The Simparica TRIO Flea, Tick & Worm Chewables for Medium Dogs 10.1–20 kg are specially formulated to provide fast-acting, monthly protection against fleas, ticks, worms and heartworm for medium dogs. Between the warm climate, our love for the outdoors and your dog’s innate ability to find the muddiest, smelliest spot to roll around in - effective, year-round parasite protection is a non-negotiable in Australia.


Simparica TRIO is a monthly chew that provides vet grade protection against the opportunistic, blood-thirsty freeloaders that prey upon our furry friends. TRIO delivers APVMA-approved, all-in-one protection against a whole gamut of these nasty, hitchhiking parasites like (deep breath) fleas, paralysis ticks, deadly heartworm, roundworm, hookworm, mites, mange and even mosquitoes.


It’s developed by the world’s leading animal health company, lasts up to 35 days and has a tasty liver flavour so you get peace of mind, a little leeway and they get their treatment disguised as a treat. Simparica TRIO. Vet grade protection for dogs, trusted by dog people across Australia and the world.


Features and benefits:

  • The only triple attack on heartworm: Prevents infection, kills juvenile heartworm and eliminates the mosquitoes that transmit it.
  • Fast-acting: Kills fleas within 4–8 hours and ticks within 24 hours.
  • No gaps, ever: Monthly protection that lasts up to 35 days for fleas & ticks.
  • Full worm cover: Treats and controls heartworm, roundworm and hookworm in one chew.
  • Handles the extras too: Treats ear mites, demodex mites, sarcoptic mange and flea allergy dermatitis.
  • Easy to give: Tasty, liver-flavoured chew that goes down a treat, with or without food.
  • Safe for sensitive breeds: Well tolerated in Collies and other avermectin-sensitive dogs.
  • Vet-grade: From Zoetis, trusted in animal health for 70+ years.

Directions of Use

    1. Choose the right dose. Select the Simparica TRIO pack that matches your dog's body weight - refer to the weight guide if unsure.

    2. Give monthly, with or without food. Most dogs take it like a treat. For fussier dogs, pair the chew with a preferred treat or place directly into their mouth.

    3. Repeat every month, year-round for continuous protection. Start at any time of year — there's no need to wait for tick season.

    4. Missed a dose? Give as soon as you remember and continue their regular monthly schedule.
