Mesh material M size nursing harness, easy to use with a front-opening design. It supports the entire chest, so there's no pressure. My dog was spinning around a lot, so it couldn't support him, but I think it's very good for simply supporting and walking your dog. - Size: M - Material: Mesh 100% Polyester (Strap part: Polypropylene tape) - Color: White - Design: Front-opening type - Purpose: Nursing harness Shiba Inu, Corgi, Cocker Spaniel, Sheltie, etc. For dogs with a front leg base circumference of 70-83cm. Thank you for viewing.
