The high-cut belly design is a thoughtful touch that keeps the fabric away from sensitive areas, ensuring your dog stays dry and comfortable during movement. Since it is made of machine-washable cotton, cleaning up after a day of outdoor adventures is effortless. Just make sure to consult the size chart beforehand to ensure that perfect summer fit.
