These Slip Collars were designed from the advice from professional trainers. 
 
Made from 3/8” Heavy Duty Nylon Webbing with a tensile strength of 1,000 pounds, welded metal O-Ring and D-ring and a spring-loaded block lock to ensure that your line is securely fastened to stay where you want it.  Lightweight but durable enough for your training needs. 
 
Measure from the largest portion of the dog’s head for accurate sizing.  The size is measured according to the total length of the collar line.
