Seresto® Collar for Dogs provides long-lasting flea and tick protection in a convenient, easy-to-use collar. Designed to release active ingredients slowly over time, the collar delivers continuous protection for up to eight months without the need for monthly applications.
The odorless, non-greasy design allows dogs to wear the collar comfortably during daily activities. Seresto collars are adjustable for a secure fit and are suitable for dogs that need extended flea and tick prevention as part of a regular care routine.
Active Ingredients
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.
Store in the original packaging in a cool, dry place until ready for use. Keep out of reach of children and animals when not in use. 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.
