This is a 3/4" wide spiked leather collar, hand-crafted with latigo leather. It is available in black or burgundy and in any length you need. The rivets we use are stainless steel. This is a very high quality collar at a great price! Each collar has an adjustment of 5 inches, so if your dog is not quite full grown, make sure you order the collar to fit in one of the smaller holes so that the dog can grow into it.
