The usage will usually depend on the type of deshedding blade that you decide to opt for. Some of these blades use a single piece of metal with teeth on the side. Others rather come with a raked design. The usage for these particular types differs. The primary idea behind the blades, however, remains the same - to remove those loose hairs on your dog’s coat while they shed. If you use a blade with teeth on the edges, then make sure you do not place it too close to your dog’s skin. This can cause the blade to scratch your dog. Instead, keep it a bit off the skin, then pull the blade back. The teeth on the blade will then catch loose hair as it moves through your dog’s coat. With a rake, you will simply pull it through your dog’s coat like you would with a brush. This makes the entire process much easier, particularly due to the fact that the blades on these tools usually feature smooth edges. In turn, you do not have to worry about teeth on the blade causing scratches on your dog’s skin.
