The Safari Dog Diamond Nail File is specially contoured to conform to the shape of your dog’s nails. The diamond finish ensures a smooth nail and ease of use. Holding the toe firmly, file in a smooth stroke on the tip of the nail. File from the back to the tip, following the contour of the nail. Do not file in the opposite direction. A few strokes on each side of the nail will remove burs and leave your dog’s nails smooth and healthy.
