Rabies is one of the most serious viral diseases that can affect both animals and humans. Because it’s nearly always fatal once symptoms appear, vaccination is critical—not just for your dog’s health, but for public safety as well. Many dog and new puppy owners wonder: How often do dogs need rabies shots? The answer can vary depending on your state laws, your veterinarian’s recommendations, and the type of vaccine your dog receives.
In this guide, we’ll break down everything pet owners should know about rabies vaccination schedules, why they’re so important, and what to expect when it’s time for your dog’s rabies shot, which is considered a core dog vaccine.
What Is Rabies and Why Is Vaccination Important?
Rabies is a deadly virus that attacks the nervous system and spreads through the bite or saliva of infected animals. In the United States, rabies most commonly spreads through wildlife such as raccoons, bats, skunks, and foxes. Once contracted, rabies has no cure. That’s why prevention through vaccination is absolutely necessary.
What Are the Symptoms of Rabies in a Dog?
The symptoms of rabies typically occur about three to seven weeks after the virus enters the dog’s body. There are different symptoms for each stage. However, there are some common signs that a dog may have rabies. Here are the symptoms:
-
Hiding
-
Vomiting
-
Exhaustion
-
Bite wounds
-
Lack of appetite
-
Difficulty breathing
-
Hypersalivation
-
Foaming at the mouth
-
Behavioral changes
-
Sensitivity to light
The early symptoms are often difficult to detect and may not impact a pet's lifestyle too much. The dog may also have a fever in addition to the above symptoms. If your dog is experiencing any of these symptoms, seek veterinary care right away.
Why Rabies Shots Matter in a Dog or Puppy's Life:
-
They protect your dog from a fatal disease.
-
They prevent you and your family from getting a potential exposure.
-
They protect other dogs from exposure.
-
They are legally required in most states and municipalities.
-
They help prevent the spread of rabies within communities.
How Often Do Dogs Need Rabies Shots?
The rabies vaccination schedule depends on two key factors: your dog’s age and the type of rabies shot or vaccine administered.
1. Puppy Rabies Vaccination
-
First rabies shot: A puppy typically receives their first rabies vaccination at 12 to 16 weeks of age.
-
This first dose is vital to establish immunity early in life.
2. First Booster Shot
-
After the initial puppy vaccine, dogs need a booster rabies shot one year later.
-
This ensures strong, long-lasting protection against the virus.
3. Adult Dog Rabies Vaccination
-
After the first booster, it is generally recommended that dogs receive rabies vaccines either every 1 year or every 3 years depending on the vaccine used and state regulations.
-
1-year: Provides protection for 12 months.
-
3-year: Provides protection for 36 months, but not all states allow it.
1-Year vs 3-Year Rabies Vaccinations: How Long Do Pet Rabies Shots Last?
While some rabies vaccinations are licensed for one year, others are labeled for three years, but some states require annual vaccinations regardless of labeling. Your veterinarian will know your state’s laws and keep your pet on the appropriate vaccination schedule.
Whether your pet only needs a rabies vaccination every three years or not, you should still schedule annual wellness visits for your furry friend. Regular wellness exams are the most important preventive measure that you can provide for your pet, and vaccinations are just one component of a wellness visit. Since pets don’t always show signs of early disease, annual or biannual exams are vital for keeping your pet in optimal health, regardless of how often vaccinations are administered.
It is important to note that: three-year rabies vaccinations are the same as one-year vaccinations. There is no additional volume or disease agent administered to trigger an immune response; the labeling is simply different for the vaccinations. Although your pet may receive a vaccination labeled for one year and is technically protected for three years, they are not legally protected for three years in the eyes of the state.
“The differences between one-year and three-year vaccines depend on the specific vaccines,” said Dr. Lori Teller, a clinical associate professor at the Texas A&M School of Veterinary Medicine & Biomedical Sciences. “Many of the adjuvanted vaccines — or vaccines with an added chemical to boost immune response and ensure protection — are similar, with the only difference being the label. The biggest factor that owners should consider is what the law is in their jurisdiction.”
How Much Does a Dog Rabies Vaccination Cost?
Fortunately, a rabies shot for dogs is easy to obtain, not too costly, and is deemed safe for your dog. Because rabies is a public health concern, the vaccine will be administered by a veterinarian after she or he has done a physical exam on your dog.
The cost of a veterinary exam usually runs from about $40 to $100, depending on the type of practice and your geographical area. The cost of a rabies vaccination for dogs typically ranges between $15 to $80 depending on your vet and where you live.
For cost-conscious pet parents who still want to protect their dog against infectious diseases, the price of vaccines can be reduced in several ways. There are many options available to get a low-cost rabies shots for dogs, including:
-
Low-cost vaccine clinic at a pet store or feed store
-
Low-cost vaccine clinic at a shelter
-
Mobile/pop-up vaccine clinics
To find one of these clinics, Google “low-cost vaccine clinics” for your area or ask at your local pet store.
