Our new socks are made with 100% cotton. They are made of very soft cotton and feature an anti-slip dog sole. They are machine washable, but line dry to avoid shrinkage. Traction: Grips on slippery surfaces and protects your hardwood floors from nail scratches. Protection: For dogs with foot injuries, allergies, and sensitive feet Tips: Clip the dog's claws before wearing. Dogs may prance when first wearing the socks. It helps to distract them with a treat or their favorite toy until they get used to them.
