Vaccinations are one of the most important aspects of keeping your dog healthy. They protect against deadly diseases and help prevent the spread of infections among animals. Whether you have a new puppy or an adult dog, staying up to date on vaccinations is essential for their long-term well-being. In this guide, we’ll cover the core and non-core vaccinations that every dog should receive.
Core Vaccinations for Dogs
Core vaccines are essential for all dogs, regardless of breed, age, or lifestyle. These vaccines protect against life-threatening diseases that can spread easily among dogs.
1. Rabies Vaccine
-
Why it’s important: Rabies is a fatal viral disease that affects the nervous system of mammals, including humans. It spreads through bites from infected animals.
-
When to vaccinate: Puppies should receive their first rabies shot at around 12-16 weeks of age, with a booster given one year later. After that, rabies vaccines are required every one to three years, depending on local laws.
2. Canine Distemper Vaccine
-
Why it’s important: Canine distemper is a highly contagious and often fatal disease that affects a dog’s respiratory, digestive, and nervous systems. It spreads through airborne exposure and direct contact.
-
When to vaccinate: Puppies receive their first dose between 6-8 weeks, with booster shots every 3-4 weeks until they are 16 weeks old. Adult dogs need boosters every 1-3 years.
3. Canine Parvovirus Vaccine (Parvo)
-
Why it’s important: Parvovirus is a highly contagious virus that causes severe gastrointestinal issues, including vomiting, diarrhea, and dehydration. It is particularly dangerous for puppies.
-
When to vaccinate: Puppies get their first shot at 6-8 weeks, with additional doses every 3-4 weeks until 16 weeks of age. Adult dogs need a booster every 1-3 years.
4. Canine Adenovirus (Hepatitis) Vaccine
-
Why it’s important: Adenovirus causes infectious canine hepatitis, which affects the liver, kidneys, spleen, and lungs. It spreads through bodily fluids and contaminated objects.
-
When to vaccinate: The vaccine is usually given as part of the DHPP (Distemper, Hepatitis, Parvovirus, and Parainfluenza) combination shot. Puppies receive it at 6-8 weeks, with boosters until 16 weeks and then every 1-3 years for adults.

Non-Core Vaccinations for Dogs
Non-core vaccines are recommended based on a dog’s lifestyle, location, and risk factors. These vaccines protect against diseases that may not be as widespread but are still a concern in certain areas.
1. Bordetella (Kennel Cough) Vaccine
-
Why it’s important: Bordetella bronchiseptica is a bacteria that causes kennel cough, a highly contagious respiratory infection. It is commonly spread in kennels, dog parks, and boarding facilities.
-
When to vaccinate: This vaccine is recommended for dogs that socialize frequently. It can be given as an injection or nasal spray, starting at 8 weeks of age, with boosters every 6-12 months.
2. Leptospirosis Vaccine
-
Why it’s important: Leptospirosis is a bacterial infection that can affect the liver and kidneys. It spreads through contaminated water, soil, and urine from infected animals.
-
When to vaccinate: This vaccine is recommended for dogs in rural or high-risk areas. Puppies receive it at 12 weeks, with a booster 3-4 weeks later and annual revaccination.
3. Canine Influenza (Dog Flu) Vaccine
-
Why it’s important: Canine influenza is a respiratory disease that spreads quickly in dog shelters, kennels, and daycares. It can cause coughing, fever, and pneumonia.
-
When to vaccinate: Recommended for social dogs, the vaccine is given in two doses, 2-4 weeks apart, followed by annual boosters.
4. Lyme Disease Vaccine
-
Why it’s important: Lyme disease is transmitted by ticks and can lead to joint pain, fever, and kidney disease in dogs. It is most common in wooded and grassy areas.
-
When to vaccinate: This vaccine is recommended for dogs that spend a lot of time outdoors. It is given as two doses, 2-4 weeks apart, followed by annual boosters.
Puppy Vaccination Schedule
A proper vaccination schedule is crucial for puppies, as their immune systems are still developing. Below is a general timeline:
-
6-8 weeks: Distemper, Hepatitis, Parvovirus, Parainfluenza (DHPP)
-
10-12 weeks: DHPP booster, Bordetella (optional)
-
12-16 weeks: Rabies, DHPP booster, Leptospirosis (if needed)
-
Every 1-3 years: Booster shots for core vaccines and non-core vaccines as recommended
