Bravecto Chews is the first oral chew for dogs to provide up to 12 weeks of protection against fleas and ticks. One chew provides broad-spectrum and long-lasting protection that starts to kill fleas within 2 hours and controls 4 tick species: black-legged tick (a.k.a. deer tick), American dog tick, brown dog tick, and lone star tick. Bravecto Chews eliminates current flea infestations and prevents new ones from developing for 12 weeks. With one chew, Bravecto Chews is easier to give and less to worry about for you! Bravecto Chews requires a prescription from your veterinarian.
