Simparica Trio is a monthly chew for small dogs (5.1–10kg) that combines flea, tick, heartworm, and intestinal worm protection in a single liver-flavoured tablet. One chew covers the full spectrum — no separate treatments needed.

The three active ingredients are sarolaner (fleas and ticks), moxidectin (heartworm), and pyrantel (intestinal worms including roundworm and hookworm). It kills fleas before they can lay eggs, covers paralysis ticks, and provides heartworm prevention in the same monthly dose. The palatable chew formulation means most dogs take it without any fuss.

Owners choose Simparica Trio when they want complete parasite coverage without juggling multiple products. A single monthly chew replaces what would otherwise be two or three separate treatments — straightforward to remember, straightforward to administer.
