How often should I apply FRONTLINE Shield for Large Dogs to protect my dog from fleas and ticks?

[McGenevieve]

To ensure your large dog is protected, apply FRONTLINE Shield Flea and Tick Treatment monthly. This schedule is recommended to effectively manage existing flea, tick, and chewing lice infestations and prevent new ones. Applying FRONTLINE Shield monthly starts killing ticks within an hour and fleas in about five minutes, beginning two days after application. This monthly treatment eliminates fleas, flea eggs, and larvae and repels ticks, stable flies, and mosquitoes for a month. Always follow the product instructions carefully and apply consistently for continuous protection for your pet.
