You should usually worm a puppy every 2 weeks at first, then every month, then move to an adult schedule under your vet’s guidance.

Quick Scoop

  • From about 2–3 weeks of age, most vets recommend worming puppies every 2 weeks until around 12 weeks old.
  • After that, many guidelines say to worm once a month until your puppy is 6 months old.
  • Once they reach 6 months, they usually go onto an adult schedule (often every 3 months, or monthly for higher‑risk dogs, depending on lifestyle and product).
  • Dose is based on weight , and you must use a wormer that is safe for young puppies and follow the product’s age/weight limits.
  • A vet or reputable breeder should show you what worming has already been done before you bring your puppy home and help you set up a schedule.

Simple example schedule (typical, but always check with your vet)

  • 2, 4, 6, 8, 10, 12 weeks: worm every 2 weeks
  • 3–6 months: worm every month
  • After 6 months: move to adult routine (often every 3 months, or monthly if high risk or as advised by your vet/product instructions)

Extra tips

  • Keep a worming calendar or phone reminders so you don’t miss doses.
  • Choose a product that covers the main intestinal worms in your area (roundworm, hookworm, tapeworm, etc.), as advised by your vet.
  • If your puppy seems unwell (vomiting, diarrhea, pot‑belly, weight loss, or worms in poop), speak to a vet promptly rather than just repeating a dose.

Always confirm the exact schedule and product with your own vet, because recommendations can vary slightly by country, parasite risk, and the specific wormer you use.
