Frontline is effective for reducing the chance of your pet getting tick paralysis. No product is 100% effective for ticks though so make sure you still check your pet daily for deadly paralysis ticks.
Frontline needs to be applied more frequently for tick prevention than is does for treating fleas. It is really important that you apply it as directed.
Use Frontline Plus and apply it every 2 weeks for Ixodes ticks (the paralysis tick). Make sure you use the size appropriate for your dog.
