How often should you worm a dog in Australia? Age, risk and label schedules

"How often should I worm my dog?" is one of the most common questions we get — and the honest answer is: it depends. It depends on the type of worm, your dog's age and lifestyle, and the specific product you're using. There isn't one universal schedule that fits every dog, so here's how to work out yours. (For the bigger picture, start with our practical guide to fleas, ticks and worms.)

The short answer

Different worms need different products and different timing. Gastrointestinal worms and heartworm are separate jobs, and hydatid-tapeworm cover has to be confirmed on the label — and the frequency for each comes down to the individual product's label and your vet's advice, not a single rule of thumb.

Puppies vs adult dogs

Puppies generally require more frequent worming during their early months. Follow the product's age and weight directions and ask your veterinarian to set the puppy's schedule.

Gastrointestinal worms

An "all-wormer" targets the main gastrointestinal worms — roundworm, tapeworm, hookworm and whipworm. How often you give it as an adult varies by product and by your dog's risk (a dog that scavenges, hunts or mixes with lots of other dogs is more exposed than a homebody).

  • Always follow the dosing frequency on the label of the product you're actually using — that's the schedule that's been approved for it.

Heartworm is a separate thing

The term "all-wormer" does not guarantee heartworm cover. Some combination products include heartworm prevention; check the specific label. Heartworm is spread by mosquitoes and prevented with its own dedicated product, on its own schedule — monthly for many products, though some are longer-acting or given by your vet. Some approved heartworm-product labels recommend veterinary consultation or testing before commencement. Follow the specific label and ask your veterinarian before starting.

Hydatid tapeworm — one to confirm

Common tapeworm is usually part of an all-wormer's cover, but hydatid tapeworm is the one to confirm. It matters most for dogs in rural or farming areas, or dogs fed raw offal, and isn't covered by every all-wormer. If that's your dog's world, check the label, or ask your vet about a dedicated treatment.

How to set your dog's schedule

  • Read the specific label. The dosing frequency approved for that product (its APVMA-approved label) is the one to follow — don't borrow a schedule from a different product.
  • Weigh your dog. Doses are based on weight, and dogs change — a guess can under- or over-dose.
  • Set reminders. Calendar reminders help prevent missed treatments.
  • Ask your vet. Especially for puppies, for heartworm, and if you're unsure how to combine products safely.

Get those four right and worming stops being a guessing game — it's just a routine that suits your dog, on the schedule the label and your vet have set.

At Tidbit: our Flea & Worm Care range includes all-wormers such as Endogard Allwormer and Drontal Allwormer for Dogs, plus combination options such as Advocate, whose coverage must be checked on its label. Check each label for what it covers and how often to give it.
