windows, or encounter viruses carried indoors on shoes and clothing. Rabies vaccination is also legally required in most jurisdictions regardless of indoor/outdoor status.

Vaccinations for Other Species
Rabbits
In the United States, rabbit vaccines have become increasingly important with the arrival of Rabbit Hemorrhagic Disease Virus (RHDV2):
- RHDV2 Vaccine: Highly recommended in areas with confirmed outbreaks. Given at 4+ weeks of age with annual boosters. The disease is often fatal with no effective treatment.
- Myxomatosis Vaccine: Available in the UK and Europe but not currently licensed in the US. Protects against a fatal virus spread by fleas and mosquitoes.
Consult a rabbit-savvy veterinarian for current RHDV2 vaccine availability in your area.
Ferrets
- Canine Distemper Vaccine (Purevax): Core. Given at 8, 11, and 14 weeks, then annually. Distemper is nearly 100% fatal in ferrets.
- Rabies Vaccine (Imrab-3): Core. Given at 12-16 weeks, then annually. Required by law in many jurisdictions.
Note: Ferrets are prone to vaccine reactions. Your vet may recommend pre-treatment with an antihistamine and may ask you to wait 30 minutes after vaccination before leaving the clinic.
Birds
Most pet birds in the US do not receive routine vaccinations. However:
- Polyomavirus Vaccine: Available for psittacines (parrots, budgies, cockatiels). Given at 5 weeks with a booster at 8 weeks. Recommended for breeding aviaries and multi-bird households.
- Avian Pox Vaccine: Available for poultry and some wild birds but not routinely used in pet birds.
Regular wellness exams with an avian veterinarian are more important than vaccinations for most pet birds.
Reptiles
There are currently no commercially available vaccines for pet reptiles. Reptile health management focuses on proper husbandry (temperature, humidity, UVB lighting, nutrition), regular wellness exams with a reptile veterinarian, and parasite screening.
Vaccine Side Effects and What to Watch For
Most pets tolerate vaccinations very well, but it is important to know what to expect and when to contact your veterinarian.
Normal, Mild Side Effects (Resolve in 24-48 Hours)
- Mild lethargy or sleepiness for 1-2 days
- Slightly reduced appetite
- Minor swelling or tenderness at the injection site
- Low-grade fever
- Mild sneezing after intranasal vaccines
Contact Your Vet If You Observe:
- Side effects lasting longer than 48 hours
- Significant swelling at the injection site that grows or persists for weeks
- Persistent vomiting or diarrhea
- Severe lethargy or complete refusal to eat beyond 24 hours
Seek Emergency Care Immediately For:
- Anaphylaxis: Facial swelling, hives, difficulty breathing (rare but serious)
- Collapse or severe weakness
- Persistent vomiting within hours of vaccination
Special Note for Cat Owners
Injection-site sarcomas (FISS) are rare but serious tumors that can develop at vaccine injection sites in cats, particularly with adjuvanted vaccines. Modern protocols recommend administering vaccines in specific limb locations (rather than between the shoulder blades) and using non-adjuvanted vaccines when possible. Discuss vaccine choices and injection sites with your veterinarian.
Frequently Asked Questions
What are core vaccines vs non-core vaccines for pets?
Core vaccines are recommended for all pets regardless of lifestyle because they protect against diseases that are widespread, highly contagious, or fatal. For dogs, core vaccines include rabies, distemper, parvovirus, and adenovirus (DHPP). For cats, core vaccines include rabies, feline panleukopenia, calicivirus, and herpesvirus (FVRCP). Non-core vaccines are recommended based on your pet's lifestyle, geography, and individual risk factors. Your veterinarian will help determine which non-core vaccines are appropriate.
How much do pet vaccinations cost?
Individual vaccine costs typically range from $20-$50 per shot at a regular veterinary clinic. Puppy and kitten series requiring multiple visits can total $200-$500 for the first year. Annual boosters typically cost $50-$200 per year. Low-cost vaccination clinics and mobile clinics may offer vaccines for $10-$25 each. Many pet insurance wellness plans cover routine vaccinations, which can help offset the cost.
Can my puppy go outside before completing all vaccinations?
Puppies should avoid areas with unknown dogs and high dog traffic (dog parks, pet stores, hiking trails) until 2 weeks after their final puppy vaccination at 16 weeks. However, socialization is also critical during this period. Safe socialization options include: visiting homes of vaccinated dogs, carrying your puppy in public areas, attending puppy classes that require vaccination proof, and playing in your own secure, fenced yard.
Do indoor cats need vaccinations?
Yes, indoor cats should receive core vaccinations (rabies and FVRCP). Even strictly indoor cats can be exposed to diseases through screened windows, escaped outings, new pets entering the home, visitors' shoes and clothing, or if they need to be boarded or hospitalized. Rabies vaccination is also legally required in most jurisdictions regardless of indoor/outdoor status.
What are the side effects of pet vaccinations?
Most pets experience no side effects or only mild, temporary reactions including: mild lethargy for 24-48 hours, slight fever, reduced appetite, and minor swelling at the injection site. Serious reactions are rare but can include allergic reactions (facial swelling, hives, difficulty breathing), persistent vomiting, or injection-site sarcoma in cats. Contact your vet immediately if side effects are severe or last more than 48 hours.
How often do adult pets need booster vaccinations?
After completing the initial puppy or kitten series and the 1-year booster, most core vaccines are given every 3 years (rabies, DHPP/FVRCP in their 3-year formulations). Some non-core vaccines like Bordetella, canine influenza, and leptospirosis require annual boosters. Your veterinarian will recommend a personalized schedule based on your pet's specific risk factors, local disease prevalence, and legal requirements in your jurisdiction.
