The clasp, (buckle) is what attracted me to this. One that is a bit more difficult for my pup to remove, but when it arrived, it is elegant for a dog collar. I adjusted it to size, put it on and away she went. Once she realized that she could not slip out of it, she left it alone. That is a great sell for me. To know that it is worth the money, worth the effort and in the long run will be worn out before it is removed by her.
