No matter how safe you think dogs' collars & harnesses are, there's still the possibility that dogs might slip out of them. Therefore, in honor of February's responsible pet owner month, we created this safety clip to help you back up your dog's collar. Simply adding this double side clip to attach the collar to the harness/leash gives you additional security if any of those fail to work correctly. Let's keep our pets safe by simply adding a backup! Specs: Total length 9" (includes both swivel snaps) Biothane length 4" Strap width: 5/8" Care Instruction If the BioThane ever gets dirty, just rinse it with water and a little bit of soap. It'll look good as new again!!  Please keep in mind that the matte black hardware is nickel and brass-plated. It will wear off over time of use. Please also inspect the gear before each use for wear and tear that could cause safety issues. We offer a lifetime warranty if there's any hardware failure, but not normal wear and tear.
