Simparica Chewables for Dogs vs Bravecto Chews for Dogs

Both are prescription isoxazoline chews that kill fleas and ticks, and both are well tolerated by most dogs. Simparica is the better fit if you want a monthly routine and fast flea kill, since it starts killing fleas within hours of dosing. Bravecto is the better fit if you would rather dose every 12 weeks and skip two monthly reminders out of three. Reviewers and owners on both sides mostly report the same things: effective flea and tick control, and occasional stomach upset or vomiting after a dose.

• Choose the Simparica Chewables if you want a once-a-month chew with rapid flea kill and a small, liver-flavored tablet that is easy to break into food.
• Choose the Bravecto Chews if you want one dose to cover a full 12 weeks and prefer fewer dosing days over the year.
