Why puppies need repeat visits
Protection passed from the mother can interfere with early vaccinations and fades at different times in different puppies. That is why a course is needed. WSAVA guidance recommends starting core puppy vaccines at around six to eight weeks and repeating every two to four weeks until at least sixteen weeks. Your vet must adapt this to the vaccine used, health and exposure risk; some puppies need a longer course.
Ask what each vaccine protects against
Core protection includes canine distemper, adenovirus and parvovirus. Discuss rabies protection and other vaccines relevant to life in Sri Lanka with your vet. The timing and repeat doses differ between products and diseases, so do not treat the core puppy schedule as a rabies schedule. Ask for a written plan, including later boosters.
Bring the record and mention illness
Bring the original card or clear photographs, previous treatment details and any concerns about eating, vomiting or diarrhoea. If a date was missed or the history is unknown, let your vet decide how to catch up. Do not guess the next dose or assume the whole course must restart.
Balance protection with safe experiences
Ask how to introduce your puppy safely to people, sounds and suitable vaccinated dogs while protection develops. Avoid high-risk places and contact with sick or unknown dogs. After a vaccination, ask which mild effects to expect and when to call. Facial swelling, breathing difficulty or collapse needs immediate veterinary help.
