Vet Approved Vaccine Guide for Puppies, Adults & Seniors 2025 🏥🐶

By Dr. Duncan Houston BVSc

🏥 Introduction: Why Vaccines Matter at Every Age

Vaccinations are one of the most important tools in preventive veterinary medicine. Whether you’re raising a puppy, managing an adult dog’s boosters, or caring for a senior pup, vaccines protect against life-threatening illnesses. As a veterinarian, I help families understand which vaccines are essential, optional, and time-sensitive—so your dog stays safe throughout life. 🐾

This guide covers:

• ✅ Core and non-core vaccines for each life stage
• 📅 How vaccine timing and frequency change with age
• ✅ How to use Ask A Vet,

1. Puppy Vaccine Schedule (6 Weeks to 16 Weeks) 👶

• DHPP (Distemper, Hepatitis, Parainfluenza, Parvovirus): 3-4 doses starting at 6–8 weeks old, repeated every 3–4 weeks
• Bordetella: Optional; often required for puppy daycare or training classes
• Leptospirosis: Recommended based on region and exposure risk
• Canine Influenza: Optional in high-risk social environments
• Rabies: First dose typically at 12–16 weeks, by law in most areas

2. Adult Dog Vaccine Schedule (1 to 7 Years) 🐶

• DHPP Booster: Every 1–3 years based on vet recommendation
• Rabies: Boosters every 1–3 years depending on local laws
• Leptospirosis: Annual booster if applicable
• Bordetella & Canine Influenza: Annual or semi-annual for social dogs

Healthy adult dogs may tolerate vaccines well, but always monitor for side effects like fatigue or mild swelling at the injection site.

3. Senior Dog Vaccine Care (7+ Years) 🧓

• DHPP & Rabies: Continue as recommended unless medically exempt
• Lepto, Bordetella, Flu: Consider lifestyle and immune tolerance

Ask A Vet can assess whether any vaccines can be safely skipped based on health history or age-related risk.

4. When to Delay or Adjust Vaccines ⚠️

• 🤒 Dogs with fever or illness
• 🧍 Immunocompromised or allergic dogs
• 🤱 Pregnant or nursing dogs (vet-supervised only)

Use Ask A Vet to make vaccine decisions personalized and safe.
