This is a soft vest harness from PUPPIA. 【Size】 S size (Neck: 21cm, Chest: 29-33cm) 【Color】 Black / Beige Made of breathable mesh material, it is designed to reduce the burden on the dog's neck and trachea. It can be easily put on by putting it over the head and fastening the buckle. The chest size can be adjusted with the belt. It was used on a 3-month-old black and tan miniature dachshund. It was easy to put on and take off, and the dog didn't mind wearing it. Although there is some wear and tear, it has been washed by hand after use, so I think it is hygienically clean. This is a popular product loved in over 30 countries. Thank you for looking.
