Thank you for viewing. It has a Velcro fastener, making it easy to put on and take off. The size is S, perfect for small dogs. My dog is a 2.9kg Toy Poodle, and it fits without any problems. There have been no issues with catching things either. I used it to prevent stool eating. I bought a lot, but since the stool eating has calmed down, I'm selling it. How about giving it a try? - Size: S - Color: Blue - Material: Denim-like fabric It's new and unused, but please refrain from purchasing if you are sensitive to items that have been handled by someone else.
