How Often Should Dogs Get Vaccinated in Tennessee?

If you’re a dog owner in Ooltewah, TN, you’ve probably wondered: how often does my dog really need vaccines? The answer depends on your dog’s age, lifestyle, and risk factors—but staying on schedule is one of the most important ways to protect your pet’s health.

Be aware that, despite headlines to the contrary, vaccination is widely regarded as one of the greatest public health achievements in history. On the human side, the WHO estimates that routine immunization has saved more than 154 million lives over the last 50 years alone, and vaccines prevent approximately 4–5 million deaths every year worldwide and for animals, it is EVEN MORE IMPORTANT since pets can eat things that are not ideal, can drink out of puddles, and cannot have basic hygiene, like handwashing.

At Applebrook Animal Hospital, we help pet owners in Ooltewah, Apison, and Collegedale create personalized vaccination plans that keep dogs protected without over-vaccinating.

Core Vaccines: Every Dog Needs These

Core vaccines are recommended for all dogs, regardless of lifestyle.

These include:

  • Rabies
  • Distemper
  • Parvovirus
  • Adenovirus (hepatitis)
  • Some experts feel that Leptospirosis should be considered core in our region, so this vaccine is included in our wellness pacakges at no additional charge.

Typical Schedule:

  • Puppies: Every 3–4 weeks starting at 6–8 weeks old until about 16 weeks
  • Adults: Booster at 1 year, then every 1–3 years depending on the vaccine

Rabies vaccines are required by law in Tennessee, so keeping this current is essential.

Non-Core Vaccines: Based on Lifestyle

Not every dog needs every vaccine. We recommend these based on your dog’s exposure risk.

Common non-core vaccines:

  • Bordetella (kennel cough)
  • **Leptospirosis (see above)
  • Lyme disease
  • Canine influenza

Dogs who may need these:

  • Dogs who board or go to daycare
  • Dogs who hike or spend time outdoors
  • Dogs who visit dog parks or groomers frequently

In East Tennessee, we often recommend leptospirosis vaccination due to wildlife and water exposure risks.

How Often Do These Vaccines Need Boosters?

Here’s a simple breakdown:

  • Rabies: Every 1–3 years (legally required)
  • Distemper/Parvo combo: Every 1–3 years
  • Bordetella: Every 6–12 months
  • Leptospirosis: Annually

Your veterinarian will adjust timing based on your dog’s health and lifestyle.

Why Regular Vaccination Matters

Vaccines protect against serious, potentially fatal diseases that are still present in Tennessee. Parvovirus, for example, can survive in the environment and spread easily, especially in areas with high dog traffic.

Staying up to date also helps:

  • Prevent costly emergency care
  • Protect other pets in the community
  • Meet boarding, grooming, and travel requirements

Are Vaccines Safe?

Vaccines are very safe for most dogs. Mild side effects like soreness or fatigue can happen, but serious reactions are rare.

If your dog has had a vaccine reaction in the past, your veterinarian can adjust the plan to keep them safe.

The Bottom Line

Most adult dogs in Tennessee need vaccines every 1 to 3 years, with some lifestyle vaccines given annually or more often. The best approach is not a one-size-fits-all schedule—but a plan tailored specifically to your pet.
