As a responsible dog owner, keeping your pet healthy, dog vaccinations is a top priority. One of the most crucial steps in ensuring the well-being of your furry friend is getting them vaccinated against various diseases. This comprehensive guide will provide a detailed overview of everything you need to know about dog vaccinations – from the different types of vaccines to the recommended vaccination schedules, potential side effects, and more.
What Are Dog Vaccines and Why Are They Important?
Dog vaccines are specially designed to help stimulate the immune system of your furry friend and protect them from infectious diseases. Vaccines contain antigens that mimic disease-causing organisms in your dog’s body, triggering an immune response without actually causing the disease. Once the immune system recognizes these antigens, it will be better equipped to fight off the actual disease if your dog ever comes in contact with it.
Vaccinations are critical to keeping your dog healthy because they can protect them from a wide range of serious and potentially life-threatening illnesses. Even if your dog is healthy and seems to be free of any symptoms, they can still be at risk of contracting certain diseases. Therefore, keeping your dog up-to-date on their vaccinations is crucial for their overall health and well-being.
Core Dog Vaccinations
Core dog vaccinations are those that are considered essential for all canines, regardless of their breed, age, or lifestyle. These vaccines protect your dog from highly contagious and potentially deadly diseases that are easily preventable. The American Animal Hospital Association (AAHA) considers the following vaccines to be core:
Rabies
Rabies is a viral disease that affects the central nervous system and can be transmitted through the bite of an infected animal. It is a fatal disease that can affect both humans and animals, making it essential for all dogs to be vaccinated against rabies. Most states require dogs to be vaccinated against rabies by law.
Canine Distemper
Canine distemper is a highly contagious viral disease that can affect dogs of all ages. It can cause a wide range of symptoms, including fever, coughing, vomiting, diarrhea, and seizures, and can be fatal in severe cases. Vaccination against canine distemper is an essential part of any dog‘s vaccination schedule.
Parvovirus
Parvovirus is a highly contagious virus that can affect dogs of all ages, but is most common in puppies. It can cause severe vomiting, diarrhea, and dehydration, and can be fatal in severe cases. Vaccination against parvovirus is an essential part of any dog’s vaccination schedule.
Adenovirus
Adenovirus is a virus that can cause respiratory and liver infections in dogs. It can lead to severe illness and even death in some cases. Vaccination against adenovirus is another critical part of any dog’s vaccination schedule.
Non-Core Dog Vaccinations

Non-core dog vaccinations are those that are recommended based on your dog’s breed, age, lifestyle, and other factors. These vaccines are not necessary for all dogs, but they can provide additional protection against certain diseases. Some of the most common non-core dog vaccinations include:
Bordetella
Bordetella is a bacterial infection that can cause respiratory infections in dogs. It is highly contagious and can spread quickly through contact with infected dogs. Vaccination against Bordetella is recommended for dogs that are frequently exposed to other dogs, such as those that attend daycare, go to dog parks, or participate in dog shows.
Canine Influenza
Canine influenza is a highly contagious respiratory disease that can affect dogs of all ages. It can cause a range of symptoms, including coughing, sneezing, fever, and lethargy. Vaccination against canine influenza is recommended for dogs that are frequently exposed to other dogs, such as those that attend daycare, go to dog parks, or participate in dog shows.
Leptospirosis
Leptospirosis is a bacterial infection that can affect dogs and humans. It is transmitted through contact with contaminated water or soil and can cause a range of symptoms, including fever, vomiting, diarrhea, and kidney failure. Vaccination against leptospirosis is recommended for dogs that are frequently exposed to water or soil contaminated with the bacteria.
Lyme Disease
Lyme disease is a bacterial infection that is transmitted through tick bites. It can cause a wide range of symptoms, including fever, joint pain, and fatigue. Vaccination against Lyme disease is recommended for dogs that are frequently exposed to ticks, such as those that live in wooded areas or go hiking.
Puppy Vaccination Schedule

Puppies need to be vaccinated against various diseases to ensure they grow up healthy and strong. As a general rule, puppies should receive their first set of vaccinations between 6 and 8 weeks of age. The vaccination schedule for puppies typically includes:
6-8 Weeks
- Distemper, parvovirus
- Hepatitis
- Parainfluenza
- Bordetella
10-12 Weeks
- DHPP (distemper, hepatitis, parvovirus, parainfluenza)
- Leptospirosis
14-16 Weeks
- DHPP
- Leptospirosis
- Rabies
Adult Dog Vaccination Schedule
Once your dog has received their initial puppy vaccinations, they will need to receive booster shots to maintain their immunity. The vaccination schedule for adult dogs typically includes:
1 Year
- DHPP
- Leptospirosis
- Rabies
- Bordetella (if needed)
3 Years
- DHPP
- Leptospirosis
- Rabies
Potential Side Effects of Dog Vaccinations
While vaccinations are generally safe and well-tolerated by dogs, they can cause certain side effects in some cases. Some of the most common side effects of dog vaccinations include:
- Lethargy
- Mild fever
- Loss of appetite
- Swelling or pain at the injection site
- Vomiting or diarrhea
In rare cases, dogs can experience more severe reactions to vaccinations, including:
