Your animal is most likely to get clammy and uncomfortable in wet or damp conditions if the breathability of their waterproof rug or coat is impaired. If the outer fabric absorbs water, the rug/coat can lose up to 70% of its breathability. Therefore, the Durable Water Repellency (DWR) on the outer fabric of your animal rug/coat must be maintained to ensure comfort. Nikwax Rug Wash• will revitalise the DWR and therefore breathability of your animal rug/coat, keeping your animal comfortable. Some animals, including dogs and horses, can be subjected to the elements whilst outside. When it rains, waterproof rugs and coats are used to keep them dry and comfortable. It is important that these waterproof fabrics allow moisture vapour to pass through them, or 'breathe'; otherwise moisture cannot evaporate, so will condense on the inside of the item. Additionally, if the outer fabric absorbs water and 'wets out' the item's breathability will be reduced. Both of these situations will lead to your animal getting clammy, cold and uncomfortable. The breathability of rugs and coats can be maintained by ensuring the Durable Water Repellency (DWR) is kept in good condition. Nikwax Rug Wash• will revitalise the DWR preventing water absorption and maintaining breathability to keep your animals dry and comfortable.
