Simparica TRIO is a monthly chewable that combines flea, tick, heartworm and intestinal worm protection in one liver-flavored tablet for dogs. It kills fleas before they lay eggs, controls paralysis and brown dog ticks for up to 35 days, and treats hookworms and roundworms. It also helps control flea allergy dermatitis. It is a prescription product, so a current heartworm test and a vet's authorization are needed. Compared with separate flea, tick and heartworm products, it replaces several monthly doses with one chew, which is its main advantage.
