This is a 3/4" wide spiked leather collar, hand-crafted with latigo leather. It is available in black, pink, purple, navy blue, red, 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.
