Merial does not make different mixtures of flea products to sell in different territories all over the world..they make only one version of a product then simply change the packaging and most importantly THE PRICE! There is only one factory in the world that produces Frontline products and that is the Merial factory in France. There is no evidence worldwide of ANY FAKE Frontline Products. When someone refers to a Frontline Product as “fake” they are simply not in the know about how Merial packages its Frontline to be sold in different territories at different price points.

Why should the U.S.A. pet owners have to suffer higher prices than pet owners in any other territory? It is your legal right to shop in other territories if you find the EXACT same product in another territory for less money. These products are safe and legal in the U.K. as it is the same product sold here in the U.S. We will offer the Combo as inexpensively as we can in hopes to change the prices in the U.S to match other territories where the products are more fairly priced.


  • Effectively kills immature stages of fleas
  • Frontline Plus kills the ticks that may carry Lyme Disease!
  • Easy to apply topical monthly flea and tick product protects all month long

In addition to fipronil, which kills adult fleas, Frontline Plus contains an important addition: (S)-methoprene. Methoprene is an ingredient that kills flea eggs and larvae, which keeps ALL stages of fleas from developing and bothering your pets and your family, not just adult fleas. Methoprene mimics the juvenile growth hormone of fleas, keeping the larvae from molting and developing into more mature forms. Frontline Plus is long-lasting, fast acting flea and tick control you apply on the skin once monthly.

The fipronil in Frontline Plus 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. It works by affecting the flea’s or tick’s nervous system, causing paralysis and death. 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.

FrontlineĀ® Plus for dogs and puppies over 8 weeks old. For dogs over 132 pounds use the appropriate combination.

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 FrontlineĀ® Plus 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 FrontlineĀ® Plus completely controls both flea and tick infestations. In areas with less severe flea infestations or in areas where ticks are not a threat, FrontlineĀ® Plus can be applied once every two to three months. FrontlineĀ® Plus remains effective even after bathing, water immersion, or exposure to sunlight. Avoid contact with treated area until dry. Do not reapply FrontlineĀ® Plus for 30 days.

Q. Do I need a prescription to order?
A. No. This is an over-the-counter flea & tick product available without any prescription required.

Q. How quickly does FRONTLINE flea and tick protection kill parasites?
A. Research has shown that FRONTLINE for dogs will kill 100% of your dog’s fleas within 24 hours and kills 100% of your dog’s ticks within 48 hours of application.

Q. Do fleas and ticks have to bite my dog for FRONTLINE to work?
A. No. FRONTLINE supplies your dog with protection if fleas simply come into contact with your dog’s coat within the post-application time periods mentioned above.

Q. I just applied FRONTLINE, but I still see active fleas. Why?
A. Fipronil, an active ingredient of FRONTLINE, works by blocking stabilizing ions in the neurons of invertebrates like fleas. Without the stabilizing ions, the fleas die from hyperstimulation. This means that the fleas may become slightly more active just before they die. However, you should rest assure that this is a sign that FRONTLINE is working.

Q. I treated my dog with FRONTLINE, but I still see fleas in my home. Why?
A. The fleas you see may have hatched from flea eggs that were laid before you began using FRONTLINE for dogs. Regular application of FRONTLINE flea and tick protection to your dog will break the flea’s life cycle.

Q. How does FRONTLINE kill fleas before they can lay eggs on my dog?
A. An adult flea must be present on your dog for at least 24 to 36 hours before it can lay eggs. Research indicates that FRONTLINE will kill your dog’s fleas within 24 hours of application–before the fleas can lay eggs.

Q. Which FRONTLINE product is right for my dog?
A. FRONTLINE Plus is a convenient once-a-month topical product offering the longest-lasting, most complete protection against adult fleas, flea eggs and larvae, and all four major species of ticks. FRONTLINE Top Spot provides fast-acting, long-lasting flea and tick control for dogs. Ask your veterinarian which FRONTLINE product is the best choice for your dog.

Q. Can FRONTLINE be reapplied before the 30-day treatment interval is up?
A. FRONTLINE products should not need to be applied more than the label recommendations.
