Directions for Use:
Do not open until ready to use. Dust will form on collar during storage. Do not get dust in mouth or eyes. Take the collar out of the packaging and stretch to full length. The tabs that held the collar in place will fall off when stretching; pull on any remaining tabs to remove them. Bend the buckle in half between the holes in the buckle, so that you can easily pass the end of the collar through both holes. Place the collar around your dog's neck. Feed the collar through both holes, notches facing out. Fit to the neck of the dog. The collar must be worn loosely to allow for growth of the dog and to permit the collar to move about the neck. Generally, a properly fitted collar is one that, when fastened, will snugly slide over dog's head, and two fingers can be placed between the collar and dog's neck. Leave 1 or 2 extra inches for collar adjustment, cut off remaining excess collar and dispose of in the trash. Do not use on dogs under 12 weeks of age. Wash hands after installing collar on dog. Replace collar every 6 months, or sooner if needed. Consult a veterinarian before using this product on debilitated, aged, pregnant, medicated, or nursing animals.

DO NOT USE ON CATS.
