Zoetis (ZTS -0.36%) announced on Thursday that its new all-in-one parasite protection treatment for dogs had received approval from the U.S. Food and Drug Administration. Simparica Trio is a once-per-month chewable tablet that protects dogs from three prominent types of parasites common to canines, heartworm disease, fleas, and ticks.

Clinical studies testing Simparica Trio demonstrated 100% efficacy in preventing the onset of heartworm disease, as well as a 98.9% effectiveness in fighting existing tick infestations in dogs. Simparica Trio also has a 100% efficacy in killing fleas eight hours after the initial treatment. While the treatment isn't as certain for other types of parasites, tests have shown that it's also reasonably reliable in eliminating roundworms (99% effective) and hookworms (94% effective).

"Simparica Trio makes it easier for dog owners to follow their veterinarians' recommendations for parasite protection because it covers the most common parasites in just one convenient chewable," said Chris Adolph, a senior veterinary specialist at Zoetis.
