Wondering how often should a pet be vaccinated? Learn the best vaccination schedule for dogs and cats to keep them healthy and safe.
Vaccinations are essential for keeping your pet healthy and protecting them from serious diseases. However, pet owners often wonder, “How often should a pet be vaccinated?” The answer depends on factors like age, lifestyle, health status, and local regulations.
This guide will explain which vaccines are necessary, how frequently they should be administered, and why they are important for your pet’s well-being.
Why Are Pet Vaccinations Important?
Vaccines help prevent infectious diseases that can be fatal or cause serious health complications. They stimulate your pet’s immune system to recognize and fight harmful viruses and bacteria.
Benefits of Vaccination:
✅ Protects pets from deadly diseases like rabies and distemper
✅ Prevents the spread of contagious infections
✅ Saves money by avoiding costly treatments for preventable illnesses
✅ Ensures compliance with legal requirements for pet ownership
✅ Protects humans from zoonotic diseases (those that can spread from animals to people)
By staying up to date with vaccinations, you can give your pet a long, healthy, and happy life.

Types of Pet Vaccines
Pet vaccines are divided into core and non-core (optional) vaccines based on their necessity.
Core Vaccines (Essential for All Pets)
These vaccines are required for all pets because they protect against highly contagious and often fatal diseases.
For Dogs:
- Rabies – Legally required in most places; prevents a fatal virus that affects the nervous system.
- Canine Distemper – A deadly virus affecting the respiratory, digestive, and nervous systems.
- Parvovirus (Parvo) – A highly contagious virus causing severe vomiting, diarrhea, and dehydration.
- Adenovirus (Hepatitis) – Causes liver disease and respiratory infections.
For Cats:
- Rabies – Mandatory in most areas to prevent the spread of this deadly virus.
- Feline Distemper (Panleukopenia) – A severe viral infection affecting the immune and digestive systems.
- Feline Calicivirus – A major cause of upper respiratory infections.
- Feline Herpesvirus (Rhinotracheitis) – Causes respiratory issues, eye infections, and fever.
Non-Core Vaccines (Recommended Based on Lifestyle)
These vaccines are optional but necessary depending on your pet’s environment and risk exposure.
For Dogs:
- Bordetella (Kennel Cough) – Recommended for dogs that socialize, go to daycare or visit dog parks.
- Leptospirosis – Important for dogs exposed to water, wildlife, or farms.
- Lyme Disease – Suggested for dogs in areas with high tick populations.
- Canine Influenza (Dog Flu) – Beneficial for dogs frequently in contact with other dogs.
For Cats:
- Feline Leukemia (FeLV) – Recommended for outdoor cats or those in multi-cat households.
- Chlamydia – Prevents respiratory and eye infections in cats.
Consult your veterinarian to determine which non-core vaccines are necessary for your pet.
Vaccination Schedule for Dogs and Cats
Puppy & Kitten Vaccination Schedule (First Year)
Young pets receive a series of vaccines to build strong immunity.
| Age | Dog Vaccinations | Cat Vaccinations |
|---|---|---|
| 6-8 weeks | Distemper, Parvo | Feline Distemper, Calicivirus, Herpesvirus |
| 10-12 weeks | Distemper, Parvo, Adenovirus, Leptospirosis (if needed) | Feline Leukemia (if needed) |
| 12-16 weeks | Rabies (Required by law), Bordetella (if needed) | Rabies (Required by law), Feline Leukemia (booster) |
| 16-20 weeks | The final round of core vaccines | The final round of core vaccines |
Why multiple doses? Puppies and kittens receive immunity from their mother’s milk, but this fades over time. Booster shots ensure they develop long-lasting immunity.
Adult Dog & Cat Vaccination Schedule
Once the initial series is complete, pets need regular booster shots to maintain protection.
| Vaccine | Frequency for Dogs | Frequency for Cats |
|---|---|---|
| Rabies | Every 1-3 years (depending on local laws) | Every 1-3 years (as required by law) |
| Distemper, Parvo, Adenovirus | Every 1-3 years | Every 1-3 years |
| Bordetella (Kennel Cough) | Every 6-12 months (if social) | Not needed |
| Leptospirosis | Yearly (for at-risk dogs) | Not needed |
| Lyme Disease | Yearly (for dogs in tick-prone areas) | Not needed |
| Feline Leukemia (FeLV) | Not needed | Every 1-2 years (for at-risk cats) |
What Happens If You Miss a Vaccine?
If your pet misses a scheduled vaccine, their protection may weaken.
🚨 What to do:
- If a vaccine is overdue by a few weeks, a booster shot may be sufficient.
- If several months or years have passed, your pet may need to restart the series.
- Rabies vaccines must be up to date to comply with the law. An unvaccinated pet may face quarantine if they bite someone.
Always check with your vet if your pet has missed a vaccine.

Frequently Asked Questions (FAQs)
How do I know if my pet needs non-core vaccines?
Non-core vaccines are based on your pet’s lifestyle, environment, and health risks. If your pet is outdoors often, socializes with other animals, or travels, they may need extra protection.
Are vaccines safe for pets?
Yes! Vaccines undergo strict testing to ensure safety and effectiveness. Some pets may have mild side effects (like slight swelling or tiredness), but serious reactions are rare.
Can an indoor cat skip vaccines?
Even indoor cats need core vaccines like rabies and distemper because diseases can spread through air, objects, or human contact. Non-core vaccines (like FeLV) may not be necessary if they never go outside.
What are the side effects of vaccines?
Common side effects include:
- Mild fever
- Soreness at the injection site
- Temporary tiredness
Severe reactions (swelling, vomiting, breathing issues) are rare but require immediate vet attention.
Can older pets stop getting vaccines?
Senior pets still need vaccinations but may require fewer boosters based on their health. A veterinary checkup can determine the best vaccination plan.
Final Thoughts
Regular vaccinations are one of the best ways to keep your pet healthy and prevent life-threatening diseases. Whether your pet is a puppy, kitten, or senior, keeping up with their vaccination schedule ensures a longer, healthier life.
