Rabies is a deadly viral disease that affects the nervous system and is nearly always fatal once symptoms appear. Fortunately, it’s also 100% preventable. Vaccinating your dog is the most effective way to protect them—and your community—from this threat. But how often do dogs need rabies shots?
Understanding the Rabies Vaccine Schedule
Most puppies receive their first rabies vaccine between 12 and 16 weeks of age. This initial dose is vital for building immunity. A rabies booster is then required one year later to reinforce your dog’s protection. After that, the recommended rabies vaccination schedule depends on local regulations, the type of vaccine used, and your dog’s lifestyle and health.
At Hershey Veterinary Hospital, we recommend an annual rabies vaccine for most dogs. However, we also offer the 3-year rabies vaccine upon request, as permitted by Pennsylvania state law.
One-Year vs. Three-Year Rabies Vaccines
Both 1-year and 3-year rabies vaccines contain similar ingredients—the main difference lies in how they’ve been tested and labeled. Regardless of the type of vaccine, it is required by law that your dog be up to date on their rabies shots. Pennsylvania’s rabies vaccine schedule for dogs mandates that all dogs be vaccinated by 3 months of age, with regular boosters thereafter.
Your veterinarian is your best resource for understanding what’s legally required and what’s best for your pet. If your dog frequently boards, visits dog parks, or travels across state lines, staying on top of rabies booster vaccinations becomes even more essential.
Why Dogs Need Booster Vaccinations
Rabies vaccinations stimulate your dog’s immune system to create antibodies that fight off the virus if they are ever exposed. But over time, immunity can fade. Booster vaccinations reintroduce the immune response, ensuring your dog stays protected.
Failing to vaccinate your dog as scheduled can carry serious consequences. If your dog bites someone or is bitten by an infected animal, they could be quarantined—or worse, euthanized—if their rabies vaccine is not current.
What to Expect After a Rabies Shot
Rabies vaccines are safe, but some dogs may experience mild side effects, such as:
- Swelling at the injection site
- Low energy or mild fever
- Temporary loss of appetite
In rare cases, dogs may have an allergic reaction such as vomiting, facial swelling, or difficulty breathing. These side effects usually appear within a few hours of vaccination. If you notice any of these signs, contact us immediately.
Local Laws and Rabies Vaccination in Pennsylvania
In Pennsylvania, rabies vaccination is required by law for all dogs and cats over 3 months of age. Proof of vaccination is needed for licensing, boarding, grooming, and travel. Compliance not only helps protect your dog but also shields you from legal liability in case of a bite or exposure incident.
At Hershey Veterinary Hospital, we maintain accurate records and provide official documentation for every rabies shot we administer. This ensures your dog is protected, both medically and legally.
