Why do I need a dog and cat nail clipper? For dogs: Dogs claws will grow more and more like a human nail, so they need to cut the claws regularly. Dogs who walk well and not otherwise can change the frequency of cutting nails because nails can be shaved during walking. But not all nails shed evenly, so please check your nails regularly if you think "our dog is going to go on a walk. In addition, the fifth claw "wolf" not touching the ground will not be chipped in daily life, so you need to cut it. For cats: Cats living outside have a claw, making it easy to climb and hunt, so if you have a claw, it is not a problem. But when it comes to cats living indoors, it is better to cut a nail clip.Stretching nails can cause them to fold over curtains or rugs or get caught in your family and injury.
