This pet nail grinder by WOWGO is perfect for your smaller pets. I own two dogs who both hate to have their nails cut. One dog is 10 pounds and the other is 105 pounds, and I can use this grinder on both of them. The grinder has three openings to fit to the size of your pet. You can also take off the case with the openings to reveal the full grinding tip for rapid grinding. I love that it is rechargeable by USB. It takes about 2.5 hours to charge and then will work for 4.5 hours after charging. It has a high and low speed which is a very nice feature. This grinder is quiet during operation, which helps decrease some of the fear with animals. My dogs still do not like their feet being messed with, but this is much quicker and safer. My dogs both have dark colored nails, so I have always worried that I would cut their nails too close causing pain or even bleeding. I don't have to worry about that anymore with this charger.
