Never Alter Volume: Certifect is strictly pre-measured for single-use delivery. Do not manually split, divide, or alter the fluid contents under any circumstance, as the active elements are distributed across a dedicated dual-cavity structure.
Application Method: Part the hair structural layout along the dog’s spine (typically between the shoulder blades) until skin layer visibility is confirmed. Express the complete pipette content cleanly onto one or two separate skin contact points.

When choosing a Certifect Dosage for dogs, it is important to remember that Certifect is not an oral treatment, it is a weight-based topical treatment for fleas, ticks and chewing lice. Using the appropriate sized pipette for your dog’s weight ensures that you give safe, effective protection without the risk of over or under-dosing. This guide will have a Certifect dosage calculator for dogs by weight, dosage chart and application instructions, safety considerations, benefits, side effects, and answers to common questions to help you use the product correctly.
Developed by the makers of Frontline, Certifect for Dogs is a quick-drying, waterproof topical treatment for dogs that works against parasites. It contains a combination of fipronil, (S)-methoprene and amitraz to eliminate adult fleas, ticks, flea eggs, flea larvae and chewing lice, interrupt the flea life cycle and aid in the prevention of reinfestation.
Certifect medication also contains the active ingredient amitraz which gives extra tick control; with most tick infestations reduced to zero in 18 hours and the product starting to work in about 6 hours. It also aids attached ticks to come off the skin, decreasing the time of attachment, and therefore decreasing the risk of tick-borne diseases like Lyme disease, Ehrlichiosis, Anaplasmosis, Babesiosis and Rocky Mountain spotted fever.
What is Certifect Dosage For Dogs?
Flea and tick treatment for dogs using a weight-bracket and Certifect only pre-measured, single use topical pipette. Certifect is not a treatment which can be manually adjusted for fluid, but instead a specialized dual-cavity treatment made up of active ingredients (Fipronil, (S)-Methoprene, and Amitraz) which can never be split, divided, or changed without compromising safety and efficacy.
The accurate dosing is done strictly by matching your dog’s weight to one of four (4) color-coded weight ranges corresponding to the smallest (4.4 lbs) to the extra largest (132 lbs) and applied directly to the dog’s skin along the spine once every 30 days. For safety reasons, Certifect dosing should not be used to treat any puppies younger than 8 weeks or any dogs less than 4.4 lbs (2 kg) in weight.

- Application Location: Part the fur along the spine (usually between the shoulder blades) until the skin is visible. Apply the entire pipette contents directly onto the skin at one or two spots.

What is Certifect?
Certifect dosage for Dogs is a Merial topical flea, tick and chewing lice treatment that lasts for 30 days. It is formulated with three active ingredients—fipronil, (S)-methoprene and amitraz, that act together to kill adult fleas and ticks, prevent flea eggs from hatching, kill flea larvae and break the flea life cycle to help prevent reinfestation. Amitraz gives Certifect the extra tick-killing power: kills ticks in as little as 6 hours, up to 100% of ticks in 18 hours, and unique among topical tick treatment products, causes attached ticks to drop off the dog’s skin.
In addition, Certifect will eliminate chewing lice and can be used to help control sarcoptic mange infestations. It is waterproof, which means it will keep working on a dog for one month, even if they get wet by swimming or bathing. Certifect is a 2-chamber applicator that is applied once a month in 2 locations and is designed for dogs and puppies 8 weeks or older that weigh at least 5 pounds. The drug is translocated throughout the skin and hair coat which can take up to 24 hours. Ideally, do not bathe your dog for 24 hours after you apply it.

How Certifect Works for Dogs
Certifect for Dogs is a topical, once-monthly parasite control treatment that begins to act quickly to eliminate current flea, tick and chewing lice infestations and helps prevent future ones. It contains the combination of 3 active ingredients that offer a broad spectrum of action in the life cycle of parasites: fipronil, (S)-methoprene and amitraz.
The active ingredients spread around your dog’s skin and coat after application and are retained in the sebaceous (oil) glands, being slowly excreted via the hair follicles. Long-lasting protection against fleas and ticks for up to one month.
The effect of each ingredient:
- Fipronil interferes with the central nervous system of flea and tick, causing death to the adult when it has contact with the treated skin and coat.
- (S)-Methoprene is an insect growth regulatory (IGR) that disrupts the flea life cycle by blocking the growth of flea eggs and larvae and thus preventing further reinfestation.
- Amitraz improves tick control by encouraging ticks to move, which will cause them to come into contact with fipronil and also make it more likely for attached ticks to disassociate from the dog’s skin.
When the product is applied to the skin, any parasites that come into contact with the surface containing the active ingredient(s) are killed. Certifect is an effective monthly preventative for dogs not already infested, one application monthly to prevent future tick and flea infestation.
