Vaccinating is a vital part of preventive care for all pets, including your puppy! Routine vaccinations provide protection against several highly contagious and potentially life-threatening diseases, helping to safeguard your puppy’s long-term health and well-being. Some diseases like rabies and Lyme can even transfer from your dog to humans, so vaccinating protects you and your family as well. Dogs from birth to 1 year old are considered to be in their puppy years. (Think about humans between birth to 18 years old.) They have a lot of energy, curious minds, and plenty of cuteness to spare. To keep all that positive momentum going into their adult years, we must protect their good health today!
What Vaccines Are Required for My Puppy?*
Puppies need a series of core vaccinations that are recommended regardless of lifestyle or environment. These include DAPP (Distemper, Adenovirus, Parainfluenza, Parvovirus), Rabies, and Leptospirosis.
VACCINATION SCHEDULE FOR PUPPIES

DAPP VACCINE
This combination vaccine (multiple vaccines in one) protects your puppy from four common and contagious viral canine diseases:
Distemper Virus
Adenovirus (Hepatitis)
Parvovirus
Parainfluenza
Canine Distemper and Parvovirus are both serious, and often fatal diseases, that affect multiple organ systems and may require lengthy hospitalization, so protecting your pup is essential!
RABIES VACCINE
Rabies virus can be transmitted to dogs through a bite from an infected animal. Across the US, animals most often infected include raccoons, skunks, and bats—all creatures your puppy can come across outdoors. It’s important to note that this disease is fatal. Since it is one of the few life-threatening diseases that pets can transmit to humans, most states and/or county codes require all dogs to be vaccinated against rabies by law.
LEPTOSPIROSIS VACCINE
Leptospirosis (also known as “Lepto”) is a zoonotic, highly contagious bacterial infection. A zoonotic disease is an illness that can spread from animals to people through things like bites, scratches, or contact with their poop, saliva, or other body fluids. Leptospirosis is often transmitted to dogs when they have contact with, or drink from, warm bodies of water (e.g., lakes, streams, or puddles), walk where an infected animal has been (especially wildlife, rodents, and farm animals), or have direct contact with an infected animal.
If your puppy contracts leptospirosis, it can cause fever, lethargy, poor appetite, and muscle pain, progressing to vomiting, diarrhea, yellowing of skin/gums (jaundice), and signs of acute kidney injury (elevated creatinine/azotemia).
What Other Vaccines Does My Puppy Need?
In addition to the core vaccines required for puppies, there are various lifestyle-based vaccines like Bordetella, Lyme, and Influenza. These non-core vaccines are recommended based on your pet’s age, home location, daily activities, and frequency of contact with other animals.
Discuss these factors with your veterinarian to see if any of the lifestyle-dependent vaccines are suitable for your dog. Most of these vaccines need yearly boosters to maintain your dog’s protection.
Keep in mind that your pet’s risk of contracting one of these diseases can change at any point. Frequent reassessment with your dog’s veterinary care team is essential in helping them stay protected as their activities and environment shift throughout their life.
*Vaccine requirements and schedules can vary by state and by individual pet needs. Your veterinarian stays up to date on local regulations and medical guidelines and can recommend the right vaccines and timing for your pet.
