Vaccination Schedules for Puppies & Kittens

Ensure lifelong protection: a complete, research-based guide to the essential vaccines your puppy or kitten needs and when to give them.

Vaccinations are one of the most important foundations of preventive care for puppies and kittens. Since young animals have immature immune systems and can be vulnerable to serious — sometimes fatal — diseases, following a proper vaccine schedule is critical for their health and survival. This guide breaks down the most current recommendations, explains what each vaccine protects against, and gives you a clear, practical timeline you can follow with your veterinarian. WebMD+1

🐶 Why Vaccination Matters in Young Pets

From the moment a puppy or kitten is born, they rely initially on maternal antibodies passed through their mother’s milk to protect them. Those antibodies gradually wane over time, which is why vaccines must be given during a specific window to stimulate the young animal’s immune system before they become vulnerable. wsava.org

Proper vaccination:

• Prevents serious infectious diseases

• Reduces the spread of contagious illnesses to other pets

• Improves overall health and longevity

• May be a legal requirement in your country (e.g., rabies) WebMD

🐾 Core vs. Non-Core Vaccines

Vaccines are usually categorized into core and non-core types:

• Core vaccines: Recommended for all puppies or kittens because they protect against widespread, serious diseases.

• Non-core vaccines: Given based on lifestyle, environment, and individual risk (e.g., outdoor exposure, boarding, kennel settings). WebMD

📅 Standard Vaccination Schedule for Puppies

Most veterinarians worldwide follow a vaccine timeline for puppies that begins at 6–8 weeks of age, with booster shots every 3–4 weeks until about 16 weeks of age. The final dose must not be given earlier than 16 weeks to ensure full immunity. wsava.org

Typical Puppy Vaccination Timeline:

Age	Vaccine(s)
6–8 weeks	First core combination (DHPP: Distemper, Adenovirus/Hepatitis, Parvovirus, Parainfluenza)
10–12 weeks	DHPP booster (and sometimes first non-core vaccines like Bordetella if risk is high)
14–16 weeks	Final DHPP booster + Rabies vaccine
12–16 months	DHPP + Rabies booster
Every 1–3 years	Ongoing boosters based on risk and local veterinary guidelines

⚠️ Optional non-core vaccines (based on lifestyle/exposure):

• Bordetella (kennel cough)

• Leptospirosis

• Lyme disease

• Canine influenza WebMD+1

🐱 Standard Vaccination Schedule for Kittens

Kittens follow a similar structure to puppies, with vaccination series beginning early and repeated at regular intervals to ensure full immune protection before maternal antibodies fade. WebMD

Typical Kitten Vaccination Timeline:

Age	Vaccine(s)
6–8 weeks	First core combo (FVRCP: Feline Viral Rhinotracheitis, Calicivirus, Panleukopenia)
10–12 weeks	FVRCP booster ± FeLV (Feline Leukemia Virus, if at risk)
14–16 weeks	Final FVRCP booster + Rabies vaccine
12–16 months	FVRCP + Rabies booster (and FeLV if needed)
Every 1-3 years	Continued boosters based on lifestyle and veterinary advice

⚠️ Non-core vaccines may include:

• FeLV (especially for outdoor or multi-cat households)

• Bordetella

• Chlamydia (often in high-density cat environments) WebMD+1

🧠 Understanding the Core Vaccines

Here’s what each core vaccine protects against:

🐶 Puppies

• Distemper: A severe viral disease affecting respiratory, gastrointestinal, and nervous systems.

• Parvovirus (Parvo): Highly contagious, often fatal, causing severe vomiting and diarrhea.

• Adenovirus/Hepatitis: Affects liver and can lead to serious organ damage.

• Parainfluenza: Often part of combination vaccines; contributes to respiratory disease.

• Rabies: Fatal disease with public-health importance; legally required in most countries. WebMD

🐱 Kittens

• Feline Viral Rhinotracheitis (FHV-1): Respiratory disease that can be severe.

• Calicivirus: Another respiratory virus, sometimes causes oral ulcers and fever.

• Panleukopenia (FPV): Often called feline distemper, this is highly contagious and life-threatening.

• Rabies: Fatal to cats and poses zoonotic risk; vaccination is often required by law. WebMD

📌 Why Timing and Boosters Matter

Vaccines are most effective when administered in a series rather than a single shot. This is because:

• Maternal antibodies can interfere with early vaccinations.

• Multiple doses strengthen immune memory.

• Boosters ensure lasting protection. wsava.org

Skipping doses or delaying vaccinations can leave your puppy or kitten vulnerable to disease, especially in environments where infections are common.

🩺 What to Expect After Vaccination

Most pets handle vaccinations well with minimal side effects, such as:

• Mild fever

• Some lethargy

• Temporary soreness at the injection site

These symptoms typically resolve within 24–48 hours. If your pet shows severe symptoms — such as vomiting, difficulty breathing, or swelling — contact a veterinarian immediately. rpets.in

🧭 Adult and Long-Term Vaccination Needs

Once your puppy or kitten completes the initial series:

• Core vaccines may be boosted every 1–3 years depending on type and local regulations.

• Rabies boosters are usually on a 1- to 3-year cycle, depending on vaccine type and legal requirements.

• Non-core vaccines may require annual boosters based on your pet’s lifestyle and exposure risk. WebMD

🐾 Final Tips for Responsible Pet Vaccination

✅ Start early: Begin vaccinations at 6–8 weeks of age.
✅ Follow a schedule: Don’t skip boosters — they’re essential for immunity.
✅ Consult your vet: Schedules may vary by region and individual risk.
✅ Keep records: Maintain an organized vaccination log for your pet.
✅ Tailor to lifestyle: Indoor and outdoor pets may have different needs. Ark Veterinary Hospital & Urgent Care
