Why Vaccinating Your Pet Is Essential in Denver:

Keeping your pet protected starts with prevention—and in a busy city like Denver, vaccinations are one of the most important tools we have. From mandatory rabies laws to the heightened risk of disease spread in dog parks and urban wildlife encounters, pets here need consistent and thoughtful immunization to stay healthy.

At State of the Heart Vet, we believe vaccinations are not just routine—they’re part of a compassionate, personalized approach to lifelong care. Dr. Daughtry and our team tailor each pet’s vaccination schedule based on breed, age, lifestyle, and health history to make sure they get only what they truly need.

What Vaccines Are Common for Pets in Denver?

Core vs. Non-Core Vaccines

We divide pet vaccines into two categories:

  • Core Vaccines are essential for all pets:
    • Dogs: Rabies, distemper, parvovirus, adenovirus
    • Cats: Rabies, panleukopenia, calicivirus, herpesvirus
  • Non-Core Vaccines are recommended based on lifestyle:
    • Bordetella (kennel cough)
    • Parainfluenza (kennel cough)
    • Leptospirosis
    • Lyme disease
    • Feline leukemia (FeLV)

Local Considerations for Denver

Because Denver pets are often exposed to other animals in daycares, parks, or hiking trails—and may even encounter local wildlife like raccoons or coyotes—we often recommend certain non-core vaccines to support their immunity in a Colorado-specific context.

Are Yearly Pet Vaccinations Really Necessary?

Annual vs. Multi-Year Boosters

Some vaccines, like rabies, can be administered every 1 to 3 years depending on the product and state laws. Others, like bordetella or leptospirosis, may require annual boosters.

Annual wellness exams are a great opportunity to re-evaluate your pet’s vaccine schedule. Their risk factors can change over time—especially if you’ve moved, added a new pet to your home, or increased social exposure.

What Dr. Daughtry Recommends

We don’t believe in one-size-fits-all care. Dr. Daughtry will work closely with you to determine if titers (antibody tests) or extended vaccine intervals make sense for your pet. The goal is always to balance protection with safety.

What Happens If You’re Late on Puppy Shots?

Risks of Delayed Vaccination

Puppy and kitten vaccines are scheduled in a precise series for a reason: their immune systems are developing, and delays can leave them vulnerable. Missing or delaying shots can increase their risk of contracting parvovirus, distemper, or other serious illnesses.

What to Do if You Miss a Dose

If you’ve missed a visit or your schedule got off track, don’t worry. At State of the Heart Vet, we’ll review your pet’s history and safely restart or adjust their schedule so they can get back on track—without restarting from scratch unless absolutely necessary.

Understanding the Risks and Benefits of Vaccinations:

Benefits

Vaccines offer protection not just for your pet, but for your family and community. Here’s why they matter:

  • Prevent potentially deadly diseases
  • Reduce the spread of contagious illnesses
  • Lower your long-term medical costs
  • Meet legal requirements in Colorado (e.g., rabies)
  • Allow your pet to meet the requirements for air travel and international travel

Side Effects and What to Watch For

Vaccines are overwhelmingly safe, but mild side effects can occur, including:

  • Soreness or swelling at the injection site
  • Mild fever
  • Sleepiness or reduced appetite for a day

In rare cases, pets may experience allergic reactions. If you notice vomiting, diarrhea, facial swelling, profound lethargy, or difficulty breathing within the first 24 hours after a vaccine has been given, then call us immediately. We’re here to support you through any concerns.

When Should Puppies and Kittens Get Vaccinated?

Your pet’s first vet visit should ideally be around 6 to 8 weeks of age. From there, they’ll receive a series of vaccines every 2 to 4 weeks until they’re about 16 weeks old. A rabies shot is typically administered around 13-16 weeks, depending on state laws.

Early, consistent care ensures that your new companion grows into a healthy adult with lifelong immunity.

Adult Pets: How Often Should Boosters Be Given?

Booster timing depends on vaccine type and your pet’s health:

  • Rabies: Every 1 to 3 years (required by Colorado law)
  • Distemper, parvo combo: Typically every 1 to 3 years
  • Lifestyle vaccines: Annual or biannual, depending on exposure risk

We may recommend titer testing—especially for pets with medical sensitivities or senior pets—to determine whether immunity is still adequate before re-administering certain vaccines.
