The ZeeZ Hydrophobic Pet Socks are the perfect indoor/outdoor sock! With a non-slip base, these socks can help prevent your dog from slipping on tiles, scratching floorboards and furniture, as well as keep their feet warm and dry. The socks have a hydrophobic treatment allowing the sock to be water resistant. When your pet walks through puddles or water touches the sock, the water will repel off the sock*. Perfect for light use in puddles and the garden. Over time, wear and tear to the product will wash away the hydrophobic treatment, this is why it is best to wash the sock in water without washing detergent. These socks are also great to use after surgery and for allergies. PACK SIZE: 4 socks per pack.
