Dog vaccinations are critical to ensuring your four-legged friend stays healthy from puppyhood into their senior years. Vaccines are the safest and most cost-effective way to protect your dog from many infectious preventable diseases.
The science behind canine vaccinations has progressed significantly over the past decade, enhancing both their safety and efficacy against existing and emerging pathogens. Here’s why vaccinating a dog is important.
Dog vaccinations are split into two general categories: core vaccines and noncore vaccines.
Core vaccines are required for all dogs and puppies. Core vaccines include:
Noncore vaccines (also called lifestyle vaccines) are considered optional and given based on factors such as your pet’s lifestyle and where you live. Several noncore vaccines protect against highly contagious or potentially life-threatening diseases.
To determine which lifestyle vaccines are appropriate for your dog, your vet will look at a variety of factors, including:
Noncore vaccines include:
For puppy vaccines to provide necessary protection, they’re given every two to four weeks until a puppy is at least 16 weeks old. Some dogs in high-risk areas may benefit from receiving the last vaccines around 18–20 weeks old.
Here’s an example of what a typical puppy shot schedule looks like:
Age
Core Vaccines
Noncore Vaccines
Parainfluenza (often included in DAP combo vaccine)
DAP (vets prefer giving final DAP vaccine at 16 weeks or later)
Rabies vaccine (may be
given earlier if
required by law)
*DAP (Distemper, Adenovirus/Hepatitis, Parvovirus. Sometimes also referred to as DHP or DHPP if parainfluenza is included.)
Ultimately, it’s important to consult with your veterinarian to identify the appropriate schedule for puppy vaccines for your specific pet.
Adult dogs need their core vaccines (DAP and rabies vaccines) in addition to any noncore vaccines decided upon between you and your veterinarian. A dog vaccination schedule for an adult dog may look like this:
Frequency
Core Vaccines
Noncore Vaccines
Annual vaccines for
Rabies (initial vaccine)
Bordetella (sometimes given
Dog vaccines given
Rabies (after initial vaccine,
given every 3 years)
No 3-year noncore vaccines are available at this time.
Ultimately, your veterinarian will determine how long a vaccine will work for your pet.
If your dog is overdue or if it’s their first time getting a vaccine, your vet may recommend a booster vaccine or an annual schedule so your pet is fully protected.
Keeping up with your dog vaccinations is the best way to protect your pup from many different illnesses, including:
Rabies is a virus that causes neurologic disease that is fatal for domestic pets, wildlife, and people. It’s most notably transmitted through a bite from an infected animal. If your dog has rabies, it can be transmitted to you or other people through bite wounds.
The rabies vaccine is required by law in the U.S. And despite the excellent vaccination system we have, there are still animals and people that come down with rabies every year.
Due to the fatality and zoonosis (meaning it can be transmitted from animals to people) associated with rabies, there are legal ramifications if your pet is not current on their rabies vaccine. Therefore, it is very important to keep your pet up to date.
It’s important to consult with your veterinarian to identify the appropriate schedule for puppy vaccines for your specific pet.
If an unvaccinated dog or a pet that’s past due for their rabies vaccine is exposed to a potentially rabid animal or accidentally bites someone, it may result in health concerns, the need to quarantine your pet, or humane euthanasia in certain circumstances.
The DAP vaccine protects against a combination of diseases that can spread quickly among dogs and have serious implications for canines, including severe illness and death.
Oftentimes, the noncore parainfluenza virus is also combined in this vaccine, changing the vaccine’s name to DAPP or DHPP.
Bordetella and canine parainfluenza virus are two agents associated with a highly contagious cough commonly known as kennel cough, or canine infectious respiratory disease complex (CIRDC).
Diseases from these agents typically resolve on their own but sometimes can lead to pneumonia or more severe respiratory disease. Because kennel cough is so contagious, boarding and doggy day care facilities across the U.S. require your pet to have this vaccine.
