You have a couple of different options when it comes to customizing your dog’s Cuban link dog collar. Some collars are available with a hanging letter toward the front of the chain. You can choose to purchase an all-in-one collar that has the appropriate letter for your dog’s name, or you can have something custom-made that hangs off the collar’s D ring instead of dog tags. As for engraving, that all depends on the material of the collar. For example, in most instances, you can’t engrave gold-plated jewelry because it flakes the surface and ruins the overall appearance of the chain. On the other hand, stainless steel can endure the laser engraving process, but it needs to be done correctly to protect its corrosion resistance.
