Core Vaccines Timeline
Core vaccines are recommended for all dogs. Puppies typically start their first round between six and eight weeks of age, with boosters every two to four weeks until around 16 weeks.
Common core vaccines include DAPP (distemper, adenovirus, parvovirus, parainfluenza), leptospirosis, and rabies. Rabies vaccination is legally required for dogs in Iowa and is usually given at 12–16 weeks. Your veterinarian will provide a schedule tailored to your puppy's age and health.
Non-Core Vaccines
Non-core vaccines are recommended based on lifestyle and risk. Bordetella (kennel cough) may be advised if your puppy will board, attend daycare, or visit dog parks. Canine influenza vaccine may be recommended for dogs exposed to other dogs. Lyme disease vaccine may be considered in areas where ticks are common.
Your veterinarian will discuss which non-core vaccines make sense for your puppy based on where you live and how you plan to care for them.
How to Keep Puppies on Track
Bring your puppy's vaccination records to each visit so your veterinarian can confirm which vaccines are due. Schedule wellness exams at the recommended intervals to stay on schedule and catch any health concerns early.
If you miss a booster, your veterinarian can help you get back on track. Delays can leave your puppy vulnerable, so it's best to resume the schedule as soon as possible.
