No dog likes his nails cut, but cutting-a-boxer's-nailsit is necessary for his well-being. Long nails will cause his feet to splay and make it hard to stand on slippery surfaces. His nails should not make clicking sounds on the floor. They should not be pointy and sharp. They should not scratch and gouge your skin when he touches you. For his health and safety, his nails need to be kept short.
