Frontline ^® for Dogs

Long-lasting, fast acting flea and tick control. Frontline contains fipronil, a flea adulticide. Fipronil works by affecting the parasite's (the flea's or tick's) nervous system causing paralysis and death of the parasite. Fipronil spreads over the pet's body with the body oils killing 98-100% of the fleas or ticks within 24-48 hours, and controlling transmission of tick-borne disease, such as Lyme disease.

Fipronil collects in the oils of the skin and hair follicles and then is released over time (up to 1 month) from the hair follicles onto the skin and hair.

Frontline stays on even with bathing, swimming, or exposure to sunlight. Approved for use on puppies 8 weeks of age and older.

Please note: Due to limited availability of Frontline products it has become necessary for us to limit purchase quantities to (10) 6-packs or (20) 3-packs of each item per order. Thank you for helping ensure Frontline remains available to more pets throughout flea & tick season. We apologize for any inconvenience.

Frontline^® provides convenient and effective flea and tick control for dogs and puppies over 8 weeks old. For dogs over 132 pounds use the appropriate combination.

Directions: To kill fleas and all stages of brown dog ticks, American dog ticks, lone star ticks and deer ticks (the major carrier of Lyme disease). Hold applicator upright and snap applicator tip away from face and body. Place applicator tip through dog's hair to the skin level between the shoulder blades. Squeeze applicator, applying entire contents in a single spot to the dog's skin. Avoid superficial application to the dog's hair. Only one applicator per treatment is needed.

Frequency of application: Research demonstrates that Frontline^® kills fleas up to three months and ticks for at least one month. A once monthly use is recommended where there is a high risk of reinfestation, if the pet has fleas, which may cause flea allergy dermatitis, or in situations where tick control is needed. When used monthly Frontline^® completely controls both flea and tick infestations. In areas with less severe flea infestations or in areas where ticks are not a threat, Frontline^® can be applied once every two to three months. Frontline^® remains effective even after bathing, water immersion, or exposure to sunlight. Avoid contact with treated area until dry. Do not reapply Frontline^® for 30 days.

We have two large dogs and we live surrounded by fields and woods full of ticks. Our dogs are free to roam and always had ticks on them when they returned home. Since we started using the Frontline product they have had NO ticks - not a one! We are so happy with this product. It's easy to apply and the dogs don't mind this once-a-month treatment one bit! Thanks for making tick season - and all year round - happier and healthier for my pets!

I bought BioSpot because it was half the price of some of the other brands. My dogs went out to the country for 2 hours and came back loaded with ticks. I just bought the more expensive Frontline recommended by my vet.