You can also ask your veterinary office if they run vaccine "specials", like on September 28, also known as World Rabies Day. Other options include puppy packages that bundle and discount all puppy services (vaccines, de-worming, fecal exam, puppy exams, spay/neuter, microchip, etc.), or insurance/wellness plans that include vaccines.
Rabies Vaccination Requirements by Law
One of the most important things to know is that rabies vaccines aren't just about health—it’s the law in most areas. Each state (and sometimes county or city) has its own rabies vaccination requirements for dogs.
For example:
-
Some states mandate yearly rabies shots regardless of the vaccine used.
-
Other states accept the 3-year rabies vaccine and only require re-vaccination every 36 months.
-
Failure to vaccinate your dog can result in fines or legal consequences, and unvaccinated dogs may face quarantine if they bite someone.
Here in New York, rabies vaccination is legally required for all dogs, cats, and ferrets four months of age and older. The first vaccination for a puppy must be administered by a licensed veterinarian, followed by a booster dose within one year. Subsequent booster shots are required either annually or every three years, depending on the type of vaccine used. Failure to comply with these laws can result in fines, restrictions on pet ownership, or mandatory quarantine if exposed to rabies
👉 Always check your local laws and discuss with your veterinarian which rabies vaccination schedule applies to your dog.
High Risk Areas for Rabies
While the USA has successfully eliminated dog rabies as of 2007, thanks to vaccines and other measures, importation regulations are in place to prevent its reintroduction. High-risk areas for dog rabies are primarily outside the US, with many countries in Africa and Asia having significant issues with dog rabies control, according to the World Health Organization.
In the United States, the animals most commonly associated with rabies and it's infection are raccoons, bats, skunks, and foxes. While all mammals are theoretically susceptible to rabies, these four species are considered major wildlife reservoirs for the virus in North America, according to the Commonwealth of Pennsylvania. Bats are the most frequently reported rabid animal in the USA.
Signs of Side Effects After Rabies Vaccination
Rabies shots are generally safe, but like any medical treatment, mild side effects and adverse reactions can occur. Common side effects and risk factors include:
-
Mild swelling at the injection site
-
Fatigue or slight decrease in activity
-
Mild fever
-
Temporary loss of appetite
-
Mild vomiting
-
Infection
Rarely, dogs may experience more serious allergic reactions such as facial swelling, severe vomiting, or difficulty breathing. If you notice severe symptoms, it is extremely important that you contact your veterinarian immediately to keep your pup safe.
Why You Shouldn’t Skip Rabies Shots
Skipping rabies vaccinations puts your dog—and everyone around them—at risk. If your unvaccinated dog bites someone or is bitten by wildlife, the consequences can be severe. Depending on your state laws, an unvaccinated dog may be:
-
Quarantined for an extended period, or
-
Euthanized if they are suspected of rabies exposure.
Keeping your dog current on rabies shots protects them and you, and ensures you stay compliant with the law.
Can I Test My Pet’s Rabies Titers Instead of Vaccinating?
While there is titer testing for rabies available, antibody testing does not correlate with protection and only denotes prior vaccination. Titer testing provides information as to whether a pet has been exposed to a disease before, but not how well the individual puppy will react when threatened with the disease. Rabies titer testing is used for pets who are being exported to rabies-free portions of the world to determine that the pet has been recently vaccinated against rabies, not as evidence of protective immunity.
Although you can ask for titers for other diseases in lieu of vaccination, you cannot do that for rabies. Rabies is the only vaccine that is required by law in the United States, as it is a fatal disease. It is also a zoonotic disease, meaning it can be transmitted from animals to people. For the health of the general public and their pets, all pets must be appropriately vaccinated for rabies, according to state guidelines.
Vaccine requirements for each pet and geographic location are different. Please speak to your veterinarian about the best vaccination protocol for your specific pet, location, and lifestyle.

WHO IS PRIDE+GROOM?
PRIDE+GROOM was born because a group of New York City dog lovers wanted the same level of grooming products for their dogs that they themselves enjoyed. They looked (hard) but nothing was up to snuff. Or sniff. Like so many, we love our families and take pride in our homes, and we consider our pets to be integral parts of those entities. That said, we could not find an effective way to coif them that was on par with the way we tended to our children, our homes, or ourselves. These beloved pets are allowed on the furniture and in our beds, and yet even when fresh from the groomer, we knew they did not smell or feel as good as they could.
With the development of our coat-specific shampoos, conditioner and deodorizing spray, we think we found just the way to say thanks for being the best and the sweetest MVP of the house. Skin and coat health is very important to us.
PRIDE+GROOM is the first dog grooming brand launched under a beauty platform, with formulas made in a clean beauty and scent lab. We know beauty is not only skin deep. We did a ton of research to create the entire line. Each product is formulated with its own unique blend of essential oils sourced from around the world.
