When to Start Applying Frontline for Dogs?

Frontline is a product designed to provide comprehensive flea and tick prevention for dogs. Frontline is a topical flea repellent that provides protection when applied in a simple-to-use applicator to the back of your pet's neck. Frontline is available without a prescription, and most vets agree that the product is safe for the majority of dogs.

  1. When to Start Applying Frontline

    • According to Ask the Vet, Frontline is safe for dogs ages 8 weeks and older. Frontline should be applied as soon as a dog is 8 weeks old, or as soon as you get an older dog. Frontline can prevent new fleas and can work to eliminate fleas at all stages of life, so once you begin applying Frontline, the topical treatment should be applied on a regular schedule.

    Monthly Application

    • Frontline should be applied monthly in both warm- and cold-weather months. Ask the Vet says the product kills 100 percent of fleas within 18 hours of application, and all ticks within 48 hours of application, by hyperstimulating the pests. With regular application, the manufacturer reports that your dog should be protected from discomfort and disease caused by fleas and ticks.

    Is Reapplication Necessary?

    • Frontline is waterproof and does not come off if you bathe your dog or if your dog goes swimming. Therefore, reapplication is not necessary except according to the monthly schedule recommended by the manufacturer. Flea Wars recommends bathing your dog before applying Frontline and making sure that your dog is totally dry before applying the medication to the fur on the back of his neck.
