Dog Vaccination & Preventive Care Schedule

Preventive care is the foundation of your dog's health. Vaccinations protect against deadly diseases, while parasite prevention and regular wellness exams catch problems early. This guide outlines recommended protocols for keeping your dog healthy.

Puppy Vaccination Schedule

Puppies receive maternal antibodies from their mother, but these fade over time. Vaccinations are given in a series to ensure protection as maternal immunity wanes.

Core Vaccines (Recommended for All Dogs)

AgeVaccines
6-8 weeksDHPP (Distemper, Hepatitis, Parvovirus, Parainfluenza) - 1st dose
10-12 weeksDHPP - 2nd dose; Bordetella (kennel cough) if boarding/daycare
14-16 weeksDHPP - 3rd dose; Rabies (required by law)
12-16 monthsDHPP booster; Rabies booster

Understanding Core Vaccines

Non-Core Vaccines (Based on Lifestyle/Risk)

Adult Dog Vaccination Schedule

After the puppy series, dogs need regular boosters to maintain immunity.

Recommended Schedule

Titer Testing

Titers measure antibody levels in blood. Some owners choose titers for core vaccines (except rabies) to avoid over-vaccination while ensuring protection. Discuss with your vet.

Parasite Prevention

Parasites cause disease, discomfort, and in some cases death. Year-round prevention is recommended in most climates.

Heartworm Prevention

Heartworm disease is transmitted by mosquitoes and is potentially fatal. Monthly prevention is essential.

Never Skip Heartworm Prevention

Heartworm treatment is expensive, risky, and hard on dogs. Prevention costs a fraction of treatment and is nearly 100% effective when given consistently. A single missed dose can result in infection.

Flea Prevention

Fleas cause itching, allergic reactions, tapeworms, and anemia in severe infestations.

Tick Prevention

Ticks transmit Lyme disease, Ehrlichiosis, Anaplasmosis, Rocky Mountain Spotted Fever, and other diseases.

Intestinal Parasite Prevention

Roundworms, hookworms, whipworms, and tapeworms are common intestinal parasites.

Wellness Exam Schedule

Regular veterinary exams catch problems before they become serious.

Recommended Frequency
