Bringing a new dog home or maintaining care for your current pet means protecting them from hidden dangers like fleas and ticks. FRONTLINE® PLUS for Dogs delivers fast-acting, month-long flea and tick protection that pet owners trust. As the #1 name in flea and tick protection, this waterproof formula kills fleas, larvae, eggs, ticks, and chewing lice through direct contact with your dog’s hair and skin .
Why Your Dog Needs Flea and Tick Protection
Fleas and ticks aren’t just annoying—they pose serious health risks to your dog. Fleas are tiny blood-feeding insects that can cause itchiness, skin irritation, and even transmit diseases. Ticks, which are arachnids with eight legs like spiders, feed on blood and can carry dangerous pathogens .
Monthly prevention is essential because:
- One flea infestation can quickly explode into hundreds of parasites
- Ticks can transmit life-threatening diseases like Lyme disease
- Fleas lay eggs that continue reproducing even after adult fleas are killed
- Year-round protection is recommended in many parts of the country
FRONTLINE® PLUS addresses all these concerns by killing fleas at every life stage: adults, larvae, and eggs .
What FRONTLINE® PLUS for Dogs Kills
FRONTLINE® PLUS for Dogs provides comprehensive protection against multiple parasites:
| Parasite Type | What It Kills |
|---|---|
| Fleas | Adults, larvae, and eggs |
| Ticks | All major tick species |
| Chewing Lice | Entire life cycle |
This triple-action formula ensures your dog stays protected from the most common and dangerous external parasites .
How FRONTLINE® PLUS for Dogs Works
Once applied to a single spot on your dog’s skin, FRONTLINE® PLUS spreads across your dog’s entire skin surface through natural skin oils. The product is stored in the oil glands of the skin, creating a protective barrier that lasts for 30 days .
Fleas and ticks are killed through contact with your dog’s hair coat and skin—no biting required. This contact-killing action means parasites die before they can bite your dog or transmit diseases .
How to Apply FRONTLINE® PLUS for Dogs
Proper application is crucial for maximum effectiveness. Follow these steps:
Step 1: Remove Applicator from the Blister

Step 3: Apply the Entire Contents
- Part your dog’s hair between the shoulder blades