Parainfluenza may or may not be included in a combination vaccine with Bordetella or the DAP.
Canine influenza in the U.S. is caused by two identified strains of the virus: H3N2 and H3N8. It is highly contagious and causes cough, nasal discharge, and low-grade fever in dogs.
Outbreaks in the U.S. draw a lot of attention, as influenza viruses can give rise to new flu strains that have the potential to affect other species and possibly cause death.
Typically, the canine influenza vaccines are recommended for dogs that go to day care, boarding, the groomer, or any place where they will be among other dogs. Discuss with your vet if this vaccine is recommended for your pet.
Leptospirosis is a bacterial disease that can cause severe kidney or liver failure in both dogs and people. It’s transmitted via the urine of infected animals and is found in both rural and urban settings.
This vaccine is considered core in geographic locations where leptospirosis occurs, but it’s not considered universally a core vaccine. Dogs can be exposed to this illness by licking or coming in contact with a contaminated puddle or body of water where an infected animal has urinated.
Though traditionally, the leptospirosis vaccine was recommended to dogs in rural areas with outdoorsy lifestyles, leptospirosis has now been found to occur in suburban and urban settings, too. The city of Boston experienced an outbreak in 2018 likely due to urine of infected city rats.
Leptospirosis can be transmitted to people as well. Talk to your vet about whether they recommend this vaccine for your pet. The vaccine covers four of the most common serovars of leptospirosis, and the initial vaccine must be boostered two to four weeks later, and then annually thereafter.
Lyme disease is a tick-borne disease caused by the Borrelia burgdorferi bacteria that can cause fever, lethargy, decreased appetite, shifting leg lameness, and kidney failure in severe cases.
Lyme disease is endemic in various areas around the country (such as the northeast, northern Midwest, and Pacific coast), and the vaccine is recommended in these areas and for dogs traveling to places with high rates of the disease. Discuss with your vet if this vaccine is recommended for your pet.
Like leptospirosis, the vaccine is initially given as two injections spaced three to four weeks apart, and then yearly after that.
It’s important to discuss your dog’s lifestyle with your veterinarian so that they can make appropriate recommendations for which vaccines are necessary to protect your dog.
Apart from the necessary core vaccines, there is no one-size-fits-all protocol for vaccinating your dog. Working together with your veterinarian is the best approach to developing the right dog vaccine schedule for your beloved pet.
Vaccines are an essential part of dog and puppy care, and it is important to budget appropriately for them especially when getting a new puppy. Puppies typically get several different vaccines, often with boosters. But once they have been fully vaccinated will transition to an adult vaccine schedule of annually or even every three years for some vaccines. So, while getting a puppy started on vaccines may be an investment, this financial obligation will decrease during adulthood.
Vaccine costs may vary depending on where you live. Typically, the basic DHPP vaccine can cost about $25 per shot, while the rabies vaccine may be around $15–20. Other non-core vaccine prices can vary, but are generally less than $100 per shot.
To help offset the cost of vaccines, many local animal shelters or humane societies will have low-cost or even free vaccine clinics. Your veterinarian may be able to help identify these local options. Additionally, pet insurance may be a good way to help offset these costs. Many insurance carriers will have wellness or preventative care plans to cover some (or all!) of the core and non-core vaccines.
Dogs can have adverse reactions to canine vaccinations, medications, and even natural vitamins and supplements. These incidents are rare, but because they do occur, it’s important to monitor your pet after their vaccine appointment.
It’s common for dog vaccines to cause mild reactions, including discomfort or swelling at the injection site. Dogs may also develop a mild fever or have decreased energy and appetite for the day. But if any of these signs persist for longer than 24 hours, contact your veterinarian.
More serious side effects can occur within minutes to hours of the vaccination. Seek veterinary care immediately if your pet shows any of the following symptoms:
These reactions are much less common but can be life-threatening. Before your veterinarian administers any animal vaccines, alert them if your pet has had a reaction in the past.
