A pet nail grinder is a device that uses a rotary tool to file down a pet's nails instead of cutting them. Pet nail grinders come in various shapes and sizes and can be either battery-operated or corded. They often have different speed settings and sanding attachments to accommodate different sizes of pets and nail thickness. https://letsgadgit.com/products/auto-nail-grinders-usb-charging-nail-clippers-285054642
