Adult dogs are typically wormed every 3 months, but many vets now recommend monthly worming for dogs with higher risk lifestyles or close contact with vulnerable people. Puppies need much more frequent worming, starting from 2–3 weeks of age and repeating every 2–3 weeks until around 12–16 weeks, then moving to an adult schedule.

Quick Scoop

  • Low‑risk adult dogs (mainly indoors, don’t scavenge, no young/elderly/immunocompromised people at home): usually every 3–6 months.
  • Average pet dogs (regular walks, off‑lead time, meet other dogs): often every 3 months, with some recent guidance suggesting many should be monthly depending on lifestyle.
  • High‑risk dogs (hunt/scavenge, eat poo, drink from puddles, live with children or elderly): often monthly worming is advised.
  • Puppies : start at about 2–3 weeks old and repeat every 2–3 weeks until 12–16 weeks, then follow a risk‑based adult schedule.

Typical Schedules

  • Many charities and vet‑linked sites suggest “at least four times a year” for adult dogs (every 3 months) as a baseline.
  • Newer risk‑based recommendations indicate that a large proportion of pet dogs may benefit from monthly worming, especially if they go off‑lead, scavenge, or live closely with families.
  • Worming products kill worms present at the time but do not protect long‑term, which is why regular repeat dosing is important.

When To Ask Your Vet

Because ideal frequency depends on:

  • Age (puppy vs adult vs senior)
  • Lifestyle (city flat vs rural, scavenging, hunting, raw food)
  • Household (children, pregnant women, elderly, immunocompromised people)

a vet can tailor a specific worming plan and product type for your dog. Always follow the product’s label and your vet’s advice on dose and interval.

TL;DR: For most pets, “every 3 months” is a common answer to how often should you worm a dog , but many everyday, outdoorsy family dogs are now put on a monthly schedule based on modern, risk‑based guidelines.
