The Fuzzywumpets Fleece-lined Limited Slip Collar is designed to keep your dog both safe and comfortable.  Like a traditional martingale collar, Limited slip collars help control pulling behaviors and prevent escape by incorporating a smooth action slip section.  The collar goes on loose, easily slipping over the dog's head. If the dog pulls in any direction, the collar tightens down just enough to keep the dog from slipping the collar, but not enough to choke him. The microplush padding prevents chafing and allows airflow around the dog's neck.  Available in standard non-adjustable and adjustable sizes.  Non-adjustable sizes offer more fleece coverage, while adjustable sizes are great for growing dogs or for a custom fit. Machine wash, line dry.
