It depends on which one suits you and your pup more. The convertible in the Convertible Z Harness refers to its hybrid design between the "head-in" and "step-in" harnesses. It is one of our most unique harnesses and has many features. Here's to name a few: Convertible Hybrid Design - The d-rings are positioned further back closer to your dog's torso. This allows the pulling force to distribute around its chest, not its underarm, which could cause armpit rashes. Click here for for more on the Convertible Hybrid Design. Fastener Neck Closure - easy adjustment of the neck size for a more secure fit, something you don't find with traditional head-in harnesses. Shock Absorbing Design - cushions and softens the sudden shock when your pup pulls so it's not so hard on your arms.
