This is a Kuuk Couture Terahertz dog shirt, size LT. It's thin and stretchy, so I think it's easy for your dog to wear. The hem, sleeves, and collar have frills, making it very cute. It's cute on its own, but it's also very cute and easy to use as an inner layer for layering. Terahertz has an effect on weak parts of the body. It is said to have excellent penetration ability and promotes health. It also has the aspect of recovery wear, and is recommended for all dogs, but it is especially effective for senior dogs and dogs that are often sick, so it can also be used as a nursing care support garment. Please understand that this is a used item. Shipping will be either Rakuraku Mercari or Yu-Yu Mercari, so please be aware of that.
