INCLUDES MATCHING ROUND BRAIDED PARACORD LEASH! This collar is a new take a gentler approach to the more “traditional” martingale training collars. It’s made with a 1/4 inch soft polyester rope and paracord overlay meaning it’s very comfortable to your dog. The rope and overlay will not tangle in the hair of long-haired breeds. This collar allows you the control to correct your dog, without the harshness of a chain. The size options allow you to select a perfect fit for a variety of breeds. If you are unsure what size will work best, select “custom-size” at checkout and use the size chart to help measure your dog. Keep in mind the collar needs to be long enough to slip over your dog’s head. If you are more interested in using this collar for everyday wear for your pet’s ID tag, a tighter fit will suit you better. Because of the diameter of the heavy-duty stainless steel rings(1-inch), this collar is not recommended for toy breeds. However, a collar with a smaller diameter ring can be made upon request. The colors for this collar are completely customizable! Choose one color for the main rope and up to two colors for the braided overlay.
