Frontline Plus Dog Topical Flea & Tick Treatment

Nexgard For Dogs: The Frontline Solution in Flea and Tick Protection

Frontline Plus is a trusted topical flea and tick treatment for dogs, formulated to kill adult fleas, flea eggs, flea larvae, and ticks. Applied monthly as a spot-on treatment, it provides waterproof protection that continues working even after bathing or swimming.

Unlike oral flea medications, Frontline Plus is applied directly to the skin between your dog’s shoulder blades. Once absorbed into the oil glands, it spreads across the skin’s surface to provide continuous external parasite control.

Frontline Plus contains two active ingredients, fipronil and (S)-methoprene, that work together to kill adult fleas and disrupt the flea lifecycle by preventing eggs and larvae from developing.

Fleas and ticks are more than irritants. They can transmit diseases, trigger allergic dermatitis, and lead to infestations in your home. Consistent monthly application helps reduce exposure and protect your dog year-round.

Frontline Plus is available in multiple weight-based dosages to ensure accurate and effective treatment for dogs of all sizes.

How Frontline Plus Works

Frontline Plus uses a dual-action formula designed for comprehensive flea control.

Fipronil

Fipronil targets the nervous system of adult fleas and ticks, killing them after contact. It is stored in the skin’s oil glands and released continuously for long-lasting protection.

(S)-Methoprene

(S)-methoprene is an insect growth regulator (IGR) that prevents flea eggs and larvae from maturing, helping break the flea lifecycle before infestations can spread.

Together, these ingredients provide adult flea kill and lifecycle control in a single monthly application.

Why Flea & Tick Prevention Is Essential

Fleas can cause:

• Intense itching and scratching
• Flea allergy dermatitis (FAD)
• Hair loss
• Secondary bacterial infections
• Anemia in severe infestations

Ticks may transmit:

• Lyme disease
• Ehrlichiosis
• Anaplasmosis

Monthly prevention reduces the risk of parasite-borne illness and environmental infestations.

Frontline Plus Dosage by Dog Weight

Frontline Plus is available in weight-specific applicators to ensure proper dosing:

• Small dogs
• Medium dogs
• Large dogs
• Extra-large dogs

Using the correct dosage based on your dog’s weight is essential for safety and effectiveness.

Benefits of Topical Flea & Tick Treatments

Many pet owners prefer topical treatments because they:

• Do not require ingestion
• Remain effective after bathing
• Provide external parasite protection
• Help control flea eggs and larvae
• Are easy to apply once monthly

Topical options can be especially helpful for dogs that resist chewable medications.

Breaking the Flea Lifecycle

Successful flea control requires targeting multiple stages:

• Adult fleas on your dog
• Eggs laid in your home environment
• Developing larvae

By killing adult fleas and preventing egg development, Frontline Plus helps interrupt the infestation cycle before it escalates.
