Martingale collars are our preferred style of collar for extra safety. They have a loop which will tighten if the dog pulls, which will prevent them from slipping the collar. Available in 5 fun patterns. Matching leash available.
 
This collar is made with ribbon on one side and strong nylon webbing on the other and is only available in a 1″ width.  Sturdy metal D-ring and adjusting buckle.
