This is a convenient car seatbelt attachment for dogs. The length is adjustable. It's designed to be used by attaching it to a harness or collar. It's the stretchy type made with rubber, so I think it's a bit gentle on the dog, which is why I use this type. It's very convenient ☺︎ The color is a cute, soft gradation, similar to the color in the third picture. Length: 60-88 cm Width: 2.5 cm
