Vaccines are like little warriors that fight off nasty diseases. The same goes for your puppy vaccination—since their immune system isn’t fully developed yet, they need extra protection from serious illnesses that can make them very sick or even lead to death.
Vaccines help protect your puppy from dangerous diseases like parvo, distemper, and rabies. Getting your puppy vaccinated on time is one of the best things you can do as a dog owner.
But many people aren’t sure when their puppy needs shots, which vaccines are essential, or how often they should get them. Don’t worry! We’ll explain everything step by step to help you keep your puppy healthy and safe.
What Are Vaccines and How Do They Work?
Vaccines are those pratcir drills for your puppy’s immune system. They are the ones to help your puppy learn how to fight off harmful diseases without actually getting sick. When your puppy gets a vaccine, it contains a weak or harmless part of a virus or bacteria that helps your body to defend itself.
Mainly for those serious illnesses like parvo, distemper, rabies, and hepatitis. Some vaccines are called “core vaccines,” and they are essential for every puppy, no matter where they live. These include vaccines for parvovirus, distemper, hepatitis, and rabies. Other vaccines are called “non-core vaccines,” and they are only given if your puppy is at risk based on things like location or lifestyle—such as if your puppy is often around other dogs or lives near water.
Moreover, some vaccines need booster shots later to keep your puppy’s protection strong. While your puppy might feel a little sore or tired after a shot, that means the vaccine is working. Getting your puppy vaccinated on time is one of the best ways to help them stay healthy and safe.
First Vet Visit: What to Expect
Your puppy’s first vet visit typically happens between 6 to 8 weeks of age. During this visit, the vet will perform a general health check to ensure your puppy is growing well and doesn’t have any underlying health issues. The vet will also discuss your puppy’s diet, behavior, and care routines, as well as give the first round of vaccinations. You’ll receive advice on parasite control, such as treatments for worms and fleas, and the importance of early socialization. Additionally, the vet will discuss optional vaccines based on your puppy’s lifestyle and the area in which you live.
| Age | Vaccines Given |
| 6–8 Weeks | First shot: Distemper, Parvovirus (usually combined in one vaccine). Bordetella (for kennel cough) might be given if needed. |
| 10–12 Weeks | Second shot: DHPP (Distemper, Hepatitis, Parainfluenza, Parvovirus). Optional vaccines like Bordetella, Leptospirosis, Lyme, or Influenza may be given. |
| 14–16 Weeks | Final puppy vaccine: DHPP booster and Rabies (required by law in many places). Optional vaccines like Bordetella, Leptospirosis, or Lyme may be given. |
Core Vaccines
These vaccines are essential for every puppy:
- Distemper: A serious disease that affects the respiratory, digestive, and nervous systems.
- Parvovirus: A highly contagious virus that causes severe vomiting and diarrhea.
- Adenovirus (Hepatitis): Protects against a viral liver disease.
- Parainfluenza: A respiratory illness often included in combination vaccines.
- Rabies: A deadly viral disease that is required by law in many places after 14 weeks of age.
Optional Vaccines
These vaccines depend on your puppy’s lifestyle and environment:
- Bordetella bronchiseptica: Protects against kennel cough and is recommended for dogs in places with many other dogs (boarding, daycare, etc.).
- Leptospirosis: A bacterial infection that affects the liver and kidneys, often transmitted through water or animal urine.
- Lyme Disease: Given to puppies in or traveling to areas with ticks.
- Canine Influenza: Affects the respiratory system; often given to puppies in high-risk environments.
- Coronavirus: A viral infection that can cause gastrointestinal issues, but it’s less commonly used.
Adolescent Vaccinations (4–6 Months)
When your puppy is around 4 to 6 months old, it’s time for some important vaccinations. These include a required rabies shot and booster doses of earlier vaccines to ensure your dog stays healthy and protected as it grows.
| Vaccine | Age Given | Notes |
| Rabies | Around 4 months | Required by law in most places |
| DHPP Booster | 4–6 months | Reinforces immunity to serious diseases |
| Optional Vaccines | 4–6 months | Given based on risk (outdoor life, location, etc.) |
| Next Booster | 12 months+ | Then every 1 to 3 years as recommended |
Rabies Vaccine
Given between 14 and 16 weeks of age, this vaccine is legally required in many places. It protects against rabies, a deadly disease that can affect both animals and people.
DHPP Booster
This is a repeat dose of the core puppy vaccines: Distemper, Hepatitis (Adenovirus), Parainfluenza, and Parvovirus. It helps strengthen your dog’s immunity as their body becomes more mature.
Optional Vaccines Based on Lifestyle
Some dogs, giant breeds or those who spend a lot of time outdoors may need extra vaccines:
- Leptospirosis – for dogs around water or in certain regions.
- Lyme Disease – for dogs exposed to ticks.
- Bordetella (Kennel Cough) – for dogs that go to daycare, boarding, or play with other dogs.
- Canine Influenza – for dogs in crowded or high-risk areas.
After these shots, your dog will need a follow-up booster at around 12 months old. After that, most vaccines are repeated every 1 to 3 years, depending on the type and your vet’s advice.
Adult Dog Vaccinations (1–7 Years)
Once dogs enter adulthood, to maintain their protection against diseases, you have to give about consistency and prevention. From age 1 through 7, regular vet visits and timely boosters help keep your dog healthy and up to date on necessary vaccines.
Routine Annual Check-Ups
Adult dogs should see a veterinarian at least once a year. These visits allow your vet to check your dog’s overall health, recommend boosters, and assess lifestyle-based risks for certain diseases.
Core Vaccines and Booster Timing:
- DHPP (Distemper, Hepatitis, Parvovirus, Parainfluenza):
After the 1-year booster, this combination vaccine is typically repeated every 3 years. - Rabies:
Also required every 3 years after the initial dose and 1-year booster, depending on local laws. - Leptospirosis:
Needs to be given annually, especially in regions or activities with higher exposure to wildlife or standing water.
| Vaccine | Booster Frequency | When It’s Needed |
| DHPP | Every 3 years | Routine core protection |
| Rabies | Every 3 years | Required by law in most areas |
| Leptospirosis | Annually | High-risk environments |
| Bordetella | Yearly / Every 6 months | Kennels, daycare, social dogs |
| Lyme Disease | Annually | Dogs exposed to ticks |
| Canine Influenza | Annually | Frequent exposure to other dogs |
