2. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar.
3. Insert end of the collar through the buckle. Adjust the collar around the dog or cat’s neck without tightening it too tight (as a guide, it should be possible to insert two fingers between the collar and the neck).
4. Pull excess collar through the loop(s) and cut off any excess length extending 1 inch (2 cm) beyond the loop(s).
5. Seresto® comes with three optional reflector clips that can be attached to the collar for additional visibility at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.
