The only difference between the Slip over-head and Buckle-neck version is that the Buckle-neck version has a buckle on the neck loop.
The added buckle allows you to clip the harness around your dog's neck (similar to a collar) rather than having to slip it over top of your dogs head. They are exactly the same in design, functionality, etc. If your dog has a large head or doesn’t like things slipped over the top of his head, we suggest the Buckle-neck version.
