Simparica Trio is a monthly chewable parasite treatment for large dogs weighing between 40.1 and 60 kilograms. It combines three active ingredients in a single pork-flavoured chew to cover fleas, ticks, heartworm, and intestinal worms simultaneously. The 6-pack provides six months of continuous protection for dogs at the heavier end of the size range.

The three actives — sarolaner, moxidectin, and pyrantel — kill fleas within hours of dosing, target paralysis ticks and brown dog ticks, prevent heartworm disease, and treat roundworm, hookworm, and whipworm. Each chew is pork-flavoured, which most dogs accept readily. Monthly dosing means one chew handles everything — no separate spot-on or additional tablet required alongside it.

Owners who've previously juggled separate flea, tick, and worming products for large dogs often settle on Simparica Trio to consolidate the routine. Consistent monthly dosing matters more than any individual product feature in parasite control, and a single chew is easier to stay on top of.
