. We bought it and when we buttoned it, we closed it. The nylon material was worse and spread. My husband was able to easily undo the clasp. Wouldn't recommend it. We bought this belt as a comfortable collar for a very large breed dog. Puppy Italian Mastiff Cane Corso. He's very strong, like a seven-month-old puppy, but weighs over 100 pounds. His neck is 28 inches and he's still growing so he needs something very strong. My husband was in the Navy and had the idea for a military belt with a metal buckle. The Spartan, my pup, would tear him to pieces at the first sight of a rabbit hopping around his yard. The husband simply pulled the clasp and the nylon strap unwound and slid out of the clasp without resistance. I do not recommend. So I will only use it myself. Should have held up better.
