There is no single universal puppy calendar. AAHA's canine vaccination guidance separates core vaccines, which protect against broadly important diseases, from noncore vaccines chosen around geography, exposure, and lifestyle. Your veterinarian should set the schedule after reviewing age, health, maternal antibodies, travel, boarding, and local risk.
Understand the puppy series
Many puppies receive a series of core combination vaccines at intervals of roughly two to four weeks, with the final puppy dose given at or after 16 weeks of age according to the veterinarian's plan. The timing matters because maternal antibodies can interfere with early responses. Do not skip a visit because a puppy looks healthy.
Separate core from lifestyle decisions
Rabies is regulated by local law, while other core and noncore choices depend on the dog's risk. A puppy who hikes, boards, visits daycare, travels, or lives near wildlife may need a different plan from a homebody. Bring a list of destinations and regular activities to the appointment.
Keep an accurate record
Save the product names, dates, lot information when supplied, and next-due reminders. A clear record helps a new clinic avoid unnecessary repeats and makes boarding or travel paperwork easier. Ask what protection is expected after each dose and whether a booster or titer discussion is appropriate later.
Watch after vaccination
Mild tiredness or soreness can occur, but call the clinic for concerning or worsening signs. Facial swelling, trouble breathing, collapse, repeated vomiting, or severe weakness is urgent. Keep the puppy calm, follow the discharge instructions, and never change a vaccine plan based only on an online chart.
The bottom line
Use this guide as a practical starting point, then adjust for the individual animal, life stage, health history, and advice from a qualified veterinarian when health or appetite changes are involved.
