At MountainView Veterinary Hospital in Denville, New Jersey, we believe preventive care is the cornerstone of lifelong wellness—and vaccinations are one of the most powerful tools we have to protect pets at every age. Whether you’re caring for a playful puppy, a curious kitten, or a senior companion, timely vaccination ensures your pet stays protected from a wide range of contagious (and often deadly) diseases.
This guide covers the core and optional vaccines for dogs and cats, outlines vaccination needs by life stage, and highlights why personalized vaccine schedules matter.

Why Vaccines Matter for Dogs and Cats
Vaccines train your pet’s immune system to recognize and combat disease-causing pathogens. By mimicking exposure to viruses or bacteria—without causing illness—vaccines help pets build strong defenses that can prevent severe disease or reduce symptoms.

Vaccination by Life Stage
Every pet has unique needs, but their life stage plays a major role in shaping their vaccination plan.
Puppies and Kittens
Young pets are especially vulnerable due to immature immune systems. Starting vaccines at 6–8 weeks of age with boosters every 3–4 weeks until 16 weeks old is critical.

Adults
After completing their initial vaccine series, adult pets need regular boosters to maintain immunity—typically every 1–3 years depending on lifestyle, vaccine type, and local regulations.
Seniors
Senior pets may require fewer vaccines but still benefit from protection, especially if their immune system weakens or if they remain active in the community.
