UT Martingale Collar
If your interested in a matching clip/tag collar they are available under the clip collar tab.
Product sizing and material information
All of these martingale collars are made with steel hardware, the D-ring is welded to prevent separation. The inner material is seat belt strapping with a breaking strength of 3000 lbs. 100% nylon thread rated for outdoor use so if your dog gets it wet the strength is still there. The clip collars are made with 1 inch seat belt material and plastic slides and plastic clips. I have found the metal clips are too difficult to get off. Machine wash in warm water and dry flat.
Medium martingale collars fit a neck size from 15-19 inches and are available in 1.5 inch or 2 inch Martingales. Most Greyhounds are this size.
Large martingale collars fit a neck size from 18-25 inches and are available in 1.5 or 2 inch Martingales. Most other dogs are this size due to their head being bigger than their neck.
