Complete Dog Vaccination Schedule

Protect your puppy and adult dog from life-threatening diseases with the complete vaccination schedule. Learn when your dog needs each vaccine, why boosters are important, and how vaccinations help your pet live a long, healthy, and happy life.

Why Dog Vaccination is Important

Vaccination is one of the most effective ways to protect dogs from serious infectious diseases. Puppies are born with temporary immunity received from their mother's milk, but this protection gradually disappears after a few weeks. Vaccines help build strong immunity before your puppy is exposed to dangerous viruses and bacteria.

Following a proper vaccination schedule significantly reduces the risk of diseases such as Canine Parvovirus, Distemper, Hepatitis, Parainfluenza, Leptospirosis, and Rabies. Regular booster vaccinations continue protecting adult dogs throughout their lives.

Did You Know?

Vaccination has saved millions of dogs worldwide by preventing deadly infectious diseases that once had very high mortality rates.

Benefits of Vaccinating Your Dog

🛡 Disease Protection

  • Prevents life-threatening infections
  • Builds strong immunity
  • Protects puppies during growth
  • Reduces disease transmission
  • Supports long-term health

❤️ Better Quality of Life

  • Reduces medical emergencies
  • Lowers treatment costs
  • Supports healthy development
  • Allows safe socialization
  • Provides peace of mind
Veterinarian Recommendation: Puppies should begin vaccinations between 6–8 weeks of age. Never skip booster doses because they are essential for developing complete immunity.

Diseases Prevented by Vaccination

Modern canine vaccines protect dogs from several highly contagious diseases that can spread quickly through direct contact, contaminated environments, or infected animals.

Core Diseases

  • Canine Parvovirus
  • Canine Distemper
  • Infectious Canine Hepatitis
  • Parainfluenza
  • Rabies

Additional Protection

  • Leptospirosis
  • Bordetella (Kennel Cough)
  • Canine Influenza
  • Lyme Disease
  • Coronavirus (where recommended)

Before Your Puppy's First Vaccination

  • Ensure your puppy is healthy.
  • Deworm as advised by your veterinarian.
  • Feed a balanced puppy diet.
  • Keep your puppy well hydrated.
  • Avoid contact with unknown dogs.
  • Do not take puppies to public parks before vaccination.

How Vaccines Work

Vaccines contain weakened or inactive forms of disease-causing organisms. They stimulate your dog's immune system to produce protective antibodies without causing the actual disease. If your dog is exposed to the infection later, the immune system can respond quickly and prevent serious illness.

Puppies require multiple vaccinations because maternal antibodies gradually disappear. Booster doses ensure long-lasting immunity during this important growth period.

Complete Puppy Vaccination Schedule

Following a proper vaccination schedule is essential for building strong immunity during your puppy's early months. Puppies are most vulnerable to infectious diseases between 6 and 16 weeks of age, making timely vaccination extremely important.

Important: Always follow your veterinarian's recommended vaccination schedule. Delaying vaccinations may leave your puppy unprotected against serious diseases.
Puppy Age Recommended Vaccine Purpose
6–8 Weeks DHPP (1st Dose) Protects against Distemper, Hepatitis, Parvovirus & Parainfluenza
9–10 Weeks DHPP Booster + Leptospirosis Strengthens immunity
12 Weeks DHPP Booster + Leptospirosis Booster Long-term protection
14–16 Weeks Rabies Vaccine Protects against Rabies
6 Months Optional Bordetella / Kennel Cough Recommended for social dogs
12 Months Annual Booster Maintains immunity
Your veterinarian may recommend additional vaccines depending on your dog's breed, lifestyle, travel history, and disease risk in your area.
