Certifect for Dogs

Grand Sale

Certifect for Dogs is Merial's new long-lasting, monthly topical flea and tick preventative.

Certifect for Dogs works just like FRONTLINE Plus with the addition of amitraz, a powerful tick-killing ingredient.

It kills ticks and adult fleas rapidly and destroys the flea life cycle by killing flea eggs and larvae as well.

Most topical tick treatments can take 24-48 hours to kill ticks, but Certifect for Dogs begins killing ticks in 6 hours and kills up to 100% of ticks in 18 hours. Furthermore, it is the only topical tick product that forces ticks to detach from an infested host.

Certifect for Dogs provides complete flea control by killing adult fleas and preventing development of all flea stages.

It not only kills fleas and ticks rapidly, but it continues to protect dogs from fleas and ticks for a whole month - even when swimming or bathing.

In addition, Certifect for Dogs kills chewing lice and can also be used to control chewing lice and sarcoptic mange infestations.

More Information

How It Works

Once you have applied Certifect for Dogs to your dog, it starts killing pre-existing fleas and ticks quickly, with the help of fipronil, (S)-methoprene, and amitraz. Both Fipronil, a slow-acting poison that disrupts the central nervous system of fleas and ticks, and (S)-methoprene, an insect growth regulator that kills flea eggs and larvae, are long-lasting and work quickly to rid dogs of fleas and ticks. These two ingredients are stored in the sebaceous glands of your dog's skin and are wicked out of the hair follicles allowing for month-long protection against fleas and ticks. Certifect for Dogs also contains a small amount of amitraz, an insecticide that increases the tick-killing potency of fipronil. Unlike fleas, ticks tend to stay in one place on a host's body, but amitraz stimulates tick movement; therefore, increasing a tick's exposure to fipronil an effective tick-killing ingredient.

For dogs without flea and tick infestations, it works as an effective, long-lasting monthly topical preventative against fleas and ticks - just apply once a month.

Ask a Vet winner

I have 12 yr. old Male Black Lab that weighs 133 LB & was just diagnosed with heart worms. Are there any other options for him other than the Immiticide injections? I�m worried about this option because of the risk with his age. A couple veterinarians have told me to treat with heartgard for 12 months & may get negative test results in that time if I was needing a more affordable & safer option? Only other problem, Jordan has arthritis in his hip & currently takes 2 Rovera 100 mg. tablets dai...?
