The adjustable harness easily adjusts to the dog's specific size. It brings comfort and safety to the animal, perfect if the dog pulls on the leash too often. The harness is padded on the inside for the dog's comfort and also allows perspiration to pass through. This ergonomic Y-shaped harness allows the animal to move freely and does not block its muscles during its outings. Material: our harnesses are lined with neoprene. From the rubber family, it is a resistant, light, and elastic material that brings all the comfort to the dog during walks. Made in China
