Adult dogs are usually wormed every 3 months, but some dogs need monthly treatment depending on lifestyle and risk; puppies are wormed much more often in the first months of life. Always confirm the exact schedule and product with a vet, because local parasites and your dog’s health can change what is safest.

Basic schedule

  • Adult low‑risk dogs (mostly indoors, don’t scavenge, no young children or vulnerable people at home): worm about every 3 months.
  • Adult higher‑risk dogs (eat things outside, hunt/scavenge, frequent dog parks, live with children, elderly or immunocompromised people): monthly worming is often recommended.
  • Use a broad‑spectrum product that covers roundworms and tapeworms, and follow the weight‑based dose on the pack or from your vet.

Puppies

  • Puppies typically start deworming at 2 weeks of age and repeat every 2–3 weeks until 12 weeks, because they can pick up worms from mum and the environment very easily.
  • After 12 weeks, many guidelines move them to monthly worming until about 6 months old, then to the adult schedule if healthy.

When to worm more often

  • Dogs that eat raw meat or carcasses, have fleas, or regularly visit high‑dog‑traffic areas may need monthly treatment to reduce both their risk and your family’s exposure.
  • Homes with pregnant women, children, elderly, or immunosuppressed people are often advised to keep dogs on the more frequent schedule.

Signs and vet checks

  • Weight loss, pot‑belly, dull coat, vomiting, diarrhoea, or visible worms in stool can all suggest a problem, but many infected dogs show no signs at all.
  • Vets can tailor a personal plan based on your dog’s age, lifestyle, country, and any other parasite meds (like flea/tick or heartworm preventives) already in use.
