Product Description This is from a long-established Finnish dog goods brand. They manufacture a wide range of products, including apparel, harnesses, and collars. For those who love Nordic design, this brand is by "Ristomatti Ratia." He is a famous Finnish designer, and his designs, such as the Marimekko sling bag 301, have received high praise. This is a harness with a soft cushion that fits your dog's body, and its Y-shaped design reduces strain on your dog's neck and trachea. Choosing the right size is very easy; just measure the size of your dog's head. Select the size closest to your dog's head measurement. The chest circumference can be widely adjusted. *The size notation for the Y-shaped harness refers to the neck circumference of the harness. Please measure your dog's head and choose the harness size that is as close as possible. However, you cannot use a size smaller than your dog's head size (as it is a type that is put on from the head, it will not be possible to put it on).* Size 80: Neck circumference 80cm, Chest circumference 80cm to 100cm, Width 5cm *If you are unsure, a smaller size will likely fit better. *The chest circumference can be adjusted to some extent.
