As a dog owner myself, I've experienced my puppy chewing and breaking her ordinary collars. These collars are carefully handwoven to be long-lasting, durable and attractive for all dogs.  These collars are made of of 550 paracord ropes. Each collar includes durable, arched side release buckles and 3/4 inch non-welded nickel plated steel d-rings. Made in USA. Each collar is made to order, customer selects their size and color.  please message me if you have any further questions. Every order will ship within 5-7 business days.
