Simparica TRIO has kept my dog free from ticks, fleas and worms. During a bath once I found a dead flea on her which we suspect was from a walk in some tall grasses. The Simparica in her system killed the flea, stopping it from becoming an issue. She has not had any adverse reactions from the medicine, and we hope it stays that way!
