When Do We Vaccinate

Puppy Vaccination Schedule: Protecting Your Puppy from Day One

Bringing home a new puppy is an exciting milestone. Along with all the cuddles, training, and playtime comes one of the most important responsibilities of puppy ownership: vaccinations.

Puppies are born with some protection from their mother’s antibodies, but that immunity begins to fade within the first few weeks of life. Vaccinations help build your puppy’s immune system and protect them from serious, potentially life-threatening diseases.

In this guide, we’ll explain the recommended puppy vaccination schedule, the types of vaccines available, and why each one is important.

Why Are Puppy Vaccinations Important?

Puppies have developing immune systems that leave them vulnerable to infectious diseases. Many of these illnesses can spread rapidly through contact with other dogs, contaminated environments, or even wildlife.

Vaccinations help:

• Prevent serious illness and death

• Reduce veterinary treatment costs

• Protect other pets in the community

• Support overall public health

• Ensure your puppy can safely participate in training classes, daycare, boarding, and social activities

Core vs. Non-Core Vaccines

Vaccines are generally divided into two categories:

Core Vaccines

Core vaccines are recommended for all puppies regardless of breed, lifestyle, or location because they protect against widespread and dangerous diseases.

These include:

• Distemper

• Parvovirus

• Adenovirus (Canine Hepatitis)

• Rabies

Non-Core Vaccines

Non-core vaccines are recommended based on your puppy’s lifestyle, exposure risk, and geographic location.

These may include:

• Bordetella (Kennel Cough)

• Leptospirosis

• Canine Influenza

• Lyme Disease

• Rattlesnake Vaccine (in certain regions)

Your veterinarian can help determine which non-core vaccines are appropriate for your puppy.

Recommended Puppy Vaccination Schedule

6–8 Weeks of Age

DHPP Vaccine (First Dose)

Protects against:

• Distemper

• Hepatitis (Adenovirus)

• Parvovirus

• Parainfluenza

Why it’s important:

These diseases can cause severe respiratory, neurological, gastrointestinal, and liver complications. Parvovirus, in particular, is highly contagious and often fatal in young puppies.

Bordetella Vaccine (Optional)

Protects against:

• Bordetella bronchiseptica, a common cause of kennel cough

Why it’s important:

Recommended for puppies that may attend daycare, training classes, boarding facilities, grooming salons, or dog parks.

10–12 Weeks of Age

DHPP Vaccine (Second Dose)

A booster helps strengthen immunity as maternal antibodies continue to decline.

Leptospirosis Vaccine (First Dose)

Protects against:

• Leptospira bacteria

Why it’s important:

Leptospirosis can damage the liver and kidneys and can be transmitted to humans. It is commonly spread through contaminated water, wildlife, and standing puddles.

Canine Influenza Vaccine (First Dose – Risk Based)

Protects against canine flu strains.

Why it’s important:

Useful for puppies frequently exposed to other dogs in social settings.

14–16 Weeks of Age

DHPP Vaccine (Final Puppy Booster)

This final puppy booster helps ensure long-lasting protection.

Rabies Vaccine

Protects against:

• Rabies virus

Why it’s important:

Rabies is fatal and can be transmitted to humans and other animals. Vaccination is required by law in most states.

Leptospirosis Booster

Required to complete the initial protection series.

Canine Influenza Booster

Completes the initial vaccine series if recommended.

12–16 Weeks of Age (Risk-Based)

Lyme Disease Vaccine

Recommended for puppies living in or traveling to areas with high tick populations.

Protects against:

• Borrelia burgdorferi bacteria

Why it’s important:

Lyme disease can cause joint pain, fever, and kidney complications.

After the Puppy Stage

One Year of Age

Most puppies will receive:

• DHPP Booster

• Rabies Booster

• Leptospirosis Booster (if applicable)

• Bordetella Booster (if applicable)

• Canine Influenza Booster (if applicable)

After the first-year booster, many vaccines are administered every one to three years depending on the vaccine type and local regulations.

Vaccination Tips for New Puppy Owners

Limit Exposure Before Full Vaccination

Until your puppy has completed their vaccine series, avoid:

• Dog parks

• Public dog areas

• Unknown dogs

• Standing water sources

Safe socialization can still occur with healthy, fully vaccinated dogs in controlled environments.

Keep Records Organized

Maintain a copy of all vaccination records. You’ll need them for:

• Boarding facilities

• Groomers

• Dog daycare programs

• Training classes

• Travel requirements

Watch for Mild Side Effects

Most puppies experience little to no reaction. Mild effects may include:

• Sleepiness

• Mild soreness at the injection site

• Temporary decrease in appetite

Contact your veterinarian immediately if you notice:

• Facial swelling

• Difficulty breathing

• Persistent vomiting

• Severe lethargy

Final Thoughts

Vaccinations are one of the most effective ways to give your puppy a healthy start in life. Following a veterinarian-recommended vaccination schedule helps protect against dangerous diseases while allowing your puppy to safely explore the world around them.

Every puppy’s lifestyle is unique, so work closely with your veterinarian to determine which core and non-core vaccines are best suited for your dog’s needs. A little prevention today can help ensure many happy, healthy years together tomorrow.
