Query: Good product, but wish the neck portion had more holes for adjusting size

I don't really use it that often, but product is as described. The piece that can be put in or pulled out came in handy. The only problem I had, is there isn't enough holes in the part that goes around the neck, so my dog pulled it off. Not a big deal, we can add another one.
