One collar per animal to be fastened around the neck. Remove the collar from bag directly before use. Unroll collar and make sure that there 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 thru the loop(s). Collar length of greater that 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.

After application of the collar, three reflector clips may be fixed permanently to the collar to increase the animal's visibility in the dark. Take the clips out of the bag. The clips should be evenly distributed on the non-overlapping part of the collar. The clips are correctly applied when a clicking sound is heard. For safety reasons once the reflectors are fixed to the collar the clasp closes permanently and cannot be re-opened.


    • For external use on dogs over 7 weeks of age up to 18 lbs (8 kg). Do not use on other animals. Do not get this product in dog's eyes or mouth.
    • 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.
    • 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.


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 reflectors, 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 or reflectors in mouth. Not intended for use on humans.
