DIRECTIONS FOR USE

It is a violation of Federal Law to use this product in a manner inconsistent with its labeling. Do not contaminate feed or food.

HOW TO APPLY

One collar per animal to be fastened around the neck.

Remove collar from protective bag directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar.

Insert end of the collar through the buckle. Adjust the collar around the animal’s neck without tightening it too tight or leaving it too loose. As a guide, it should be possible to only insert 2 fingers comfortably between the collar and the neck. Pull excess collar through the loop(s). Collar length of greater than 1 inch (2 cm) beyond the loop(s) should be cut off unless it is on a growing puppy, where some additional length may be needed for adjustment as the animal grows.

The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when puppies are rapidly growing.

This collar is designed with a release mechanism. In the unlikely event of a dog being trapped, the dog’s own strength is sufficient to widen the collar to allow for quick release.

Replace the collar after 8 months for optimal flea and tick protection.

PRODUCT INFORMATION

Kills fleas which may cause flea allergy dermatitis (FAD) or flea bite hypersensitivity (FBH).

Seresto kills existing fleas on dogs within 24 hours. Reinfesting fleas are killed within 2 hours with protection against further flea infestation lasting eight (8) months. Pre-existing pupae in the environment may continue to emerge for six (6) weeks or longer depending upon the climatic conditions.

Seresto aids in control of flea larvae in the dog’s surroundings following contact with a Seresto-treated dog.

Ticks already on the dog prior to treatment may not be killed immediately after collar application and may remain attached and visible. At the time of application remove ticks already on the dog. The prevention of infestations with new ticks starts within 48 hours after application of the collar.

Re-infesting ticks are repelled and/or killed as quickly as 6 hours.

Kills lice on dogs.

Aids in the treatment and control of Sarcoptic mange on dogs.

Seresto is water resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. In order to maintain an eight-month duration, dogs must not be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to 5 months for flea control and reduced to 7 months for tick control.

Occasionally scratching may be observed in animals that are not used to wearing collars during the first few days after fitting. Ensure that the collar is not fitted too tightly. Slight hair loss and mild skin reactions due to the mechanical irritation of the collar may occur at the application site which usually recover within 1 or 2 weeks without the need for collar removal. For further guidance regarding individual animal sensitivities, see information below.

In case of loss of collar, a new collar may be applied immediately. Do not attach a leash to the collar as this may cause breakage.

Keep the collar in the bag and in the outer packaging until use. As with any pesticide product, do not allow small children to play with the collar, or to put them into their mouths. Avoid contact with eyes, skin or clothing. Wash thoroughly with soap and cold water after fitting the collar. People with sensitivity reactions to the ingredients of the collar should avoid contact with the collar. Choking hazard. Contains small parts. Do not place collar in mouth. Not intended for use on humans.

For external use on dogs only. Do not use on other animals. Do not use on puppies under seven weeks of age. Do not get this product in dog’s eyes or mouth. As with any product, consult your veterinarian before using this product on debilitated, aged, breeding, pregnant, or nursing animals. Individual sensitivities, while rare, may occur after using ANY pesticide product for pets. Rarely, mild application site reactions may occur, such as scratching, redness and hair loss, which usually recover within 1 to 2 weeks without the need for collar removal. In some cases, a temporary collar removal and bathing may be recommended until symptoms have disappeared. In very rare cases, application site reactions such as dermatitis, inflammation, eczema or lesions may occur. In these instances, collar removal is recommended. If signs persist, or become more severe, consult a veterinarian immediately. If your animal is on medication, consult your veterinarian before using this or any other product. If your dog is experiencing an adverse event, contact your veterinarian and call 1-800-422-9874.

The patented continuous release technology ensures that both active ingredients are slowly and continuously released in low concentrations from the collar towards the animal. This avoids peak concentrations and ensures that concentrations of both active ingredients are present in the dog’s haircoat during the entire efficacy period. The active ingredients spread from the site of direct contact over the skin surface.

Do not use container for food storage or other purposes.
