Simparica Trio is a monthly chewable parasite treatment for extra-large dogs weighing 40.1 to 60kg. The liver-flavoured chew combines three active ingredients to deliver all-in-one protection against fleas, ticks, heartworm, and intestinal worms — including roundworm, hookworm, and tapeworm — in a single monthly dose.

The three actives — sarolaner, moxidectin, and pyrantel — each target a different parasite class: sarolaner for fleas and ticks (including paralysis tick and brown dog tick), moxidectin for heartworm prevention, and pyrantel for intestinal worms. Simparica Trio also provides coverage against mites. Available in a 3-pack for three consecutive months of continuous protection.

For owners managing parasite prevention in a large dog, a single monthly chew that covers every major category simplifies the routine considerably. The liver flavour makes administration easier than most tablet-based treatments, with no need to conceal it in food.
