Martingale Collars Help Prevent A Dog From Backing Out Of Its Collar. When There Is Tension On The Leash, The Martingale Will Reduce The Size Of The Collar By A Limited Amount, Preventing The Collar From Pulling Off Over The Head (When The Collar Is Properly Adjusted). When The Leash Is Slack, The Collar Relaxes To A Looser Fit As Determined By The Adjusted Size Of The Collar.

There Is A Second D-Ring Which Is Sewn Into The Collar Which Does Not Change The Size Of The Collar As The Martingale Does. Use This D-Ring To Attach Id Tags, Or For The Leash If The Limited-Slip Action Is Not Wanted. Important Safety Information: Never Leave This Type Of Collar On Your Dog When Its Playing With Another Dog Or When Unattended.

There Is A Risk Of Entanglement And Injury. This Collar Should Always Be Removed When The Dog Is Unattended. This Collar Does Not Have A Buckle And Is Slipped On Over The Head. 1-Inch Wide Martingale Collars Have Two Adjustable Size Ranges: 15-22 Inches Or 19-27 Inches.

To Determine Collar Size Be Sure That The Collar Is Large Enough To Go On Over The Head By Measuring Around The Heads Widest Point, From Under The Jaw, Over The Top Of The Skull And Back Down To The Start Point. Then Measure Around The Middle Of The Neck, Or Measure The Current Collar.
