Classic rain slickers for your dog -- lightweight, waterproof rain gear that is a perfect all-season raincoat. Fits comfortably over a sweater for warmth—and style! Velcro closing under the neck and body makes it easy and quick to put on for those unexpected showers, take off when the sun comes out. Slickers have a 100% cotton lining in tan. Sizing: For coats measure the exact length of the dog's backbone from the base of the neck to the base of the tail. Choose the size that is closest to the tail without going over.
