My aunt got one and I saw her use it on the chihuahua. That dog is uber active and staying still for something like that is not gonna happen. Plus, she hates getting her nails done. I saw the first use and my aunt had to do Bella’s feet one at a time. Like one now, one a bit later when the dog was chill again, one after that… you get the idea. But it did work very well, didn’t hurt the dog, and once she gets used to it will probably be awesome. She’s just very small and apparently her nails have been mishandled more than properly handled so she doesn’t like people messing with them.
