Certifect for Dogs - 6 Month Purple 45-88 lbs

Certifect for Dogs 6 Month Purple 45-88 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.

Excellant tick prevention by prettyiz from Iowa07/23/2013

Certifect is the best product I have used for flea and tick control. I have 3 dogs who spend a majority of their time outdoors. This product does what it says and you won't be disappointed if you purchase it.

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!

not sure by dog lady from Florida02/19/2013

I have 6 dogs and split a tube with all of them. Fleas were back in two days.I did do the math correctly yet it didn't work. I have trouble with fipronil not working on my Florida dogs so I need to stay away from that ingredient

Best tick medicine I've ever used by John06/21/2013

We fish rivers in Arkansas and take our dog with us. Usually she returns from a trip covered with ticks and we need to bath her with medicated shampoo to rid her of them. Since using Certifect, she not only doesn't get ticks but the product lasts a full month even though she swims every day. No other tick repellent even comes close
