If your dog’s weight is greater than 2.8 lbs and you want to cover different tick species (American dog tick, Black-legged tick, Lone Star tick, and Gulf Coast tick) along with the prevention of Lyme disease and control of flea allergy dermatitis (FAD), then consider Simparica Trio.

Although both treatments are equally efficient in providing comprehensive protection against multiple parasites, choose the one that suits your canine’s individual needs and requirements and always consult your vet for tailored recommendations.
