Understanding Puppy Vaccinations: What Shots They Need & When
Vaccinations are one of the most important steps in keeping your puppy healthy. They protect against deadly diseases like parvovirus, distemper, and rabies—all of which can be fatal if left untreated.
As a new puppy owner, you might be asking:
• What vaccines does my puppy need?
• When should my puppy get shots?
• Are there optional vaccines my puppy should get?
This guide breaks down the puppy vaccination schedule, explains the difference between core and non-core vaccines, and answers common questions about puppy shots.
Why Are Puppy Vaccinations Important?
Puppies are born with some protection from their mother’s antibodies, but this immunity fades within 6-8 weeks. Without vaccines, they become highly vulnerable to deadly diseases.
Benefits of Puppy Vaccinations:
Prevents life-threatening illnesses like parvo and distemper
Protects other dogs by reducing the spread of contagious diseases
Saves money—treating preventable diseases can cost thousands in vet bills
Keeps your puppy safe when socializing with other dogs
By following a proper vaccination schedule, you can ensure your puppy grows into a healthy, happy adult dog.
Core Vaccines vs. Non-Core Vaccines
Not all vaccines are required for every puppy. Veterinarians divide them into core and non-core vaccines based on risk factors and disease severity.
Core Vaccines (Required for All Puppies)
These vaccines protect against the most dangerous and widespread diseases. Every puppy needs them, regardless of breed or lifestyle.
Distemper – A deadly virus affecting the nervous, respiratory, and digestive systems
Parvovirus (Parvo) – A highly contagious virus that causes severe vomiting, diarrhea, and dehydration
Adenovirus (Hepatitis) – Causes liver and kidney damage, often fatal
Rabies – A fatal disease that affects the nervous system; required by law in most areas
Non-Core Vaccines (Optional, Based on Risk Factors)
These vaccines are recommended based on your puppy’s environment, lifestyle, and exposure risk.
Bordetella (Kennel Cough) – Required for boarding, grooming, or dog parks
Leptospirosis – Recommended for puppies in rural or farm areas
Canine Influenza (Dog Flu) – Ideal for dogs frequently around other dogs
Lyme Disease – Needed if you live in a tick-heavy area
Your veterinarian will help determine if your puppy needs these non-core vaccines.
Puppy Vaccination Schedule: What Shots They Need & When
Puppies receive a series of vaccines over their first few months to build strong immunity. Here’s the typical vaccination schedule:
8 Weeks Old (First Round)
- DHPP (Distemper, Hepatitis, Parvovirus, Parainfluenza)
- Bordetella (if needed)
12 Weeks Old (Second Round)
-DHPP Booster
-Leptospirosis (if needed)
-Canine Influenza (if needed)
16 Weeks Old (Final Puppy Shots)
-DHPP Booster
-Rabies (Required by law in most states)
-Lyme Disease (if needed)
6-12 Months Old (Final Boosters)
DHPP Booster (final dose)
Bordetella Booster (if needed)
After this, adult dogs need booster shots every 1-3 years, depending on the vaccine.
Are Puppy Vaccines Safe?
Yes! Veterinary-approved vaccines are safe and essential for your puppy’s health. However, like any medical treatment, vaccines can have mild side effects.
Common Mild Side Effects (24-48 Hours):
• Slight lethargy or tiredness
• Mild swelling at the injection site
• Low-grade fever
• Temporary loss of appetite
These effects usually go away within a day. If your puppy has severe reactions like swelling, difficulty breathing, or persistent vomiting, contact your vet immediately.
Frequently Asked Questions About Puppy Vaccines
1. Can I Take My Puppy Outside Before Vaccines Are Complete?
Puppies shouldn’t be exposed to high-risk areas (like dog parks, pet stores, or boarding facilities) until they’ve had all three rounds of shots (usually around 16 weeks).
However, you can:
- Carry your puppy outside for fresh air and potty training
- Let them explore your backyard or enclosed area
- Socialize with fully vaccinated dogs in a safe setting
2. What Happens If My Puppy Misses a Vaccine?
If your puppy misses a scheduled vaccine, call your vet to reschedule as soon as possible. Missing a dose delays immunity and increases disease risk.
3. Are Puppy Vaccines Required by Law?
- Rabies vaccinations are required by law in most states. Failure to vaccinate can lead to fines or legal consequences.
- Core vaccines (Distemper, Parvo, Adenovirus) aren’t legally required but are highly recommended by vets.
4. How Much Do Puppy Vaccinations Cost?
Prices vary based on location and vet clinic, but here’s a general estimate:
• Individual vaccines: $20 - $40 each
• Full puppy vaccine series: $75 - $200
• Rabies vaccine: $15 - $30 (often required by law)
Low-cost vaccination clinics and pet shelters often provide affordable options.
5. Do Adult Dogs Need Booster Shots?
Yes! After completing puppy vaccinations, dogs need boosters every 1-3 years to maintain immunity.
- Rabies: Every 1-3 years (depending on state laws)
- DHPP: Every 1-3 years
- Bordetella, Lepto, Lyme, and Influenza: Yearly (if needed)
Your vet will recommend a custom vaccination plan based on your dog’s lifestyle.
