    Certifect for Dogs - 6 Month Blue 23-44 lbs

    Certifect for Dogs 6 Month Blue 23-44 lbs is a fast acting, long lasting topical flea and tick treatment for dogs from Merial, the makers of Frontline. This formula offers an effective means for killing ticks, destroying the flea life cycle and eliminating chewing lice infestations. Your dog will gain tick relief within 6 hours of application, detaching ticks already attached to your infested dog. Certifect will completely kill the tick invaders in 18 hours. Containing tick problems protects your dog against commonly transmitted diseases including: Lyme Disease, Anaplasmosis, Ehrlichiosis, Babesiosis and Rocky Mountain Spotted Fever.


    Certifect also offers the same complete flea protection Frontline Plus. This means your dog will be completely protected from adult fleas, flea eggs and larvae. Certifect prevents re-infestation by eliminating the flea's ability to reproduce. This formula is safe, and can be used on puppies as young as 8 weeks old, and is also safe for breeding, pregnant and nursing dogs. Certifect is long lasting, offering a month of continual protection from ticks, and is waterproof so you don't have to worry about it washing off.

    Certifect can ship anywhere except New York.

    Usage Info

    It is a violation of federal law to use this product in a manner inconsistent with its labeling. Read entire label and enclosed directions and precautionary statements carefully. Do not allow children to apply product. Use on dogs ONLY. Do not use on cats, rabbits, or other animals. Do not apply more than once per month. DO NOT use on dogs diagnosed with diabetes or heart problems. Consult a veterinarian before using on dogs that are medicated, debilitated, aged or obese. DO NOT contact the treated area until completely dry.

    SIDE EFFECTS: temporary, lethargy and pruritis (itching) may occur, with the use of this product. If signs persist, or become more severe within a few days of application, consult a veterinarian immediately.

    To kill all stages of ticks, fleas and chewing lice apply topically to the skin of dogs or puppies (8 weeks or older) as follows: Open the child-resistant packing according to the instructions found on the inside back panel of the carton. Hold applicator upright away from face and body, cut applicator tip with scissors or twist to open. Place applicator tip through dog's hair to the skin level. Squeeze applicator, applying entire contents in two separate spots on the neck between the base of the skull and the shoulder blades where the dog cannot lick.

    Frequency of Application
    A monthly application of CERTIFECT kills ticks, completely breaks the flea life cycle and controls chewing lice infestations.

    Research demonstrates that CERTIFECT kills adult fleas (Ctenocephalides felis and Ct. canis), flea eggs, and flea larvae for up to three months.

    Certifect also prevents development of all flea stages for up to three months.

    Although Certifect can control fleas for up to three months, if there is a high risk of re-infestation or if the pet has fleas which may cause flea allergy dermatitis, a once monthly application may be needed.

    Certifect aids in the control of sarcoptic mange infestations. Apply once per month for at least two months for the elimination of mites.

    Certifect can also be used for the treatment and control of flea, tick and chewing lice infestations on breeding, pregnant and lactating bitches.


    The amount of active ingredients in the total volume is equivalent to 6.4% Fipronil, 5.8% (S)-Methoprene, and 7.6% Amitraz.

    Good Product but... by MF from CT01/19/2013

    Very happy with the product but not with the shipping method, Product was shipped in a padded envelope and the boxes inside were completely destroyed. This needs to be remedied.

    Extremely satisfied by maryf from Storrs, CT02/07/2013

    Product came promptly. Still could use better crush-proof packaging for shipping.

    by FutureDVM from College Station, TX07/13/2013

    Great product! Only product that seems to control the ticks around my area and I have tried them all. This is the ONLY product I will use on my pets now!
