Welcome to our shop Please ensure accurate and detailed measurements of your pet's chest before making a purchase. Refer to the size chart on the left for guidance. If your pet's size falls between two sizes, we recommend ordering a size larger. Our harness can fit most small dogs and all cats. It is suitable for breeds such as Chihuahua, Miniature Poodle, Maltese, Terrier, Yorkie, Mini Dachshund, and similar small-sized dog breeds. The harness is made of excellent quality materials, including ultra-soft and highly durable eco-friendly straps, lightweight and breathable air-mesh polyester material. It has been tested and is non-toxic. For added safety during nighttime walks, the harness features a reflective strip design that increases visibility in low light conditions. The harness is adjustable with a quick snap clip strap, double-stitched around a reinforced anchor hook, and a sturdy O/D-Ring for leash attachment. It also has non-breakaway emergency release clasps to provide extra pet protection during activities like jogging, running, or hiking. Our innovative no-choke design protects your pet's fragile trachea and throat, eliminating pulling, tugging, or choking. Note: 1. Please allow small size error due to manual measurement.
