The Limited Slip Collar features two d-rings. Attach your lead to either ring, and use the other for tags. Or keep both rings free for different uses. One d-ring features a limited 2 inch slip. When your dog pulls or tries to duck out of the collar, it will tighten two inches. This gives handlers more control. It also enables collars to be fitted looser and in a more comfortable manner. If you prefer using a traditional hook up, then attach your lead to the second d-ring and it will function just like any other collar. The collar is fully adjustable and available in three sizes. The collar is ¾" wide with parts that are slightly lighter than our 1" collar. Pick from a wide variety of solid colors.
