Vaccinations are essential for keeping your dog healthy, protecting them from puppyhood through their senior years.
Vaccinations for dogs are essential for maintaining the health of your canine companion from their early stages through to their senior years. Vaccines represent the most secure and economical method to shield your dog from a variety of preventable infectious diseases.




The advancements in the science of canine vaccinations over the last decade have significantly improved their safety and effectiveness against both established and emerging pathogens. The importance of vaccinating dogs cannot be overstated.
What Are the Common Dog Vaccinations?
Dog vaccinations are categorized into two main types: core vaccines and lifestyle vaccines.
Core Vaccines
Core vaccines are mandatory for all dogs and puppies. The core vaccines include:
- Canine distemper/adenovirus-2 (hepatitis)/parvovirus/parainfluenza vaccine (administered as a single vaccine, commonly known as DA2PP, DHPP, or DAPP)
- Rabies virus vaccine
- Leptospira (Leptospirosis) vaccine (this can also be administered in conjunction with the DA2PP/DAPP vaccine, referred to as the DHLPP vaccine)
Lifestyle Vaccines
Lifestyle vaccines are optional and are administered based on specific factors such as your pet’s lifestyle and geographical location. Several lifestyle vaccines provide protection against highly contagious or potentially fatal diseases.
To ascertain which lifestyle vaccines are suitable for your dog, your veterinarian will evaluate various factors, including:
- Geographic location and the prevalence of diseases in those areas
- Whether your pet frequents doggy day care, dog parks, or boarding and grooming facilities
- Your pet’s lifestyle, including travel, hiking, or exposure to natural environments
- The overall health status of your pet
Lifestyle vaccines include:
- Bordetella bronchiseptica (kennel cough) vaccine
- Borrelia burgdorferi (Lyme) vaccine
- H3N2/H3N8 (canine influenza) vaccines
- Crotalus atrox (rattlesnake) vaccine
Puppy Vaccination Timeline
When should puppies receive their vaccinations?
To ensure adequate protection, puppies should receive vaccinations every two to four weeks until they reach a minimum age of 16 weeks. Certain breeds, as well as puppies residing in high-risk environments, may benefit from receiving their final vaccinations between 18 and 20 weeks of age.
Below is a sample vaccination schedule:
Common Dog Vaccination Schedule:
Age | Vaccine | Type | Dosage |
---|---|---|---|
6-8 Weeks | DHPP (Distemper, Hepatitis, Parvovirus, Parainfluenza) | Core Vaccine | 1st Dose |
Bordetella (Kennel Cough) | Non-Core Vaccine | 1st Dose (Optional) | |
10-12 Weeks | DHPP Booster | Core Vaccine | 2nd Dose |
Leptospirosis | Non-Core Vaccine | 1st Dose (Optional) | |
Bordetella (If not given at 6-8 weeks) | Non-Core Vaccine | 1st Dose | |
12-14 Weeks | DHPP Booster | Core Vaccine | 3rd Dose |
Rabies | Core Vaccine | Single Dose | |
Leptospirosis Booster | Non-Core Vaccine | 2nd Dose (if given earlier) | |
Annually | DHPP Booster | Core Vaccine | 1 Dose |
Rabies (as per local law) | Core Vaccine | 1 Dose | |
Bordetella, Leptospirosis, Canine Influenza | Non-Core Vaccines | 1 Dose (If required) |
Adult Dog Vaccine Schedule
Frequency | Core Vaccines | Lifestyle Vaccines |
---|---|---|
Annual Vaccines | Rabies (initial vaccine) | Lyme |
Leptospirosis | Canine Influenza | |
Bordetella (sometimes given every 6 months) | ||
Every Three Years | DAP (Distemper, Adenovirus, Parvovirus) | No three-year lifestyle vaccines available |
Rabies (after initial vaccine) |
Key Notes:
- Core Vaccines: Essential for all dogs to protect against life-threatening diseases.
- Lifestyle Vaccines: Optional and recommended based on your dog’s environment, activities, and risk factors.
- Always consult your veterinarian to tailor the vaccination schedule to your dog’s specific needs.
Additional Information:
- If your dog is overdue for vaccines or it’s their first time, your vet may recommend a booster shot or an annual schedule to ensure full protection.
- Vaccination schedules may vary depending on local laws, your dog’s health, and lifestyle.
What Illnesses Are Prevented by Dog Vaccinations?
Maintaining your dog’s vaccination schedule is essential for safeguarding your pet against a variety of diseases, including:
Rabies
Rabies is a viral infection that leads to severe neurological disorders, posing a fatal risk to domestic animals, wildlife, and humans. The virus is primarily spread through bites from infected creatures. If a dog contracts rabies, it can be transmitted to humans or other animals through bite injuries.
In the United States, the rabies vaccine for dogs is mandated by law. Despite the robust vaccination programs in place, rabies cases continue to be reported annually.
Given the lethal nature of rabies and its zoonotic potential (the ability to be transmitted from animals to humans), there are legal consequences for pet owners whose animals are not up to date on their rabies vaccinations. Thus, it is crucial to ensure that your pet’s vaccinations are current. If an unvaccinated dog or one that is overdue for its rabies vaccine comes into contact with a potentially rabid animal or bites someone, it could lead to serious health issues, the necessity for quarantine, or even humane euthanasia in certain situations.
The DAP vaccine protects
The DAP vaccine offers protection against a range of diseases that can rapidly transmit among dogs, posing significant health risks, including severe illness and mortality.
Canine distemper is a highly contagious and severe disease affecting unvaccinated dogs, leading to serious neurological symptoms, pneumonia, fever, encephalitis, and potentially death.
Adenovirus type 1, also referred to as infectious canine hepatitis, is a viral infection that can cause upper respiratory infections, fever, liver and kidney failure, as well as ocular complications.
Canine parvovirus is notably contagious and can result in severe symptoms such as vomiting, diarrhea, lethargy, dehydration, and in extreme cases, death.
Often, the lifestyle parainfluenza virus is included in this vaccine, resulting in the alternative names DAPP or DHPP.
Bordetella and canine parainfluenza virus are two pathogens linked to a highly contagious respiratory condition known as kennel cough, or canine infectious respiratory disease complex (CIRDC).
While infections caused by these agents generally resolve without intervention, they can occasionally progress to pneumonia or more serious respiratory illnesses. Due to the highly contagious nature of kennel cough, many boarding and dog daycare facilities across the United States mandate this vaccination for pets.
Parainfluenza may or may not be part of a combination vaccine that includes Bordetella or the DAP.
Canine Influenza, Leptospirosis, and Lyme Disease: What You Need to Know
