The Avery Sportding Dog Dogsorber is a convenient way to always have a towel handy to dry your dog in the field. Constructed out of a synthetic sponge material known as PVA (polyvinyl alcohol), it will absorb up to 12 times its dry weight in water. Don't just use it on your dog; it is also great for drying valuable equipment, ATVs, and boat seats. Rinse thoroughly with warm water before first use. May be stored damp but not recommended. Machine washable. Dimensions: 26"L x 17"W.
